ePrint Report: Authenticated Encryption for Very Short Inputs

Alexandre Adomnicai, Kazuhiko Minematsu, Junji Shikata

We study authenticated encryption (AE) modes dedicated to very short messages, which are crucial for Internet-of-things applications. Since the existing general-purpose AE modes need at least three block cipher calls for non-empty messages, we explore the design space for AE modes that use at most two calls. We proposed a family of AE modes, dubbed Manx, that work when the total input length is less than …
