Research of modern digital signature methods

Abstract

The paper focuses on the research on modern digital signature methods, focusing on traditional RSA, EL Gamal, proxy, and multiple signatures. Based on the encryption systems of finite field polynomials, and combined with the difficult problems of integer factorization and discrete logarithm, the RSA-EL Gamal encryption and signature schemes are proposed. The introduction of RSA public keys and hash functions enhances the efficiency and security.
