Example Embodiment

[0050] Example one

[0051] The embodiment of the present invention combines the server signature and the sealer's signature under the premise of observing the national secret standard. When verifying, the two are indispensable, effectively preventing the stamper forging the time of the signature and the server side forging the seal. Issues such as human signatures have achieved the security of signature data at the password level.

[0052] The method for managing the national standard electronic seal provided by the embodiment of the present invention includes a method for executing a seal and a method for verifying a seal.

[0053] This embodiment provides a processing flow of a method for executing a national standard electronic seal. figure 1 As shown, including the following processing steps:

[0054] Step S110: The client selects an electronic seal from the smart password key, and extracts the electronic seal data.

[0055] Step S120: The client calculates the HASH (hash) value o...

Example Embodiment

[0073] Example two

[0074] This embodiment provides a national standard electronic signature management system, and its specific implementation structure is as follows image 3 As shown, it can specifically include the following modules:

[0075] The client 31 is used to fill the HASH value of the original data to be signed into the electronic signature data, generate preprocessed signature data, and transmit the preprocessed signature data to the server through a secure transmission channel;

[0076] The server 32 is configured to fill the server stamping time and the server signature in the preprocessed signature data, and transmit the preprocessed signature data filled with the server stamping time and the server signature to the client through a secure transmission channel ;

[0077] The client 31 is also used to fill user signature information in the preprocessed signature data transmitted from the server, and transmit the final signature data filled with the user signature inf...

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...
