(15) This disclosure, its aspects and implementations, are not limited to the specific processing techniques, components, modulation formats, frequency examples, or methods disclosed herein. Many additional components and assembly procedures known in the art consistent with the creation and manipulation of a waveform by a modulator and demodulator (modem) are in use with particular implementations from this disclosure. Accordingly, for example, although particular implementations are disclosed, such implementations and implementing components may comprise any components, models, versions, quantities, and/or the like as is known in the art for such systems and implementing components, consistent with the intended operation.

(16) Particular implementations of an all multi-rotational waveform are described. However, as will be clear to those of ordinary skill in the art from this disclosure, the principles and aspects disclosed herein may readily be applied to any modulation, demodulation, and modulation/demodulation device known hereafter as a modem for the creation of a waveform to be carried over a transmission medium for Intermediate Frequency (IF), Radio Frequency (RF), and optical communications systems, such satellite, tactical radio, terrestrial transmission, free-space optical, etc. without undue experimentation.

(17) FIG. 1 illustrates the prior art of a particular implementation of a communications transmission system wherein the forward path (transmitting station to a receiving station) where transmit station contains a transmit modulator and the receiver contains a receiving demodulator using a single waveform. The modem in the prior art utilizes either purpose-built device, typically a dedicated box or a virtualized modem that transmits and is called a modulator. A virtualized modem is an embedded computing environment consisting of one or more CPUs along with hardware acceleration co-processors, with adequate API and software stack to abstract the underlying hardware, and capable of hosting a library of communication waveforms implemented as an all software application.

(18) The modulator outputs either an intermediate frequency (IF) that may be unconverted to a radio frequency (RF) or optical, or directly output from the modulator as a radio frequency or optical, possibly power amplified, and transmitted through free-space, to an airborne, or satellite repeating relay. At the receiving station, the receive modem in the prior art is a purpose-built device, typically a dedicated box or a virtualized modem that receives and is called a demodulator. The demodulator receives (inputs) either an intermediate frequency (IF) that may be down converted from a radio frequency (RF), optical, or directly input from the receive antenna as a radio frequency signal. This embodiment shows a single transmit to a single receive configuration using a single waveform.

(19) FIG. 2 is an alternate embodiment, of the prior art where the modulator and demodulator are combined in a single device known as a modulator/demodulator also known as a modem. As a modem, each station may contain a modem that provides both transmit and receive capability, modulation and demodulation, respectively. The modem at each station may provide a full-duplex communications path. In this embodiment, each station may transmit a single waveform and receive a single waveform. For each path, the waveforms may be the same or dissimilar, but showing the prior art, nevertheless.

(20) FIG. 3 shows an embodiment of the prior art where each component of a purpose-built modem or a virtualized modem supporting an all software application comprises both the transmit or modulation and the receive or demodulation components or functions to create a waveform. The individual processing modules comprise a modem that transmits (modulates) and receives (demodulates) a given (single) waveform is shown.

(21) FIG. 3 shows the top row of boxes (functions) show the various stages that are required to accept user data which is in many cases, but not limited to, serial bit stream, Ethernet (frames), and IP (packets) and received in the Input Conditioning function. The user data may be generated by an application operating as a high-level coding language on a high-performance computing (HPC) system, which includes at least one central processing unit and at least one hardware accelerator. The central processing unit may be a general purpose processing unit or a single purpose processing unit. The hardware accelerator may be a floating point coprocessor, a general purpose graphics processing unit, or a FPGA. The user data is then accepted as bits, bytes, frames, or packets of data into the Input Conditioning function, where it is framed into a suitable transport frame with header information (control bytes, sequence number, type information, etc.) and error checking is added. In the next stage, the data is encoded with Forward Error Correction (FEC) information for data recover at the distant end. In the next stage, if the data is not already in a serial format, the data may be taken from a parallel format to a serial format by a firmware function, transforming into a serial data stream. The next section accepts the serial data stream and then performs the mapping of the bits into symbols to create a waveform constellation as modulated data. The modulated data is then filtered (pulse shaped) with a digital filter implemented. All of the functions described to create the resulting filtered (pulse shaped) waveform may be done in a hardware device or as a virtualized (all software) function. In the specialized modulator or modulator section of a modem, the output then flows to a Digital to Analog Converter (DAC) or to a digital output stream to another stage of processing via Ethernet (frames) and IP (packets). Continuing with FIG. 3, the receive (demodulation) chain, performs the reverse functionality as the transmit (modulation) chain. First it is assumed an Analog to Digital Converter (ADC) has accepted an incoming analog waveform and digitized the signal or the signal was received over an analog or digital Intermediate Frequency (IF) digitized stream such as Ethernet (frames) and IP (packets). The input on the bottom row, right side show the first step is to perform gain control to add amplification or attenuation. The next step is to apply baseband filtering to the digitized stream. The next step is to perform the demodulation of the incoming stream into de-mapped data bits. The next step is to pass the stream to a FEC decoder. FEC decoding is a hardware intensive function. The next step is to verify the integrity of the data via error checking. The next step is to de-frame the frames and remove any control and error checking overhead bits and pass to the user the recovered digital stream as a serial bit stream, framed, or packetized data. All of the functions described to receive and provide the resulting user data may be done in a hardware device or as a virtualized (all software) function.

(22) As shown in FIG. 3, the entire configuration of the modem is controlled by a system controller device or application. The system processor may be a dedicated hardware device or software application as part of a virtualized modem that controls the entire modem. The system controller (control processor) manages the entire unit's health, status, configuration, setup, error checking and in many cases performs the user interface. The virtualized modem may be implemented with a commercial off the shelf high-performance computer server and an open computing framework. The open computing framework may be an open source application programming interface.

(23) FIG. 4 shows the preferred embodiment of the transmit modem utilizing the described invention. All of the components described in the transmit section of FIG. 3 are present, but there are multiple instantiations of the transmitter utilized to perform the method. In the prior art, only one modulator would be present, but in the preferred embodiment, using highly integrated technology or virtualized modem technology, more than one transmit modem must be present. There is no limit for the number of transmit modulators that are implied using the described method. Each transmit chain (modulator) may be present and ready to accept data from the input parser and the input parser is programmed to carry out the rules as to how an incoming user data stream's data is parsed and each portion of the incoming stream is then passed to a given modulator to perform a particular type of modulation or resulting waveform. Modulated data streams as outputs from each modulator are then combined to modulated waveform streams by a combiner. While discrete logic parts would be highly inefficient, these functions may easily be realized using a virtualized modem approach, where all modulation is carried out by a software application. The rules for carrying out the parsing of the serial data stream, incoming frames or packets, define the level of security placed on the transmitted data stream. The resulting transmitted waveform may be spectrally bound to the same power, frequency, bandwidth, modulation, spectral efficiency, spectral containment, waveform family (type), etc., but this is not an absolute requirement. In fact, each modulator, in turn, may change the characteristics of the transmitted waveform each time it is selected to transmit a portion of the data or it may remain the same each time it is chosen to transmit.

(24) FIG. 5 shows the preferred embodiment of the receive modem utilizing the described invention. All components described in the receive section of FIG. 3 are present, but there are multiple instantiations of the receiver utilized to perform the method. In the prior art, only one demodulator would be present, but in the preferred embodiment, using highly integrated technology or virtualized modem technology, more than one receive modem must be present. There is no limit for the number of receive demodulators that are implied using the described method. Each receive chain (demodulator) may be present and ready to accept a modulated waveform from the input splitter and the rules of the input parser (from the transmit) may be programmed to carry out the rules as to how an incoming modulated stream's data was parsed and each portion of the incoming modulated stream is then passed to a given demodulator to perform a particular type of demodulation or resulting waveform. In an alternate embodiment, where a priori knowledge is not required, a bank of demodulators may blindly demodulate the incoming waveform streams, this would not be the most optimal approach and would be considered a brute force way to implement the described approach. While discrete logic parts would be highly inefficient, these functions may easily be realized using a virtualized modem approach, where all demodulation is carried out by a software application. The software application (the modem application) may be operating as a high-level coding language on a high performance computer (HPC) system, which includes at least one central processing unit and at least one hardware accelerator. The central processing unit may be a general purpose processing unit or a single purpose processing unit. The hardware accelerator may be a floating point coprocessor, a general purpose graphics processing unit, or a FPGA. The modem application may be computer software, or a program or series of programs, such as one that may be used for mobile devices or for desktop applications, and may be downloaded and installed all at once. The modem application may run inside an operating system until the modem application is closed. The rules for carrying out the original parsing of the serial data stream, incoming frames or packets, at the modulator, resulting in the modulated waveforms, this results in the level of security placed on the transmitted data stream. The resulting transmitted waveform may be spectrally bound to the same power, frequency, bandwidth, modulation, spectral efficiency, spectral containment, waveform family (type), etc., but this is not an absolute requirement. Unless an unwanted listener had the exact knowledge, configuration, requisite number of demodulators, etc. there would be minimal probability of interception of an incoming data stream. In fact, if a priori knowledge of a given waveform is known, each demodulator, in turn, may change the characteristics of the receive waveform each time it is selected to receive a portion of the data or it may remain the same each time it is chosen to receive.

(25) FIG. 6 shows a preferred embodiment where the transmit and receive functions are combined into a single platform to provide a modem containing virtualized waveforms, where a single hardware platform known as a High Performance Computing (HPC) device is supporting the plurality of waveforms as software applications.

(26) FIG. 7 shows a preferred embodiment where the transmit and receive functions are combined into a single platform to provide a modem using a single transmit medium implementing the described method. The input parser follows preprogrammed rules for accepting user data and passing the data to a given waveform to be modulated. In FIG. 7, Data 1 would be passed to Waveform 1, and then the data is modulated by modulator for Waveform 1 and then transmitted as Waveform Data 1. Data 2 would be passed to Waveform 2, and then the data is modulated by modulator for Waveform 2 and then transmitted as Waveform Data 2. Data 3 would be passed to Waveform 3, and then the data is modulated by modulator for Waveform 3 and then transmitted as Waveform Data 3. Data N would be passed to Waveform N, and then the data is modulated by modulator for Waveform N and then transmitted as Waveform Data N. Finally, Data N+1 would be passed to Waveform 1, and then the data is modulated by modulator for Waveform 1 and then transmitted as Waveform Data N+1. At the receiving side, for a preferred embodiment, all demodulators would be instantiated and ready to receive data. However, knowing the rules for creating the waveforms, a priori, would allow each demodulator to be standing by or ready to receive the data in turn as each packet is received. As show in FIG. 7, Waveform Data 1 would be passed to Waveform 1, and then the data is demodulated by demodulator for Waveform 1 and then output as Data 1. Waveform Data 2 would be passed to Waveform 2, and then the waveform data is demodulated by demodulator for Waveform 2 and then output as Data 2. Waveform Data 3 would be passed to Waveform 3, and then the waveform data is demodulated by demodulator for Waveform 3 and then output as Data 3. Waveform Data N would be passed to Waveform N, and then the waveform data is demodulated by demodulator for Waveform N and then output as Waveform Data N. Finally, Waveform Data N+1 would be passed to Waveform 1, and then the waveform data is demodulated by demodulator for Waveform 1 and then output as Data N+1. The preferred embodiment is supported and contains virtualized waveforms, where a single hardware platform known as an HPC device is supporting the plurality of waveforms as software applications.

(27) FIG. 8 shows an alternate embodiment where dummy data is inserted into the user data stream to provide additional obfuscation of a resulting waveform based on additional exercising of the method to provide dummy or false data into the data stream. Unless an unwanted listener knows the precise configuration, a priori, of the sequence information, the dummy data would confuse the unwanted user, since data would be out of place or result in a misalignment of an incoming data stream or flow. The transmit and receive functions are combined into a single platform to provide a modem using a single transmit medium implementing the described method. The input parser follows preprogrammed rules for accepting user data and passing the data to a given waveform to be modulated along with the dummy data. In FIG. 8, Data 1 would be passed to Waveform 1, and then the data is modulated by modulator for Waveform 1 and then transmitted as Waveform Data 1. Dummy Data would be passed to Waveform 2, and then the data is modulated by modulator for Waveform Dummy 2 and then transmitted as Waveform Dummy 2. Data 3 would be passed to Waveform 3, and then the data is modulated by modulator for Waveform 3 and then transmitted as Waveform Data 3. Data N would be passed to Waveform N, and then the data is modulated by modulator for Waveform N and then transmitted as Waveform Data N. Finally, Data N+1 would be passed to Waveform 1, and then the data is modulated by modulator for Waveform 1 and then transmitted as Waveform Data N+1. Dummy data may be inserted at any desired cycle based on the rules of the configuration. At the receiving side, for an alternate embodiment, all demodulators would be instantiated and ready to receive data. However, knowing the rules for creating the waveforms, a priori, would allow each demodulator to be standing by or ready to receive the data in turn as each packet is received. As show in FIG. 8, Waveform Data 1 would be passed to Waveform 1, and then the data is demodulated by demodulator for Waveform 1 and then output as Data 1. Waveform Dummy 2 would be passed to Waveform 2, and then the waveform data is demodulated by demodulator for Waveform 2 and then discarded. Waveform Data 3 would be passed to Waveform 3, and then the waveform data is demodulated by demodulator for Waveform 3 and then output as Data 3. Waveform Data N would be passed to Waveform N, and then the waveform data is demodulated by demodulator for Waveform N and then output as Waveform Data N. Finally, Waveform Data N+1 would be passed to Waveform 1, and then the waveform data is demodulated by demodulator for Waveform 1 and then output as Data N+1. In the described method, only actual real data would be output to the user and all dummy data used to obfuscate the channel would be passed to the user. The alternate embodiment is supported and contains virtualized waveforms, where a single hardware platform known as an HPC device is supporting the plurality of waveforms as software applications.

(28) FIG. 9 shows an alternate embodiment where each modulators output may be passed over a different transmission path. Each modulator may be assigned to a transmission path such as, but not limited, to satellite, airborne, optical, tactical radio, terrestrial radio, etc. Each modulation scheme chosen may be assigned a dedicated modulation type or the modulation type may be altered based on the rules assigned by the input parser. FIG. 9 demonstrates the transmit modulator using a plurality of transmit mediums implementing the described method. The input parser follows preprogrammed rules for accepting user data and passing the data to a given waveform to be modulated. In FIG. 9, Data 1 would be passed to Waveform 1, and then the data is modulated by modulator for Waveform 1 and then transmitted as Waveform Data 1 over a satellite transmission path. Data 2 would be passed to Waveform 2, and then the data is modulated by modulator for Waveform 2 and then transmitted as Waveform Data 2 over a tactical radio transmission path. Data 3 would be passed to Waveform 3, and then the data is modulated by modulator for Waveform 3 and then transmitted as Waveform Data 3 over a third transmission path. Data N would be passed to Waveform N, and then the data is modulated by modulator for Waveform N and then transmitted as Waveform Data N over an optical transmission path. Finally, Data N+1 would be passed to Waveform 1, and then the data is modulated by modulator for Waveform 1 and then transmitted as Waveform Data N+1 over any one of the transmission paths. At the receiving side, for an alternate embodiment, all demodulators would be instantiated and ready to receive data. However, knowing the rules for creating the waveforms, a priori, would allow each demodulator to be standing by or ready to receive the data in turn as each packet is received. As show in FIG. 9, Waveform Data 1 would be passed to Waveform 1, and then the data is demodulated by demodulator for Waveform 1 and then output as Data 1. Waveform Data 2 would be passed to Waveform 2, and then the waveform data is demodulated by demodulator for Waveform 2 and then output as Data 2. Waveform Data 3 would be passed to Waveform 3, and then the waveform data is demodulated by demodulator for Waveform 3 and then output as Data 3. Waveform Data N would be passed to Waveform N, and then the waveform data is demodulated by demodulator for Waveform N and then output as Waveform Data N. Finally, Waveform Data N+1 would be passed to Waveform 1, and then the waveform data is demodulated by demodulator for Waveform 1 and then output as Data N+1. The use of dummy packets may also be brought to bear using multiple transmission paths. The alternate embodiment is supported and contains virtualized waveforms, where a single hardware platform known as an HPC device is supporting the plurality of waveforms as software applications.

(29) FIG. 10 shows an alternate embodiment where COMSEC algorithm unique for each waveform type is applied to the respective User Data. Unless an unwanted listener knows the precise COMSEC algorithm and shared secret required for detection and decryption of a given waveform, the user data is encrypted and obfuscated. The transmit and receive functions are combined into a single platform to provide a modem using a single transmit medium implementing the described method. The input parser follows preprogrammed rules for accepting user data, applying the appropriate COMSEC for a given waveform, and passing the ciphertext to a given waveform to be modulated. In FIG. 10, Data 1 would be encrypted using a cryptographic algorithm and passed to Waveform 1, and then the ciphertext is modulated by modulator for Waveform 1 and then transmitted as Waveform Data 1. Data 2 would be encrypted using another cryptographic algorithm and passed to Waveform 2, and then the ciphertext is modulated by modulator for Waveform 2 and then transmitted as Waveform Data 2. Data N would be encrypted using another cryptographic algorithm and passed to Waveform N, and then the ciphertext is modulated by modulator for Waveform N and then transmitted as Waveform Data N. At the receiving side, for an alternate embodiment, all demodulators would be instantiated and ready to receive data. However, knowing the rules for creating the waveforms, a priori, would allow each demodulator to be standing by or ready to receive the data in turn as each packet is received. As shown in FIG. 10, Waveform Data 1 would be passed to Waveform 1, and then the data is demodulated by the demodulator for Waveform 1, and then the appropriate cryptographic algorithm and shared secret is applied to decrypt the ciphertext, and then output as Data 1. Waveform Data 2 would be passed to Waveform 2, and then the waveform data is demodulated by the demodulator for Waveform 2, and then the appropriate cryptographic algorithm and shared secret is applied to decrypt the ciphertext, and then output as Data 2. Waveform Data N would be passed to Waveform N, and then the waveform data is demodulated by the demodulator for Waveform N, and then the appropriate cryptographic algorithm and shared secret is applied to decrypt the ciphertext, and then output as Waveform Data N.

(30) Using the described method, the parsing of the data may be done in any manner of ways: Bit-by-bit Byte-by-byte Frame-by-frame Packet-by-packet FEC block-by-FEC block Crypto logical boundary by Crypto logical boundary

(31) In no way is the parsing of the data and the delivery to a given waveform mandated by a fixed boundary but may be defined to suite a user's needs. Additionally, the data passed into the waveform modulators may be scrambled, encrypted, re-ordered, and dummy data (bits, bytes, frames, and packets) added to further obfuscate the data stream.

(32) In an alternate embodiment, a Transmission Security (TRANSEC) may be applied to the user data stream with or without applying COMSEC algorithm.

(33) Furthermore, the assignment of waveform modulator or transmission path utilized by said modulator may be assigned sequentially, mathematically, pseudo randomly, linearly, non-linearly, etc. and the receive may be instructed a priori as to the given incoming sequence or the method may be run blindly, so the receiving end must have the correct demodulators present to attempt to lock on or decode any and all streams.

(34) The operation of assignment of the waveform selection for the transmission and resulting reception requires one that is unified between transmit and receive based on the selection of a particular modulator and resulting demodulator at the transmit and receiving end, respectively. Additionally, the algorithm selected for performing the parsing of the incoming data follows a unified set of rules between the respective ends (transmit and receive) that allows the choice of a given path to be the novelty of the invention thus providing the protection of the data as a result of the diverse waveforms and/or transmission paths. The assignment of the waveform for transmission may also be relayed to the receiving demodulator via a signaling channel, in a manner to provide a dynamic assignment of the sequence of waveforms. The assignment of the transmission sequence (assignment of transmission waveform or channel) may be sent via a secondary channel (wireless, wired, a priori instruction, etc.) through the use of a dedicated low-probability of interference (LPI) and low-probability of detection (LPI/LPD) signal as a way to notify the end receiving demodulator.

(35) The same method for rotational waveforms as described in the patent disclosure can be applied to a whole different application; specifically, for the purposes of Network Optimization to deliver quality of service to the end user. In cases where there is network congestion or complete loss of a particular communication path, the same method of rotational waveforms can be used redistribute transmission of user data across one or more communication paths, each requiring its own specific communication waveform. The one and only difference between the method as described for the data security use case from the Network Optimization use case are the rules for waveform rotation. In the data security use case, the rules for waveform rotation are governed by mathematical equations and random numbers with the intent of creating obfuscation for a potential network intruder. On the other hand, the rules of waveform rotation for the Network Optimization use case is governed by algorithms that aim to optimize a network performance parameter, such Continuous Information Rate (CIR), minimum latency, throughput, reliability, data priority, or any other user quality of service parameter.

(36) Switching from one transmission path may involve the synchronization between a multitude of repeating relays such as a simply repeating relay for balloon, airborne, or satellite, as well as a sophisticated relay such as a high-throughput satellite (HTS), cellular network, etc., where the waveforms are completely synchronized between the end points as well as interfacing to the processed and non-processed relays and repeating stations. This may be viewed as make-before-break connection as well as a break-before-make operation when switching the waveforms.

(37) The described system supports any modulation method including the use of both frequency hopping spread spectrum (FHSS) and direct sequence spread spectrum (DSSS) and hybrid spread spectrum which is the combined FHSS and DSSS, as well as fixed/continuous carrier and burst (periodic) transmission carriers.

(38) The following are particular implementations with the multi-rotational waveform scheme and the use of these methods are provided as non-limiting examples. 1. A user requires data to be passed to an end satellite station. Using the described invention, a flow is created to encapsulate the user data for transport over the network as Ethernet frames and/or IP packets to the data center. The modulator uses three waveforms to accomplish the desired method. The first modulation scheme is Digital Video Broadcast-Satellite Version 2 (DVB-S2) using QPSK rate 1/2 FEC, the second modulation scheme is the NATO Standard Agreement (STANG) 4486 using QPSK rate 1/2 FEC, and the third is proprietary Multi Access Waveform (MAW) based on Time Division Multiple Access (TDMA) utilizing Viterbi and Reed-Solomon (RS) rate 1/2 encoding and QPSK modulation. The configuration transmits each packet in a manner where every packet sequentially rotates (advances) to the next waveform in a round-robin fashion. The parsing and recombining of the user data is handled on a frame-by-frame boundary. A repeating relay satellite enables communications over a single transmission carrier between the satellite teleport and end satellite receiving station. The end user must have all three waveforms available to fully decode each of the transmitted frames being passed over the satellite link. The described method provides a secure method to pass the packets to the end user and the data is transferred. Should any one of the waveforms not be available nor supported, a portion of the data will be missing in the data stream. 2. A user requires data to be passed to an end satellite station. Using the described invention, a flow is created to encapsulate the user data for transport over the network as Ethernet frames and/or IP packets to the data center. The modulator uses four waveforms to accomplish the desired method. The first modulation scheme is Digital Video Broadcast-Satellite Version 2 (DVB-S2x) using 16-APSK rate 3/4 FEC, the second modulation scheme is the NATO Standard Agreement (STANG) 4486 using QPSK rate 1/2 FEC, the third is proprietary Viterbi, and Reed-Solomon (RS) waveform using 8PSK rate 9/10 FEC, and the fourth is a proprietary MAW based Frequency Division Multiple Access (FDMA) utilizing 8PSK rate 2/3 FEC with a unique Gold Code. The configuration transmits each packet in a manner where every packet randomly rotates (advances) to the next waveform according to a Pseudo Random Number Generator (PRBS) or a True Random Number Generator (TRNG) that is seeded with a common initialization vector (IV). The parsing and recombining of the user data is handled on a byte boundary. However, after the end of every fourth packet a dummy packet is inserted to obfuscate the user data. A repeating relay satellite enables communications over a single transmission carrier between the satellite teleport and end satellite receiving station. The end user must have all four waveforms available to fully decode each of the transmitted frames but must be aware of the use of dummy packets and discard the dummy packet after being passed over the satellite link. The described method provides a secure method to pass the packets is established to the end user and the data is transferred but discard unwanted dummy packets. Should any one of the waveforms not be available nor supported, a portion of the data will be missing in the data stream. 3. In particular implementations of the system described in example 2, dummy data may be inserted into the user data to obfuscate the actual user data. Should the receiving end not remove the data, then data corruption would result. 4. A user requires data to be passed to an end station. Using the described invention, three communication paths are established: Satellite, line-of-sight terrestrial radio link, and an airborne relay. Three flows are created to encapsulate the user data for transport over all three paths may be used. The modulator uses three waveforms with three different paths to accomplish the desired method. The first modulation scheme is Digital Video Broadcast-Satellite Version 2 (DVB-S2) over the satellite link, the second modulation scheme is uses a DVB-T2 terrestrial radio link, and the third is proprietary Viterbi, and Reed-Solomon (RS) waveform over the airborne relay. Furthermore, each transmission path implements its own unique COMSEC method. The configuration transmits each packet in a manner where every packet sequentially rotates (advances) through all even indices in the list of waveforms. The parsing and recombining of the user data is handled on a COMSEC Crypto boundary. The end user must have all three transmission paths, all waveforms, and knowledge of each COMSEC algorithm and shared secret available to fully decode and decrypt each of the transmitted frames being passed over the links. The described method provides a secure method to pass the packets is established to the end user and the data is transferred. Should any one of the transmission paths, waveforms, or cryptographic method and shared secret not be available nor supported, a portion of the data will be missing in the data stream. 5. In particular implementations of the system described in example 4, dummy data may be inserted on any one of the links to obfuscate the actual user data.
