Identity Protocol Based on Zero-knowledge Proof on Conic

Abstract

A zero-knowledge proof of identity protocol on conic is proposed in this paper.The security of this protocol is based on the discrete logarithm problem on conic over finite fields.These kinds of identity protocols can be designed and implemented easier than those on elliptic curve,and faster than those based on discrete logarithm.Security and feasibility are discussed.A simple solution is proposed to a potential leak of this protocol.
