Abstract

The invention discloses a digital certificate offline authentication system and method, which are applied to a user terminal, a console and a server side which are sequentially connected in an offlinenetwork environment, and the system comprises the following parts: the user terminal which is used for sending a digital certificate request to the server side through the console; the server side which is used for verifying the digital certificate request and generating a secret key corresponding to the digital certificate request and signing and issuing a digital certificate to the console according to the secret key and the digital certificate request; and the console which is used for writing the digital certificate into the user terminal. Therefore, the security risk caused by signing and issuing the digital certificate by the external network is avoided, the tedious operation caused by copying the digital certificate through the U disk traditionally is 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...
