A Transaction System and Method for Advance a Committed Time in the Future
A Transaction System and Method for Advance a Committed Time in the Future
The technology described in this document provides an E-commerce transaction system and a transaction method for advancing a committed time in the future. Unlike conventional E-commerce transaction technologies, this novel technology allows the validation of the signature before the committed time. The time capsule signature scheme of this invention is conducted according to an identity-based trapdoor relation. By using the identity-based trapdoor primitive, the present transaction systems and methods can distinguish whether the time capsule signature is validated before or after the committed time.
