Abstract

Electronic contract is an important part of electronic commerce, and the key issue is how to ensure the fairness of contract signing. In view of some electronic contract signing protocols in the network environment can not achieve fairness completely or need the third party involved. This paper proposed a new concurrent signature in virtue of ECDSA scheme and applied it to a fair contract signing protocol. This new protocol based on ECDSA ensure the fairness of contract signing in virtue of ambiguous signatures become valid concurrently, and ensure the confidentiality of the contents of the contract without the third party involved. This protocol is applied to most electronic contract signing in network environment.
