Digital signature method and system of USBKEY equipment

Abstract

The application provides a digital signature method and system of USBKEY equipment, and belongs to the technical field of an electronic signature. The method comprises, after the USBKEY equipment receives a signature instruction from a client side at the first time, a recorded key state is to be idle; the USBKEY equipment continuously monitors a user key and updates a user key state, and, after the USBKEY equipment receives the signature instruction at the first time or at a subsequent time, the recorded key state is determined, residual time of the user key is obtained and is fed back to the client side on the condition that the recorded key state is idle, and, on the condition that the key state is not idle, corresponding signature operation is executed, and a signature result is fed back; and, if the client side receives the signature result, a flow is ended, and, if the residual time fed back by the USBKEY equipment is received, the signature instruction is sent to the USBKEY equipment on the condition that the residual time is not zero, and the flow is ended when the residual time is zero. According to the scheme, clock synchronization of the client side and the USBKEY equipment is achieved on the condition that a system load is low, and user experience is improved.

Description

technical field [0001] The present application relates to the technical field of electronic signatures, in particular to a digital signature method and system for a USBKEY device. Background technique [0002] In order to ensure the safety and authenticity of information, some documents require the signature or seal of the parties, so that the two parties in the information exchange can identify the authenticity of the document. At present, some paper documents require handwritten signatures to prove their authenticity. For documents expressed and transmitted in the form of electronic documents, traditional handwritten signatures and stamps cannot be performed, and electronic signature technology is required. Currently, countries generally adopt One of the electronic signature technologies is digital signature technology. With the development of Internet and electronic communication technology and the emergence and continuous optimization of USBKEY technology, USBKEY used t...

AI Technical Summary

Problems solved by technology

However, the existing technology does not consider the problems caused by the inconsistency between the USBKEY and the client clock. For example, the client still displays the remaining time, but the USBKEY device thinks that it has timed out. At this time, even if the user presses the confirm or cancel key, it will not There should be a response, and the user experience is poor
