Abstract

An one-time limited authorization mechanism based on ECDSA is proposed, which allows password-owner to grant his right to a temporary user without releasing any information about the original password and restrict the time slice or frequency easily. Based on the modification of ECDSA, the mechanism is feasible for being put into practice, can generate limited authorization password safely without being forged or re-used effectively.
