Finding collisions for MD4 hash algorithm using hybrid algorithm
The modification of message that meets the sufficient conditions for collision is found in the last step of differential attack proposed by Wang et all. (2005) on MD4 hash algorithm. Here we show how this attack phase, finding a collision starting from the list of sufficient conditions for the collision, can be implemented using a combination of two algorithms evolutionary algorithm and hill cl...
متن کاملAn Improved Hash Function Based on the Tillich-Zémor Hash Function
Using the idea behind the Tillich-Zémor hash function, we propose a new hash function. Our hash function is parallelizable and its collision resistance is implied by a hardness assumption on a mathematical problem. Also, it is secure against the known attacks. It is the most secure variant of the Tillich-Zémor hash function until now.
متن کاملCollisions for Hash Functions MD4, MD5, HAVAL-128 and RIPEMD
1 Collisions for MD5 MD5 is the hash function designed by Ron Rivest [9] as a strengthened version of MD4[8]. In 1993 Bert den Boer and Antoon Bosselaers [1] found pseudo-collision for MD5 which is made of the same message with two different sets of initial value. H. Dobbertin[3] found another kind of collision which consists of two different 512-bit messages with a chosen initial value 0 V I ′...
متن کاملCryptanalysis of the Hash Functions MD4 and RIPEMD
MD4 is a hash function developed by Rivest in 1990. It serves as the basis for most of the dedicated hash functions such as MD5, SHAx, RIPEMD, and HAVAL. In 1996, Dobbertin showed how to find collisions of MD4 with complexity equivalent to 2 MD4 hash computations. In this paper, we present a new attack on MD4 which can find a collision with probability 2−2 to 2−6, and the complexity of finding ...
