I am making this work from August 1998 available for historical reasons. It has been cited as an ``unpublished manuscript'' more than two dozen times over the years -- even though it has not been publ...
Defined in the standard GOST 28147-89, GOST is a Soviet and Russian government standard symmetric-key block cipher. GOST has the 64-bit block size and a key length of 256 bits. It is a Feistel network...
STRIBOB: Authenticated Encryption from GOST R 34.11-2012 LPS Permutation
StriBob Authenticated Encryption GOST R 34.11-2012
2016/1/23
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 th...
Improved Cryptanalysis on Reduced-Round GOST and Whirlpool Hash Function (Full Version)
hash function GOST Whirlpool
2016/1/9
The GOST hash function family has served as the new Russian national hash
standard (GOST R 34.11-2012) since January 1, 2013, and it has two members, i.e., GOST-
256 and GOST-512 which correspond to...
A lightweight-friendly modifcation of GOST block cipher
GOST 28147-89 lightweight cryptography FPGA
2016/1/4
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.
Improved (Pseudo) Preimage Attacks on Reduced-Round GOST and Gr鴖tl-256 and Studies on Several Truncation Patterns for AES-like Compression Functions (Full Version)
hash function cryptanalysis preimage
2015/12/29
In this paper, we present improved preimage attacks on the reduced-round GOST hash
function family, which serves as the new Russian hash standard, with the aid of techniques such as the
rebound atta...
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 compress...
Algebraic Aspects of the Russian Hash Standard GOST R 34.11-2012
hash functions one-way functions
2014/3/10
New GOST R 34.11-2012 standard has been recently selected by the Russian government to replace the old one. The algorithm is based on the hash function Stribog introduced in 2010. The high-level struc...
