Abstract

Abstract: A new efficient indentity-based signcryption scheme is proposed in the paper，in which some characteristics of bilinear pairings on elliptic curves are taken into account.It has improved the drawbacks of receiver verifying signature after decrypting in the traditional signcryption scheme.Anybody can verify the signature without knowing the plaintext.The scheme is safe and also very efficient regarding the computation costs after analyzing other schemes.It can be applied in E-business scenario，such as filtration of unuseful instant messages.

Key words: signcryption, identity-based, elliptic curves, bilinear pairings

摘要： 利用椭圆曲线上双线性对的性质，提出了一种新的基于身份高效签密方案，该方案克服了传统签密体制中接收方先解密后验证签名的缺点，提供了任意第三方在不知道明文的前提下都可以验证签名的功能。经过分析比较，该方案具有很高的效率和安全性。本方案特别适用于电子商务中过滤垃圾信息等场合。
