Title:
Hashing into quadratic residues modulo a safe prime composite
Authors: Sietse Ringers
Abstract:For n = pq a product of two safe primes, we construct and prove security of a cryptographic hash function H mapping into the square residues QR_n \subset (\mathbb{Z}/n\mathbb{Z})^*, by squaring the output of an ordinary cryptographic hash function H of sufficiently long output.
