Electronic transactions with commercial values between two business parties may want to be legally bound. Digital signature is an important security mechanism to provide evidence regarding the status of a transaction. However, evidence solely based on digital signatures may not enforce strong non-repudiation. Additional mechanisms are required to make digital signatures as valid non-repudiation evidence in the settlement of possible disputes. The conventional approach is to invoke a time-stamping service from a trusted third party. But it may become hard to deploy B2B applications in which no on-line third party is involved. In this paper, we present an efficient mechanism for maintaining the validity of digital signatures in direct B2B applications without the involvement of a trusted third party.
