| 摘 要： | 为了满足群组之间相互通信时同时需要加密和认证的要求,设计了一个基于椭圆曲线密码体制的广义门限签密方案,该方案能够同时实现,门限签密和,门限共享解签密。在门限共享解签密阶段,利用Chaum-Pedersen离散对数等式知识证明协议的思想实现了对群组成员中恶意成员的检测。通过对该方案进行的安全性分析和效率分析结果表明,该方案可以用较小的计算代价和通信代价安全地实现群组通信中的保密和认证。

| Abstract: | Tomeet the needs of both encryption and certification for the group communication,a generalization of threshold signcryption scheme based on elliptic curve cryptosystem is given.The scheme can simultaneously achieve,threshold signcryption and, threshold shared unsigncryption.In threshold shared unsigncryption,the scheme realizes the detection of the malicious members of the group's number by use of Chaum-Pedersen knowledge proof protocol of discrete logarithm equality.By analyzing the security and efficienc... |
