ePrint Report: Multiplex: TBC-based Authenticated Encryption with Sponge-Like Rate

Thomas Peters, Yaobin Shen, François-Xavier Standaert

Authenticated Encryption (AE) modes of operation based on Tweakable Block Ciphers (TBC) usually measure efficiency in the number of calls to the underlying primitive per message block. On the one hand, many existing solutions reach a primitive-rate of 1, meaning that each n-bit block of message asymptotically needs a single call to the TBC with output length n. On the other hand, while these modes …
