摘要: Digital signatures usually serve as irrefutable cryptographic evidence to support dispute resolution in electronic transactions. Trusted time-stamping and certificate revocation services, although very costly practice, must be available prevent big loss due compromising of the signing key. In this paper, we employ a revocation-free public-key framework improve efficiency maintaining validity digital non-repudiation evidence. The new PKI allows an end user control his own enables verification without retrieving information from CA. Based on PKI, could validate generic using TSA only. Moreover, forward-secure TTP’s involvement.
