Embodiment Construction

[0047] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0048] Such as figure 1 As shown, an expected value management method based on trusted computing and digital certificate technology, the method includes the following steps:

[0049] Such as figure 2 As shown, (1) generate a CA certificate; said step (1) includes, the management center obtains the public key of the user and takes the public key as a parameter, applies for a certificate request to the offline CA center, and saves the CA certificate after the application is successful. CA center, also known as CA organization, is the certificate authority center. Its main function is to generate, update and verify certificates. It is a trusted third party in transactions and undertakes the responsibility of verifying the validity of public keys in the public key system.

[0050] Such as image 3 As shown, (2) obtain th...

Abstract

The invention relates to a trusted computing and digital certificate technology-based expected value management method. The method comprises the following steps: generating a CA (Certificate Authority) certificate; acquiring signature software according to the CA certificate; detecting the signature software; performing expected value processing on the verified signature software by using a management center. Thus, the normalization of a software package installing process of a power production control type system terminal is guaranteed, the management center can timely learn the condition of the software package installed on the terminal, and further the consistency and the safety of the source of the software package installed on the terminal is guaranteed.

Description

technical field [0001] The invention relates to a management method, in particular to an expected value management method based on trusted computing and digital certificate technology. Background technique [0002] The power production control system uses PKI / CA to build a security certification system to ensure the reliability and confidentiality of data. The digital certificate system is divided into multiple levels. The upper-level certificate system issues certificates for the lower-level certificate system. The certificate issuance methods are all imported offline. [0003] The basic function of digital certificates is to identify the identities of users, processes, and services in power production control systems, and it is realized through the combination of digital certificates and role certificates. The digital certificate uses USB-KEY as the carrier of the certificate, and currently supports the commercial secret SM2 algorithm. [0004] Digital certificates are t...
