It can be used to show some secret lies in a specific range without leaking the secret itself. The problem is that the range is public information. Everyone can easily pick a number in the range and claim that the number belongs to the user. Because of the zero-knowledge property, no one can challenge the proof generated from a fake number. To solve this problem, we integrate a signature service with the zero-knowledge proof protocol. Before a prover generates a proof, a trusted-third party needs to create some authenticated primitives, which are related to the message, for the proof generation. So a verifier can check if the proof is authenticated before accepting the proof. We believe that proposed Authenticated Zero Knowledge Range Proof can be beneficial to many applications in the world.零知識證明已認證證明範圍證明Zero­-Knowledge ProofAuthenticated ProofRange Proof學術論文
