短群签名的高效批验证

进入普适通信的时代，从车辆到心脏监听器等大量设备都需要与它们的环境彼此交流信息，从而对验证和安全通信的要求不断上升：①密码费用较低；②能够快速验证大量不同来源的消息；③隐私保护。文章针对一个高效的短群签名体制提出了一个批验证算法，其中验证运算的主要部分只需要2个双线性对，就可满足上面的全部3个要求。

Batch Verification of Short Group Signatures

As pervasive communication becomes a reality, everything from vehicles to heart monitors constantly communicates with their environments, the need for authentication and secure communication grows. For instance, several applications require that cryptographic overhead be low and that many messages from many different signers be verified very quickly, and moreover be privacy friendly. This paper proposes a batch verifier for an efficient group signature scheme with a verification time where the dominant operation requires only 2 pairings.
