N2 - We present a new framework for constructing efficient password authenticated key exchange (PAKE) protocols based on oblivious transfer (OT). Using this framework, we obtain: an efficient and simple UC-secure PAKE protocol that is secure against adaptive corruptions without erasures. efficient and simple PAKE protocols under the Computational Diffie-Hellman (CDH) assumption and the hardness of factoring. (Previous efficient constructions rely on hash proof systems, which appears to be inherently limited to decisional assumptions.) All of our constructions assume a common reference string (CRS) but do not rely on random oracles.
