A method and device for safe production of electronic certificates

Abstract

The invention discloses an electronic license safety production method and device. According to the scheme, on the basis that license information is stacked on a license template to form a visual license version, corresponding non-license information is stored on the non-license information region of the license according to categories; on the basis, classified digital signing and encrypting are performed on the corresponding license information in the formed electronic license. The formed electronic license generation scheme can be generally suitable for generation of electronic licenses under different industries and different scenes, and the confidentiality and safety of the electronic license are ensured through classification encryption and signature mechanisms.

Description

technical field [0001] The invention relates to information security technology, in particular to the production technology of electronic certificates. Background technique [0002] At present, at the national level, the electronic certificate library is defined as a type of basic library. Under the demonstration application and promotion of electronic certificates in various industries, the application security of electronic certificates has received more and more attention, and has also attracted more and more attention. Authenticity, security, reliability and practicality are particularly important. [0003] For the generation of electronic certificates, the currently commonly used method is to synthesize an electronic document by superimposing the face-to-face information on the certificate template, that is, an electronic certificate, or to affix the seal of the issuing authority on the certificate template and then superimpose the face-to-face information to synthesize...

AI Technical Summary

Problems solved by technology

The existing common practice of generating electronic certificates is the same, and its security is low and its practicability is not strong:

[0004] On the one hand, there is a lack of protection for the authenticity of electronic certificates. If there is no issuing authority to view the information on the certificate (the electronic document formed after the certificate template is superimposed with the face-to-face information, it does not contain the source data information, expansive information, hidden information, and management of the certificate. information and digital signature information, etc.), license source data, digital signatures of extended information and management information, and digital signatures of hidden information without a certificate holder;

[0005] On the other hand, there is a lack of confidentiality protection for private information in electronic certificates, such as encryption protection and authorized access control for hidden information as a certificate holder, and encryption protection and access control for administrative information as an issuing agency. ;

[0006] On the other hand, the practicability of electronic certificates is not strong. For example, electronic certificates do not have the functions of classifying and storing certificate source data, expansive information, hidden information, and management information.

[0007] In addition, although there are certain differences in the technical routes of the production and production of existing electronic certificate products, the common practice is to protect the digital signature mechanism based on all information. The protection mechanism of digital signature cannot adopt the technical bias of classifying and protecting the internal information of the license
