Rank AGS Identification Scheme and Signature Scheme

The identification protocol is a type of zero-knowledge proof. One party (the prover) needs to prove his identity another verifier) without revealing the secret key verifier. can apply Fiat–Shamir transformation convert an scheme into signature which be used for achieving security purposes and cryptographic purposes, especially authentication. In this paper, we recall protocol, namely RankID scheme, show that incorrect insecure. Then, proposed more natural approach construct rank version AGS our construction overcomes flaws in scheme. Our proposal achieves better results when comparing public size, size with existing schemes, such as Rank RVDC CVE schemes. also 90%, 50%, 96% reduction compared
