MIKE: a fast and compact post-quantum NIKE
Abstract
We introduce MIKE (Module Isogeny Key Exchange), a post-quantum 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 0.65ms and the shared secret takes 4.9ms (including key validation) on a AMD CPU at 3.3GHz.
