Open publisher page 0 citations

Abstract

Non-repudiation is one of the most important premises to achieve electronic commerce while fairness is what people have been chasing during electronic transaction. In this paper we propose a fair non-repudiation protocol to resolve the possible repudiation problem both in sender side and in receiver side and make them in equal positions. In the protocol, a trusted third part is used to generate non-repudiation evidence and the number of exchanged messages is smaller. This protocol can achieve non-repudiation service in an efficient and practical way.
