A Supersingular Isogeny-Based Ring Signature
[article]
2021

A ring signature is a signature scheme that provides the authenticity of a message anonymously. In this paper, we first present a post-quantum sigma protocol for a ring that relies on the supersingular isogeny-based interactive zero-knowledge identification scheme proposed by De Feo, Jao, and Plût in 2014. We prove the correctness, 2-special soundness and honest-verifier zero-knowledge properties of the proposed protocol. Then, we construct a ring signature from the proposed sigma protocol for
