基于公开可验证秘密分享的公平交易协议研究

Research on Fair Exchange Protocol with Publicly Verifiable Secret Sharing

随着电子商务的发展,对公平交易的研究显得越来越重要。提出了不依赖于信任第三方,而是基于网络中成员参与的公平交易协议。其理论基础是公开可验证秘密分享原理。所有交换的信息都被加密,因而特别适合几乎没有任何物理安全性的公共网络,尤其适合基于信任分散的ad-hoc网络。

Fair exchange turns out to be an increasingly important topic due to the rapid growth of electronic commerce. A fair exchange protocol is proposed which does not rely on a trusted third party. Instead, the fairness of the protocol relies on the honesty of the neighbor participants. It is based on publicly verifiable secret sharing theory. All messages are encrypted, which makes it appealing over a large open network that has little or no physical security. This concept is therefore particularly suitable for trust distributed mobile ad - hoc networks.
