Abstract

GOST-R is a Russian Standard Cryptographic Hash function which was first introduced in 1994 by Russian Federal for information processing, information security and digital signature. In 2012, it was updated to GOST-R 34.11-2012 and replaced older one for all its applications from January 2013. GOST-R is based on modified Merkle-Damg\aa rd construction. Here, we present a modified version of GOST-R (MGR-hash). The modified design is based on wide pipe construction which is also a modified Merkle-Damg\aa rd construction. MGR is much more secure as well as three times faster than GOST-R. AES like block cipher has been used in designing the compression function of MGR because AES is one of the most efficient and secure block cipher and it has been evaluated for more than 12 years. We will also analyze the MGR hash function with respect to its security and efficiency.
