摘要
描述了椭圆曲线消息恢复(ECMR)签密方案,指出了其潜在的安全漏洞,即不具有前向安全性和公开验证性。为了克服上述漏洞,对ECMR签密方案的签密算法进行了改进,提出了一种新的签密方案。通过对新方案的安全性进行分析后表明,新方案有效地弥补了原方案的不足。
The paper described the elliptic curves message recovery (ECMR) sigocryption scheme and discovered potential security prob)em.EOMP, signcryption scheme do not have forward security and public verifiability.Based on this,the paper made an improvement on solution and proposed a new signcryption scheme.The analysis shows that the new signcryption scheme meets security requirements and makes up for the deficiency.
