Title:
Strongly Secure Authenticated Key Exchange from Ideal Lattices

Authors: Xiaopeng Yang, Wenping Ma

Abstract:

In this paper, we propose an efficient and practical authenticated key exchange (AKE) protocol from ideal lattices, which is well-designed and has some similarity to the HMQV protocol. Using the hardness of the graded discrete logarithm (GDL) problem and graded decisional Diffie-Hellman (GCDH) problem, the proposed protocol is provably secure in the extended Canetti-Krawczyk model.
