  • Method and system for constant time cryptography using a co-processor
    Patent number: 10243727
    Abstract: The present disclosure presents methods, apparatuses, and systems to bolster communication security, and more particularly to utilize a constant time cryptographic co-processor engine for such communication security. For example, the disclosure includes a method for secure communication, comprising receiving encrypted data at a receiving device; obtaining a randomization for at least one bit of the encrypted data; modifying an execution of a cryptographic algorithm on the at least one bit to obtain a randomized cryptographic algorithm based on the randomization; and executing the randomized cryptographic algorithm on the at least one bit of encrypted data to recover original data associated with the encrypted data.
    Type: Grant
