MCSI: A Masked Commutative Supersingular Isogeny Key Exchange with Blinded Ephemeral Keys

We introduce MCSI, a two message key exchange we design over the CSIDH class group action, in which each party sends its ephemeral public element under an authenticated encryption keyed by the value the two static keys determine. The design gives implicit mutual authentication, hides the ephemera...
