Constant-Round Group Key Exchange from the Ring-LWE Assumption

July 14, 2019
Author(s)
Daniel C. Apon, Dana Dachman-Soled, Huijing Gong, Jonathan Katz
… there has been almost no work looking at candidate post-quantum group key-exchange protocols. Here, we propose a … problem. By applying the Katz-Yung compiler using any post-quantum signature scheme, we obtain a (scalable) protocol for authenticated group key exchange with post-quantum security. Our protocol is constructed by generalizing …
