STRIBOB: Authenticated Encryption from GOST R 34.11-2012 LPS Permutation
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◦P ◦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 propos...
متن کاملCryptanalysis of GOST R Hash Function
GOST R is the hash function standard of Russia. This paper presents some cryptanalytic results on GOST R. Using the rebound attack technique, we achieve collision attacks on the reduced round compression function. Result on up to 9.5 rounds is proposed, the time complexity is 2 and the memory requirement is 2 bytes. Based on the 9.5-round collision result, a limited birthday distinguisher is pr...
متن کاملA lightweight-friendly modifcation of GOST block cipher
We study the possibility of GOST block cipher modification in such way, that it would resist Isobe and Dinur-Dunkelman-Shamir attacks, and, at the same time, would be still lightweight-friendly.
متن کاملDifferential Cryptanalysis of GOST
GOST 28147-89 is a well-known block cipher and the official encryption standard of the Russian Federation. A 256-bit block cipher considered as an alternative for AES-256 and triple DES, having an amazingly low implementation cost and thus increasingly popular and used [22, 23, 30, 24, 41]. Until 2010 researchers unanimously agreed that: “despite considerable cryptanalytic efforts spent in the ...
متن کاملAlgebraic Complexity Reduction and Cryptanalysis of GOST
GOST 28147-89 is a well-known Russian government encryption standard. Its large key size of 256 bits at a particularly low implementation cost [77] make that it is widely implemented and used [66, 96, 62, 77, 82]. In 2010 GOST was submitted to ISO to become an international standard. GOST was analysed by Schneier, Biham, Biryukov, Dunkelman, Wagner, various Australian, Japanese, and Russian sci...
