Abstract :
The GOST hash function and more precisely GOST 34.11-94 is a cryptographic hash function and the official government standard of the Russian Federation. It is a key component in the national Russian digital signature standard. The GOST hash function is a 256-bit iterated hash function with an additional checksum computed over all input message blocks. Inside the GOST compression function, we find the standard GOST block cipher, which is an instantiation of the official Russian national encryption standard GOST 28147-89.
