Abstract

The invention discloses a digital certificate offline authentication system and method, which are applied to a user terminal, a console, and a server connected sequentially in an offline network environment. The system includes: the user terminal, which is used to send The digital certificate is requested to the server; the server is used to verify the digital certificate request and generate a key corresponding to the digital certificate request; issue a digital certificate according to the key and the digital certificate request to the console; the console is used to write the digital certificate to the user terminal. In this way, the security risks brought by the issuance of digital certificates on the external network are avoided, and at the same time, the cumbersome operations brought by the traditional copying of digital certificates through U disks are simplified and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of data security, in particular to a digital certificate offline authentication system and method. Background technique [0002] With the State Grid Corporation's construction of a unified smart grid featuring informatization, automation, and interaction, network access has become increasingly complex, with higher information integration and better user interaction. The business system has stored a large number of people. , financial, material and other key information. In order to ensure the information security of business data, it is necessary to strengthen the construction of security infrastructure such as identity authentication systems, and deepen research and application in terms of secure access, secure transmission, and secure applications. [0003] Among them, the communication method between the industrial terminal and the industrial control master station is mainly key communication based on IP...
