Abstract

We introduce MIKE (Module Isogeny Key Exchange), a postquantum NIKE (Non Interactive Key Exchange) whose security relies on the CDH problem for the rank-2 Hermitian module action on supersingular elliptic curves. For NIST level 1, MIKE has very compact public keys of 80B, and using our constant time C implementation, the key generation takes 0.651ms and the shared secret takes 4.84ms (including key validation) on a AMD CPU at 3.3GHz.
