Proxy-based Multi-party Fair Exchange Signature Scheme
摘要
Abstract
A multi-party fair exchange protocol allows parties to exchange items in a fair way,which means that all of the parties obtain the other’ s items or neither party does. A novel protocol for multi-party fair exchanging signature without a Trusted Third Party ( TTP) is proposed. In this protocol,participants exchange their warrants firstly. Then,each participant is able to sign a proxy multi-signature on behalf of its opponents. Owing to the proxy multi-signature’ s characteristics,the scheme achieves the desired effect of multi-party fair exchange of digital signatures. Besides,the principle of it can be used at both 1-to-n and n-to-n multi-party fair exchange signature protocols. Differing from existing fair exchange schemes,the scheme can be realized without the use of a TTP,which makes it more prac-tical.关键词
