Distributed Smooth Projective Hashing and its Application to Two-Server PAKE
Franziskus Kiefer and Mark Manulis
Abstract
Smooth projective hash functions have been used as building block for various cryptographic applications, in particular for password-based authentication. In this work we propose the extended concept of distributed smooth projective hash functions where the computation of the hash value is distributed across $n$ parties and show how to instantiate the underlying approach for languages consisting of Cramer-Shoup ciphertexts. As an application of distributed smooth projective hashing we build a new framework for the design of two-server password authenticated key exchange protocols, which we believe can help to "explain" the design of earlier two-server password authenticated key exchange protocols.
