摘要: Using the hard assumption of Ring-Decision Learning With Errors (Ring-DLWE) in lattice, a new Authenticated Key Exchange (AKE) scheme is proposed, which based on Peikert's reconciliation technique. Under standard model, proposed provably secure CK additionally achieves weak Perfect Forward Secrecy (wPFS). Compared with current (KE) schemes LWE, not only protects shared session key balanced derivation function but also resists quantum attacks because lattice problem.
