This is an implementation of ROCCA-S: an efficient AES-based encryption scheme for beyond 5G, a very fast authenticated encryption scheme optimized for platforms with AES-NI or ARM crypto extensions.
ROCCA-S has a 256 bit key size, a 128 bit nonce, processes 256 bit message blocks and outputs a 256 bit authentication tag.
Warning: this implementation is for benchmarking and testing purposes only.
