摘要 在已有研究的基础之上,实现了一种基于有限域上的离散对数问题(DLP)的自认证多接收者签密方案.方案避免了公钥系统中的证书存在问题和密钥托管问题,为具有多名合法接收者的签密问题提供了有效的解决途径,算法简单,安全性高,适合于在实际中应用. On the basis of existing literatures,a new self-certified multi-recipient signcryption scheme based on discrete logarithm problem(DLP) in finite field is proposed. The scheme avoids the certificate existence problem and the key escrow problem in public key cryptography and offers a efficient solution to the problem of signcryption with multi-recipient,moreover,it has simple algorithm and high security,so it is propitious to applications in practice.
