Abstract

Most of the existing two-party password-based Authenticated Key Exchange (2PAKE) protocols from lattices are proven secure using the indistinguishable common reference string model or the Bellare-Pointcheval-Rogaway model. This paper proposes a two-party password-based authenticated key exchange protocol based on the Ring Learning With Errors (RLWE) problem and proves its security under the Universally Composable (UC) framework. Compared with similar protocols, the new protocol achieves a higher level of security and efficiency.
