In this paper, we propose Rocca-S, an authenticated encryption scheme with a 256-bit key and a 256-bit tag targeting 6G applications bootstrapped from AES. Rocca-S achieves an encryption/decryption speed of more than 200 Gbps in the latest software environments. In hardware implementation, Rocca-S is the first cryptographic algorithm to achieve speeds more than 2 Tbps without sacrificing other metrics such as occupied silicon area or power/energy consumption making Rocca-S a competitive choice satisfying the requirements of a wide spectrum of environments for 6G applications.
