Industrial control system safe support framework and data safe transmission and storage method thereof

Abstract

The invention discloses an industrial control system safe support framework and a data safe transmission and storage method thereof. The safe support framework comprises a plurality of safe servers provided with safe chips, and a plurality of clients provided with safe chips, wherein the clients and the safe servers are in connection over the network; the servers are provided with an industrial control system credible environment control platform server, a credible mobile medium control system server, a credible industrial control firewall server and a credible database system; the clients are provided with a credible industrial control system firewall client, a credible environment control platform client, and a credible mobile medium control system client, wherein the credible database system is responsible for providing confidentiality and integrity protection service for the setting sensitive data stored in a database, and binding the setting sensitive data with a credible industrial control system environment. The framework and the data safe transmission and storage method thereof can prevent malicious codes from operating and broadcasting in an industrial control environment, and meanwhile avoid sensitive data leakage and tampering.

Description

technical field [0001] The invention proposes an industrial control system security support frame and a data security transmission and storage method based on trusted computing technology, which belongs to the field of industrial control security. Background technique [0002] Due to the strict requirements of industrial production on the availability of industrial control systems, security operations such as upgrades, patches, or updates of anti-virus software virus databases are usually not performed in a timely manner after deployment of industrial control systems. Because the newly upgraded or updated virus and Trojan killing tool may cause damage to the system environment while killing the virus, and then cause the system to crash. Compared with ordinary IT systems, if the industrial control system is shut down for maintenance, it will have a huge impact, such as major economic losses and environmental pollution. In the industrial control system, it is usually necessar...

AI Technical Summary

Problems solved by technology

However, as mentioned above, the existing industrial control system lags behind in upgrading and patching, so it is difficult to ensure the system environment security of industrial control terminals such as engineer stations and operator stations and industrial control servers

Second, in terms of sensitive data security, due to the difficulty in ensuring the security of the aforementioned system environment, the business data stored in the database will face threats of tampering and leakage

For example, an attacker can invade the system environment and tamper with sensitive data such as process recipes stored in the database, which may cause production accidents, economic losses and even casualties

In addition, if the production plan and other data stored in the database are leaked to competitors, it will also have a huge impact on the company
