Data processing method and device, electronic equipment and storage medium

Abstract

The embodiment of the invention provides a data processing method and device, electronic equipment and a storage medium. The method comprises the steps that a first process containing a first name and a first password is created; when the first process runs, the first name and the first password are written into the TCM through a drive program of the TCM; when a CA certificate or a secret key associated with the embedded device needs to be stored or read in the TCM, a second name and a second password provided by a second process are verified; the method also includes: under the condition of successful verification, determining a first entry number related to the CA certificate or the secret key; storing the CA certificate or key in the TCM based on the first entry number, or obtaining a second entry number provided by the second process, and reading the CA certificate or key in the TCM based on the second entry number, wherein the first process is the same as or different from the second process.

Description

technical field [0001] The present invention relates to the field of data security, in particular to a data processing method, device, electronic equipment and storage medium. Background technique [0002] In the field of smart devices in power systems, we often face the problem of safe storage of root certificates and private keys of certification authorities (CA, Certification Authority). The current common solution is to store them in the file system and perform security isolation through the user permissions of the operating system. This scheme cannot fundamentally guarantee security. Contents of the invention [0003] In view of this, the main purpose of the present invention is to provide a data processing method, device, electronic equipment and storage medium, which can at least partly solve the above problems. [0004] In order to achieve the above object, technical solution of the present invention is achieved in that way: [0005] In a first aspect, an embodim...
