FPGA-based information security maintenance method

Abstract

The invention belongs to the technical field of industrial control systems, and particularly relates to an FPGA-based maintenance information security method. According to the technical scheme, the FPGA-based maintenance information security method can strengthen data security of a distributed control system (DCS) and an engineer station, encrypt and sign communication, and ensure that the controlsystem can still normally and reliably operate when receiving malicious attacks.

Description

technical field [0001] The invention belongs to the technical field of industrial-grade control systems, and in particular relates to an FPGA-based method for maintaining information security. Background technique [0002] With the wide application of computer systems and other digital devices in the industrial field, especially the deep integration of informatization and industrialization and the rapid development of the Internet of Things, the network, informatization and intelligence level of power monitoring system products have been further improved. With the development of computer and network technology, power monitoring system products connect to public networks such as Internet+, threats such as viruses and Trojan horses are spreading to electrical systems, security incidents in power industry systems have increased significantly, and the number of system security vulnerabilities has continued to increase. As an important part of the power system, nuclear power plan...

Problems solved by technology

[0003] There is a big difference between the information security of the power industry and the traditional information security, and the level of nuclear power safety technology and protection capabilities is still in its infancy, causing the electrical monitoring system of nuclear power plants to face greater information security risks than before, and the security situation is severe. In the nuclear power plants in service and under construction, there are no effective protection measures for the electrical system and information security in the whole life cycle, and the information security protection capability is weak
