摘　　要：论文基于椭圆曲线密码体制(ECC),对传统签密方案进行改进,设计了一个新的签密方案.分析显示,方案可以抵抗各种攻击,并能同时提供前向安全性和支持第三方验证,保证了系统的安全性和公正性;并提高了计算和通信效率.具备一定的实用价值.Based on the Elliptic Curve Cryptosystem, and by improving the traditional signcryption, this paper designs a new signcryption scheme. Analysis inditates this scheme can resist kinds of attacks, offer forward - security and third party verifica- tion, thus assuring the security and fairness of the system. In addition, the calculation and communication efficiency have been improved, so the scheme has its practical value.
