چکیده
|
In this paper, we describe an attack on a new double block length hash function which was proposed as a variant of mdc-2 and mdc-4. the vmdc-2 compression function is based on two calls to a block cipher that compresses a 3n-bit string to a 2n-bit one. this attack is based on the joux's multicollision attack, where we show that an adversary wins nding collision game by requesting 2^70 queries for n = 128-bit block cipher that is much less than the complexity of birthday attack.
