Cryptanalysis of GOST R Hash Function

Hash functions are taking important roles in cryptography and have been used in many applications, e.g., digital signatures, authentications and message integrity. Since the break of MD5 and SHA-1, cryptographers have been searching for secure and efficient hash functions. Developed from GOST, GOST R is the hash function standard of Russia. Similar as the structure of whirlpool, it also uses an AES-like block cipher in its compression function. Rebound attack is a freedom degrees utilized technique which can be applied to find collisions in both permutation based and block cipher based hash constructions.
