Abstract: A fair exchange protocol is the most basic tool for constructing an E-Commerce system.BLS short signature is one of the cryptographic primitives most widely used in pairing-based cryptography.An optimistic fair exchange protocol based on BLS signatures is proposed.The security and efficiency of the new scheme are analyzed.

Key words: BLS signature, fair exchange protocol, bilinear pairing

摘要: 公平交换协议是构造电子商务系统的最基本工具。BLS短签名是双线性密码学中应用最为广泛的密码元件之一。基于BLS短签名,提出了一种优化公平交换协议,并分析了其安全性与运行效率。
