New Linear Attacks on Block Cipher GOST
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 of 32 rounds. In 2010, GOST was submitted to ISO 18033 to become a worldwide industrial encryption standard. GOST 28147-89 has also been published as informational RFC 5830 with IETF. In this pape...
متن کاملImproved Attacks on Full GOST
GOST is a well known block cipher which was developed in the Soviet Union during the 1970’s as an alternative to the US-developed DES. In spite of considerable cryptanalytic effort, until very recently there were no published single key attacks against its full 32-round version which were faster than the 2 time complexity of exhaustive search. In February 2011, Isobe used in a novel way the pre...
متن کاملAn Improved Differential Attack on Full 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 is becoming increasingly popular [?,15]. Until 2010 researchers unanimously agreed that: “despite considerable cryptanalytic efforts spent in the past 20 years, G...
متن کاملOn Multiple Symmetric Fixed Points in GOST
In this article the author revisits the oldest attack on GOST known, the Kara Reflection attack, and another totally unrelated truncated differential attack by Courtois and Misztal. It is hard to imagine that there could be any relationship between two so remote attacks which have nothing in common. However, there is one: Very surprisingly, both properties can be combined and lead the fastest a...
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 ...
