Hash Functions from Sigma Protocols and Improvements to VSH
Hash Functions Sigma Protocols VSH

We present a general way to get a provably collision-resistant hash function from any (suitable)
-protocol. This enables us to both get new designs and to unify and improve previous work. In
the fi...
VSH, an Efficient and Provable Collision-Resistant Hash Function

We introduce VSH, very smooth hash, a new S-bit hash func-
tion that is provably collision-resistant assuming the hardness of finding
nontrivial modular square roots of very smooth numbers modulo an...

In Eurocrypt 2006, Contini, Lenstra, and Steinfeld proposed a new
hash function primitive, VSH, very smooth hash. In this brief paper we offer commentary
on the resistance of VSH against some stand...
