Two-party authenticated key exchange protocol using lattice-based cryptography
Xiaopeng Yang and Wenping Ma
Abstract
Authenticated key exchange (AKE) protocol is an important cryptographic primitive that assists communicating entities, who are communicating over an insecure network, to establish a shared session key to be used for protecting their subsequent communication. Lattice-based cryptographic primitives are believed to provide resilience against attacks from quantum computers. An efficient AKE protocol with smaller module over ideal lattices is constructed in this paper, which nicely inherits the design idea of the excellent high performance secure Diffie-Hellman protocol. Under the hard assumption of ring learning with errors (RLWE) hard assumption, the security of the proposed protocol is proved in the Bellare-Rogaway model.
