Differential 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 کاملCryptanalysis of the GOST Hash Function
In this article, we analyze the security of the GOST hash function. The GOST hash function, defined in the Russian standard GOST 34.11-94, is an iterated hash function producing a 256-bit hash value. As opposed to most commonly used hash functions such as MD5 and SHA-1, the GOST hash function defines, in addition to the common iterative structure, a checksum computed over all input message bloc...
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...
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 کاملAlgebraic Cryptanalysis of GOST Encryption Algorithm
This paper observes approaches to algebraic analysis of GOST 28147-89 encryption algorithm (also known as simply GOST), which is the basis of most secure information systems in Russia. The general idea of algebraic analysis is based on the representation of initial encryption algorithm as a system of multivariate quadratic equations, which define relations between a secret key and a cipher text...
