摘要

有机集成广义指定验证者签名和自认证签密的思想

提出了一个基于DLP的自认证广义指定验证者签密方案

方案的困难性基于有限域上的离散对数问题.所提方案不仅能够保护签密持有者的隐私

而且消除了证书存在问题和密钥托管问题.由于新方案具有通信代价低、计算量少和安全性强等优点

在电子商务和电子政务活动中将具有重要应用.

Abstract

By integrating the thoughts of universal designated verifier signature and self-certified signcryption

a new selfcertified universal designated-verifier signcryption scheme based on discrete logarithm problem in finite field is proposed. The new scheme can protect the privacy of the signcryption holder

moreover it eliminates certificate existence problem and key escrow problem.The proposed has the merits of low communication overheads

little computation cost and good security

so it is propitious to applications in E-commerce and E-government.
