Provided is a method of an electronic device for performing ultra wide band (UWB) communication. The method includes receiving upper bit information including pre-set at least one parameter via a UWB command interface (UCI), obtaining slot count information and key information including a constant key value, and performing static scrambled timestamp sequence (STS) generation, based on the upper bit information, the slot count information, and the key information.

Methods and systems for securing data using random bits and encoded key data. A plurality of true random number generator (TRNG) disks and a plurality of key data sets are provided. A key data set from the plurality of key data sets is associated with each of the plurality of TRNG disks, respectively. The key data set comprises at least a block of random bits of an associated TRNG disk. An encoded key data set is formed by encoding at least two of the key data sets together. The source data can be encrypted with the encoded key data set to produce a quantity of encrypted data. The encrypted data can be decrypted with the encoded key data set or the at least two of the key data sets retrieved from the associated TRNG disks.

A computer-implemented method of generating a one-time pad for use in encryption, the method comprising: determining a seed sequence and an ordered set of initial values; and for each initial value, computing a sequence of terms, wherein each term of the sequence is computed by combining at least one other term of that sequence with at least one term of a previous one of the sequences using modular arithmetic, the previous sequence being the sequence generated for the previous initial value or, in the case of the first initial value, the seed sequence. Rather than using the final sequence as a direct basis for the one-time pad, one or more additional steps are taken to disrupt the final sequence, in order to improve the security of the method and the resulting one-time pad.

An AI-based approach to Garbled speech (GS) detection. Machine learning (ML) models are created that can distinguish between GS speech and non-GS speech with high accuracy. The machine learning models take as input an encoded speech frame that has passed a CRC check. The input data/predictors to the models are a selected set of information elements (IEs) (i.e., a set of one or more bits) of the encoded speech frame. The selected IEs are a part of the input parameters to the speech decoder. It is possible to operate on single encoded speech frames, in contrast to using decoded frames, which requires taking a previous encoded frame into account for being able to perform the decoding.

Systems, apparatuses, and methods are disclosed for quantum entanglement authentication (QEA). An example method includes transmitting, a first electronic identification of a first subset of a first set of entangled quantum particles to a first computing device, transmitting, by the classical communications circuitry, a second number to a second computing device, wherein each entangled quantum particle in the first set of entangled quantum particles is entangled with a respective entangled quantum particle in a second set of entangled quantum particles, receiving, from the first computing device, a first number, the first number representative a measurement of the first subset of the first set of the entangled quantum particles, and in an instance in which the second number corresponds to the first number, authenticating a session between the first computing device and the second computing device.

A technique for generating a keystream (128) for ciphering or deciphering a data stream (122) is provided. As to a method aspect of the technique, a nonlinear feedback shift register, NLFSR (112), including n register stages implemented in a Galois configuration is operated. At least one register stage of the implemented n register stages is representable by at least one register stage of a linear feedback shift register, LFSR. A first subset of the implemented n register stages is representable by a second subset of a second NLFSR. A number of register stages receiving a nonlinear feedback in the second NLFSR is greater than one and less than a number of register stages receiving a nonlinear feedback in the implemented NLFSR. The keystream (128) is outputted from a nonlinear output function (118). An input of the nonlinear output function (118) is coupled to at least two of the implemented n register stages of the NLFSR (112).

An encryption specification named “MetaEncrypt” implemented as a method and associated apparatus is disclosed for unbreakable encryption of data, code, applications, and other information that uses a symmetric key for encryption/decryption and to configure the underlying encryption algorithms being utilized to increase the difficulty of mathematically modeling the algorithms without possession of the key. Data from the key is utilized to select several encryption algorithms utilized by MetaEncrypt and configure the algorithms during the encryption process in which block sizes are varied and the encryption technique that is applied is varied for each block. Rather than utilizing a fixed key of predetermined length, the key in MetaEncrypt can be any length so both the key length and key content are unknown. MetaEncrypt's utilization of key data makes it impossible to model its encryption methodology to thereby frustrate cryptographic cracking and force would be hackers to utilize brute force methods to try to guess or otherwise determine the key.

The present disclosure is directed to secure computations and transmission of encrypted data over a network. Two unequal unsigned integer numbers are used as keys, which are kept secret by users. Each key is supplied as the seed to a uniform pseudorandom number generator, and follows an algorithm to encrypt and decrypt a communications channel between two endpoints on the network. The communications channel is a stream of bits representing any data that may be represented or stored by a computer capable of processing binary data. In one illustrative embodiment, a network has multiple endpoints, such as different terminals disposed at different locations (for example, terminals at various branches of a financial institution that are connected to a common network). Using keys that are specific to transactions between specified terminals allows for greater security of the encrypted transmissions.

A streaming one time Pad cipher using a One Time Pad (OTP) provides secure data storage and retrieval. The data that is encrypted using the one time pad is stored in a repository that is separate from the generation and/or storage for the one time pad.
