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.

Abstract: A decompression engine may include an input configured to receive an input code comprises one or more bits from a bitstream of encoded data, a symbol decoder coupled with the input, where the symbol decoder is configured to calculate, based on the input code, a plurality of candidate addresses each corresponding to a code group. The symbol decoder may further include a group identifier module coupled with the symbol decoder, wherein the group identifier module is configured to identify one of the plurality of code groups corresponding to the input code, and a multiplexer coupled with the group identifier module, wherein the multiplexer is configured to select as a final address one of the plurality of candidate addresses corresponding to the identified code group.
