摘要: 通过在Schnlorr签名方案中利用秘密分享技术,给出了一种新的公平交易方案。该方案的公平性和安全性依赖于多个可信任第三方(TTP)。由协议的公平性和安全性分析可知,它比那些单纯地依赖于一个可信任第三方的公平交易方案具有更好的安全性和可靠性。

Abstract: By using the secret sharing technique in the Schnorr signature scheme, a new scheme of fair exchange protocol is proposed, whose fairness and security depend on two or more trusted third authorities. According to the security and fairness analysis of this protocol, compared with the fair exchange protocols that fully depend on only one TTP, the proposed protocol is more secure and reliable.
