Latest Patents

Cooreman's latest patents include an "Apparatus for cryptographic operations on information and associated methods." This apparatus features an encryption circuit that utilizes a block function circuit to generate multiple blocks of output data. Notably, a block of output data with an initial sequence number incorporates more state than that used by a ChaCha20 block function. The keystream is generated in two parts, with the first part derived from the initial sequence number and the second from blocks with different sequence numbers.

Another significant patent is for "Hardware countermeasures against DFA attacks on AES operations." This system and method enhance AES encryption while detecting potential DFA attacks. The method involves introducing faults between specific operations in the encryption process to identify possible attacks. Importantly, the same hardware is utilized for both the original and repeated rounds of encryption, minimizing additional hardware requirements and maintaining execution time impact at 10% or less.
