Abstract: We present several new constructions of collision-resistant
hash-functions (CRHFs) from general assumptions. We start with a simple
construction of CRHF from any homomorphic encryption. Then, we
strengthen this result by presenting constructions of CRHF from two
other primitives that are implied by homomorphic-encryption: one-round
private information retrieval (PIR) protocols and homomorphic one-way
commitments. (Update)
