Management method and system of national standard electronic seal

Abstract

Embodiments of the invention provide a management method and system of a national standard electronic seal. The method mainly comprises the following steps: a client side fills electronic seal data with a HASH value of a to-be-signed original data, generates preprocessing seal data, and transmits the preprocessing seal data to a server through a safety transmission channel; the server fills the preprocessing seal data with server seal time and a server signature, and transmits the preprocessing seal data filled with the server seal time and the server signature to the client side through the safety transmission channel; and the client side fills the preprocessing seal data, transmitted by the server, with user signature information, and transmits the preprocessing seal data, filled with the user signature information, to the server. The management method and system of the national standard electronic seal effectively solve the problem that a user can forge the seal time on the condition that only a user signature is possessed, and solve the problems that the server forges user seal information on the condition that only the server signature is possessed, and repudiation cannot be effectively prevented. So safety of an electronic seal system is guaranteed on a password level.

Description

technical field [0001] The invention relates to the technical field of electronic signatures, in particular to a management method and system for national standard electronic signatures. Background technique [0002] With the continuous acceleration of the informatization process, more and more enterprises and institutions adopt electronic office, and traditional paper documents are gradually replaced by electronic documents. The widespread use of electronic contracts and electronic documents has brought great convenience to information-based office. However, since electronic documents are easy to be copied and tampered with, how to ensure the authenticity, integrity and non-repudiation of electronic documents has gradually become an information A very important security issue for the development of globalization. Electronic signature products appear to solve the above problems, and electronic signature products effectively guarantee the security of electronic document appl...

AI Technical Summary

Problems solved by technology

[0005] The shortcomings of the above-mentioned national standard electronic signature standard of the prior art are: the client holds the user's private key, and the client can forge the current stamping time; the server holds the user's private key, and the validity of the sealer's signature cannot be guaranteed. There is a possibility that the signature of the sealer may be forged by the server
