Cryptographic Hash Functions in Groups and Provable Properties

, 2011
We consider several "provably secure" hash functions that compute simple sums in a well chosen group (G,*). Security properties of such functions provably translate in a natural way to computational problems in G that are simple to define and possibly also hard to solve.

Skyscraper: Fast Hashing on Big Primes

Transactions on Cryptographic Hardware and Embedded Systems
Arithmetic hash functions defined over prime fields have been actively developed and used in verifiable computation (VC) protocols. Among those, ellipticcurve- based SNARKs require large (256-bit and higher) primes. Such hash functions are notably slow,
