Multi-Collision Resistance: A Paradigm for Keyless Hash Functions
hash functions zero knowledge succinct arguments
2017/6/1
We study multi-collision-resistant hash functions --- a natural relaxation of collision-resistant hashing that only guarantees the intractability of finding many (rather than two) inputs that map to t...
Multi Collision Resistant Hash Functions and their Applications
collision resistant hashing entropy approximation
2017/6/1
Collision resistant hash functions are functions that shrink their input, but for which it is computationally infeasible to find a collision, namely two strings that hash to the same value (although c...
