Cryptanalysis of GOST R hash function ?
The first cryptanalytic results on GOST R hash function are given. We achieve collision attacks on the reduced round GOST R compression function using rebound technique. A limited birthday distinguisher on 10 rounds GOST R compression function is presented. A k-collisions on 512-bit version of GOST R is constructed.
