STRIBOB: Authenticated Encryption from GOST R 34.11-2012 LPS Permutation
Abstract
Authenticated encryption algorithms protect both the confidentiality and integrity of messages in a single processing pass. In this note we show how to utilize the $L \circ P \circ S$ transform of the Russian GOST R 34.11-2012 standard hash ``Streebog'' to build an efficient, lightweight algorithm for Authenticated Encryption with Associated Data (AEAD) via the Sponge construction and BLNK padding. The proposed algorithm ``StriBob'' has attractive security properties, is faster than the Streebog hash alone, twice as fast as the GOST 28147-89 encryption algorithm, and requires only a modest amount of running-time memory. StriBob is a Round 1 candidate in the CAESAR competition.
