Abstract
-
We give a construction of lossy projective hashing via dual projective hashing. We prove that lossy projective hashing can be converted to smooth projective hashing via pairwise independent hash functions, which in turn yields smooth projective hashing from dual projective hashing.

We propose a direct construction of lossy encryption via lossy projective hashing. Our construction is different from that given by Hemenway et al. (Eurocrypt 2011) via smooth projective hashing. In addition, we give a fully IND secure deterministic public key encryption via lossy projective hashing and one round UCE secure hash functions recently introduced by Bellare et al. (Crypto 2013).
