Embodiments of present disclosure relates to and systems to reduce propagation delays in hardware implementation of 3GPP confidentiality or standardized algorithm 128-EEA3 and 3GPP integrity algorithm 128-EIA3 using ZUC module. The reduction of the propagation delays is achieved by improving or optimizing secondary critical paths, which are subsequent to primary critical path, related to the 3GPP confidentiality or standardized algorithm 128-EEA3 and the 3GPP integrity algorithm 128-EIA3. Non-conventional modifications in the hardware implementation are proposed for the improvement or optimization.

A scheme for securely transferring a patient data file to an intended recipient regardless of a transfer mode selected by a sender. Encryption system executing at the sender device is operative to encrypt each plaintext data line of a file, one by one, using a symmetric key and a starting IV that is incremented per each line, resulting in corresponding ciphertext lines added to an encrypted file. A hash is generated based on the encrypted file. An encrypted header containing the symmetric key, starting IV and the hash is generated using a public key of the recipient, which is appended to the encrypted file. The encrypted header and associated encrypted file are transmitted to the recipient in any manner. Upon receipt, the recipient decrypts the encrypted header using a private key to obtain the symmetric key, starting IV and the hash, which are used by the recipient to validate and decrypt the encrypted file on a line-by-line basis.

In one embodiment, a processor includes a memory hierarchy and a core coupled to the memory hierarchy. The memory hierarchy stores encrypted data, and the core includes circuitry to access the encrypted data stored in the memory hierarchy, decrypt the encrypted data to yield decrypted data, perform an entropy test on the decrypted data, and update a processor state based on a result of the entropy test. The entropy test may include determining a number of data entities in the decrypted data whose values are equal to one another, determining a number of adjacent data entities in the decrypted data whose values are equal to one another, determining a number of data entities in the decrypted data whose values are equal to at least one special value from a set of special values, or determining a sum of n highest data entity value frequencies.

Systems and methods are described for providing secure storage of data sets while enabling efficient deduplication of data. Each data set can be divided into fixed-length blocks. The plaintext of each block can be convergently encrypted, such as by using a hash of the plaintext as an encryption key, to result in block-level ciphertext that can be stored. If two data sets share blocks, the resulting block-level ciphertext can be expected to overlap, and thus duplicative block-level ciphertexts need not be stored. A manifest can be created to facilitate re-creation of the data set, which manifest identifies the block-level ciphertexts of the data set and a key by which each block-level ciphertext was encrypted. By use of block-level encryption, nearly identical data sets can be largely deduplicated, even if they are not perfectly identical.

Embodiments described herein provide for system and methods to enable the secure streaming of real-time location data between electronic devices. One embodiment provides for a non-transitory machine-readable medium storing instructions to perform operations comprising creating record to specify a location streaming relationship between a first device registered with a first user account and a second device registered with a second online account, the record including a secret key. The record is stored to an online datastore and shared between the first user account and the second online account. The location data stream can be encrypted using the secret key stored in the record.

A wideband chaotic waveform that is rateless in that it may be modulated at virtually any rate and has a minimum of features introduced into the waveform. Further, the waveform provided may be operated below a signal to noise ratio wall to further enhance the LPD and LPE aspects, thereof. Additionally, the present disclosure may provide a mix of coherent and non-coherent processing techniques applied to signal samples to efficiently achieve coarse synchronization with a waveform that is faster, more efficient and more accurate than using time domain signal correlators alone.

A secure programming system and method for provisioning and programming a target payload into a programmable device mounted in a programmer. The programmable devices are provisioned with a job package created by a user on a host system and deployed on a device programmer. The secure programming system supports a hardware security module on the host system that can be accessed remotely from the device programmer using coordinated sets of template and mechanism dictionaries linked to a security API coupled to the hardware security module.

Systems, apparatuses, methods, and computer program products are disclosed for post-quantum cryptography (PQC). An example method includes transmitting a first portion of an electronic communication to a client device over a non-PQC communications channel. The example method further includes transmitting a second portion of the electronic communication to the client device over a PQC communications channel. In some instances, the first portion of the electronic communication may comprise overhead data, and the second portion of the electronic communication may comprise payload data.

A computing device having a tightly attached or closely attached hardware accelerator directly coupled with one or more processors for efficient uses of the hardware accelerator for executing specific functions are described. According to an embodiment, the hardware accelerator is instantiated inside the main processor unit and interfaces to a load-store unit (LS) using virtual addresses. The hardware accelerator instantiated inside the main processing unit (e.g., core) is referred to as a tightly attached hardware accelerator. In an alternative embodiment, the hardware accelerator is instantiated inside a cluster of processor cores. The hardware accelerator that is instantiated inside the cluster of processor cores but not inside a specific processor core is referred to as a closely attached hardware accelerator.

A method for storing a data file (DF) on a storage entity (SE) includes receiving, by a proxy (PE) and from a computing entity (CE), a plurality of hash values corresponding to a plurality of blocks of the DF. The PE may check whether the plurality of blocks of the DF are stored in the SE based on the plurality of hash values. Based on determining that at least a subset of the plurality of blocks of the DF are not being stored in the SE, the PE may compute a secret associated with an encryption key. The PE may transmit, to the CE, the secret. The PE may receive, from the CE, information including storage locations of the subset of the plurality of blocks within the SE and one or more hash values, of the plurality of hash values, associated with the subset of the plurality of blocks.
