| Abstract: | Objective-To improve the efficiency and security of proxy signature schemes based on elliptic curves. Methods -Having analysed and studied Hwang et al＇s proxy signature scheme and their improvement scheme, we found some problems in these schemes, such as binding in the proxy certificate and transporting secret sharing problems. Results -We proposed a proxy multi-signature scheme based on the elliptic curve. Conclusion- The new proxy signature scheme overcome the lack of Hwang et al. ＇s, achieve the secret transmission of common channels and improve the security of proxy signature scheme. |
