Tao Long and Xiaoxia Liu

Full text: PDF


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.
