In this paper, we propose two hardware optimized authenticated encryption schemes: TriviA-v2 and uTriviA. Both TriviA-v2, an efficient hardware optimization of TriviA-0-v1, and uTriviA are based on (i) a stream cipher for generating keys for the ciphertext and the tag, and (ii) a pairwise independen...
