Abstract: This paper proposes an identity based signcryption scheme with both public verifiability and forward security using bilinear pairings.The scheme can separate the signature verification from message recovery.It can be applied in mobile E—business scenario,such as filtration of bad instant messages of mobile equipment.The proposed scheme is proved to be secure assuming the bilinear Diffie-Hellman problem is hard.This scheme is also very efficient regarding the computation costs and the communication overheads after analyzing and being compared with other schemes.

Key words: signcryption, ID-based, bilinear pairing, random oracle model

摘要: 利用双线性对提出一个满足公开验证性和前向安全的基于身份的签密方案,并且能够将签名的验证和消息的恢复分别独立进行,可以应用于为移动设备过滤垃圾信息等移动电子商务场合。在BDH问题是困难的假设下用随机预言模型给出了安全性证明,经过分析比较,该方案具有很高的安全性和效率。
