Recent attacks on standard hash functions call the paradigm into question. It is well known that a simple modification of the hash-and-sign paradigm may replace the collision-resistant hash with a weaker primitive—a target-collision resistant hash function (also known as a universal...
Collision resistance is related tosecond preimage resistance, which is also known as weak collision resistance. A minimal requirement for a hash function to be collision resistant is that the length of its result should be 192 bits (in 2011). Collision resistance is the defining property of a c...
The subject of this thesis is the study of collision resistant hash function. A cryptographic hash function is one of the cryptographic primitives designed to protect theintegrity of data such as that in digital signatures and online business transactions. Popular hash functions are Message Digest 4...
Elliptic curve hash functions are provided which do not require a pre-existing hash function, such as that required by the MuHash. The elliptic curve hash functions can be built from scratch and are collision free and can be incremental. In one embodiment, rather than a pre-existing hash fun...
Collision-resistant hash function A hash function is a function that compresses an input message of arbitrary length into an output with short and fixed length:h=(h1h2…hq)=H(M),M=(m1m2m3…mp),p≫q,where H represents the operation that maps a message M of arbitrary length p bits to...

Chameleon-hash functions, introduced by Krawczyk and Rabin (NDSS’00), are trapdoor collision-resistant hash functions parametrized by a public key. I
A t -multi-collision-resistant hash function ( t -MCRH) is a family of shrinking functions for which it is computationally hard to find t distinct inputs mapped to the same output by a function sampled from this family. Several works have shown that t -MCRHs are sufficient for many of...
