Research Of Information Security Solutions Of Industrial Control System Based On Trusted Computing

The popularity of network technology is convenient for the production and life of people, while the hidden safety danger, even disasters resulted from information opening are becoming more and more prominent. Normal operation of industrial infrastructure is the guarantee of stability of the national economy and people’s normal life, and information security of industrial control system is the basis of the normal operation of industrial infrastructure, so it is significantly important to make industrial control system operate stably and its information security issues are not allowed to be ignored. Global network attack has changed slowly from stealing information of information system to hitting devastatingly the key infrastructure that is vital to the national economy and the people’s livelihood, which is a serious threat to the industrial control system that is related to industrial production, national economy, national security and people’s life and property. Therefore, it is urgent to solve the information security faced by industry control system.The information security problems of industrial control system is studied deeply in this paper based on the architecture of industrial control systems. And a kind of solution to information security of industrial control system based on trusted computing is put forward.Firstly, the trend of information security of industry control system is known from the layer of current national regulation and industrial control vendor at present, and prospect development is mastered from theoretical research. Then the vulnerability of the architecture of industrial control system is dug and compared to the characteristics of information security of IT information system. Finally, data from information security of industrial control systems is collected to analyze the main threat and attack ways and means which are the industrial control system is facing.Secondly, a solution to information security of the industrial control system is proposed based on trusted computing, according to the principle of trusted computing and trusted connection, the characteristics of information security of industrial control system, pros and cons of existing defensive measures discussed in this paper, and analysis is carried on in the Supervisory Control And Data Acquisition (SCADA).Finally, Through the simulation of trusted computing platform, the integrity measurement and remote proof of the main technical means of the scheme are realized. Then the advantages and disadvantages of the solution are analyzed according to experimental procedure and results.The solution to information security.of the industrial control system based on trusted computing realizes the linkage between the inside firewall of industrial control systems, the intrusion detection system and the trusted connection server, and make the information fusion of network security devices and improves the overall defense capability of industrial control systems at last. In addition, the trusted computing platform based on the characteristics of hardware defense overcomes the common problem of the traditional firewall, virus killing and vulnerability scanning pure software that are less efficient and easily cracked, and improves security of industrial control system.
