Two Improvements to Digital Signature Scheme Based on the Elliptic Curve Cryptosystem

Abstract—The paper outlines the importance of elliptic curve cryptosystem firstly, then analyses the using of traditional digital signature based on the elliptic curve. Due to the mod-inversion operation influencing signature and verification, thus two improvements to this point has been proposed. According to its analysis of performance, improving efficiency and ensuring security. Index Terms—elliptic curve cryptosystem, digital signature, non-inversion operation, security I.
