摘要: Timestamping is a cryptographic technique providing us with proof-of-existence of digital document at given time. Combining both signature and provable time-stamping guarantees authentication, integrity non-repudiation electronic documents. In this paper, we introduce such service, so called signtiming. Our scheme based on an ID-based aggregate secure in the random oracle model.
