> 中文摘要: 为了满足广播环境下通信数据的机密性和认证性需求以及消息收发双方的匿名性,提出了基于身份的多接收者匿名混合签密机制,满足收发双方的匿名性保护需求,并且接收者具有解密独立性.正确性分析及安全性证明表明,该机制是安全、有效的多接收者匿名混合签密机制.相对于现有方案,除了具有保密性和不可伪造性之外,该机制具有更优的性能,如更高的匿名性、公开验证性等.将该机制改进后,提出了具有收发双方匿名性、公开验证性、不可否认性等安全属性的多接收者多消息混合签密机制,实现了广播通信环境下用户的多消息发送需求.
Abstract:Authentication and confidentiality, as well as sender and receiver anonymity are essential in broadcast communication. In this paper, an anonymous hybrid signcryption scheme with multi-receiver is proposed using identity-based cryptography. The proposal does not contain receiver's identity list, and the identity of sender is included in an identity set. Thus, it not only obtains the receiver's anonymity, but also achieves the sender's anonymity. Additionally, the proof of security and the analysis of correctness demonstrate that the scheme is secure and effective. Compared with the pre-existing schemes, the proposal enjoys better performances in many perspectives, including confidentiality, unforgeability, higher anonymity of sender and receiver and public verifiability. Moreover, the presented method can be improved to develop an efficient construction of hybrid signcryption scheme with multi-message and multi-receiver, which can obtain these security properties, such as sender and receiver anonymity, public verifiability and non-repudiation. Finally, the new variant can achieve the requirement of sending multi-message in broadcast communication.
