Research on verification method of electronic signature based on time-stamp service

Management functions,such as application,report of loss and so on,are the important components in electronic signature management system.Different types of units in use of electronic signature system have different characteristics.Based on analysis of management features of electronic signature in the university,a verification method for electronic signature based on the time-stamp service is put forward in this paper.The electronic signature management processes of application,report of loss,resetting,reproducing,and writing off are researched deeply.A method based on time-stamp service to solve the verification problems under different electronic signature processes is proposed.Finally,the feasibility of this project is verified through actual electronic signature application system for the university-oriented internal documents management.
