With the advent of the digital era, industrial control systems play an increasingly important role in the production process. However, the ensuing cyber attacks also make the security of industrial control systems face greater challenges and risks. In order to ensure the security and reliability of these real-time control systems, trusted computing technology has gradually received widespread attention and application.
Trusted computing technology refers to the problem of ensuring that the software and data in the computer system are trustworthy when used through the cooperation of hardware and software. In industrial control systems, trusted computing technology can effectively protect the integrity, confidentiality, availability and reliability of the control system, thereby improving the security and reliability of the system.
The following will introduce the application of trusted computing technology from two aspects: smart factory and smart manufacturing.
Intelligent factory aspects
The application of trusted computing technology in smart factories mainly includes the following aspects:
1. Encrypted communication based on trusted computing technology
Trusted computing technology can implement encrypted communication to ensure that the data is not attacked by unauthorized attackers or viruses during the data process and data transmission. In addition, trusted computing technology can also use digital certificates to verify identities and prevent unknown persons from intruding or tampering with data.
2. Remote access and management
Trusted computing technology can realize remote access and management, and ensure the security of data transmission through encryption technology. In this way, the factory management center and other devices can be connected securely, which enables timely and real-time access and management of factory information.
3. Trusted boot
Trusted boot refers to using hardware or software mechanisms to ensure that the system startup process has not been tampered with when the computer starts, ensuring the integrity and credibility of the system. , to avoid intrusion by unauthorized personnel or the operation of unauthorized software.
Intelligent manufacturing
In intelligent manufacturing, trusted computing technology can play the following roles:
1. Identity authentication based on trusted computing
Trusted computing technology can be used to authenticate manufacturing equipment and manufacturing processes, ensuring that only legitimate equipment and programs can run. This will protect the manufacturing process from illegal attacks and infringements, ensuring the quality and reliability of the manufacturing process and products.
2. Trusted software and programming language
Using trusted computing technology, the programming language of the software can be verified and certified to ensure that the software has no loopholes and security holes and avoid being hacked and destroyed. Those who use it. At the same time, the emergence of trusted software can unify the development ecosystem, facilitate core developers to conduct unified management of software, and improve the maintainability of software.
Summary
In smart factories and smart manufacturing, trusted computing technology plays an irreplaceable role. It not only ensures the reliability and integrity of industrial control systems, but also protects confidentiality and improves the security of industrial control systems. With the continuous development and application of trusted computing technology, I believe that future industrial control systems will be safer and more reliable.
