Abstract
A safety management and control system for full lifecycle of industrial control data, comprising: an administrator terminal holding an administrator public-private key pair and an administrator public key root certificate; a server comprising an encrypted database kernel and an initializer, the encrypted database kernel is located in a trusted execution environment and contains industrial control data; the initializer is configured to initialize the encrypted database kernel in combination with the administrator public key root certificate sent by the administrator terminal when the server is deployed for the first time, and return a self-signed certificate generated by the server to the administrator terminal; and a client that accesses the system through the certificate issued by the administrator terminal, and interacts with the server for industrial control data within the authority configured by the administrator terminal.
