摘要:

针对Lal等人所提出的基于身份的多接收者签密方案中存在的暴露接收者身份信息隐私性和解密不公平的问题,应用拉格拉日插值方法,提出一种满足接收者身份匿名性和解密公平性的新的多接收者签密方案。基于双线性 Diffie-Hellman 问题和计算 Diffie-Hellman 问题,对随机模预言模型下的 IND-sMIBSC-CCA2 和EUF-sMIBSC-CMA的安全性进行了证明,验证本方案具有保密性和不可否认性。

关键词: 多接收者签密, 公平性, 匿名性, 保密性, 不可否认性

Abstract:

In order to solve the identify information exposure problem and the decryption unfairness problem in Lal et al’s identity-based multi-receiver signcryption scheme,a novel identity-based multi-receiver signcryption scheme,using the Lagrange interpolation method,was proposed to meet the requirements of the identity anonymity and the decryption fairness.Based on the Bilinear Diffie-Hellman and computational Diffie-Hellman assumptions,the security of IND-sMIBSC-CCA2 and EUF-sMIBSC-CMA was proved formally under the random oracle model,which shows that the proposed scheme can achieve the confidentiality and the unforgeablity required.

Key words: multi-receiver signcryption, fairness, anonymity, confidentiality, unforgeablity
