Annotation: The proposed oblivious signature scheme 1-out-of-n messages based on the difficulty of finding isogenies between supersingular elliptic curves is a variety of Schnorr’s signature. The signature time of 10 messages takes 42,2 seconds. The signature scheme is aimed at solving problems related to maintaining privacy on the Internet.
Keywords: digital signature, oblivious signature scheme, isogeny based cryptography.
