Provably secure identity-based two-party authenticated key agreement protocol based on CBi-ISIS and Bi-ISIS problems on lattices

The two-party authenticated key agreement (2PAKA) protocol establishes a secure channel over the Internet between two users. This secure channel helps to transfer messages between them in the presence of an adversary. The invention of Shor’s algorithms makes current 2PAKA protocols vulnerable to quantum attacks. To mitigate quantum attacks, we designed an identity-based two-party authenticated key agreement (LB-ID-2PAKA) protocol on a lattice...
