Abstract. We introduce VSH, very smooth hash, a new S-bit hash function that is provably collision-resistant assuming the hardness of finding nontrivial modular square roots of ver...

Recent collision-finding attacks against hash functions such as MD5 and SHA-1 motivate the use of provably collision-resistant (CR) functions in their place. Finding a collision ...

In [ZMI89,ZMI90] two constructions for a collision resistant hash function were proposed. The first scheme is based on a block cipher, and the second scheme uses modular arithmetic...
