Abstract

The present invention relates to a ModbusTCP protocol security enhancement method and system. The present invention uses the HMAC algorithm in the ModbusTCP protocol to provide identity authentication and integrity protection for the communication data of the industrial control system at the same time, and adopts the SM4 packet whose encryption and decryption speed is faster than the asymmetric encryption algorithm. The cryptographic algorithm provides confidentiality for the communication data of the industrial control system, and uses time stamps plus random numbers combined with random number set tables to prevent replay attacks at a finer granularity; on the premise of ensuring usability, the present invention comprehensively improves the industrial use of the ModbusTCP protocol. Control system security.

Description

A ModbusTCP protocol security enhancement method and system technical field The invention belongs to the ModbusTCP communication protocol technical field in the industrial control system information security field, concrete It relates to a ModbusTCP protocol security enhancement method and system. Background technique [0002] The industrial control system has been widely used in various fields such as manufacturing, transportation, water conservancy, electric power, aerospace, etc. It is closely linked with the lifeblood of our country's economy. With the development of technologies such as Industrial Ethernet and Industrial Internet, and the With the in-depth integration of information technology (IT) and operational technology (OT), the connection between industrial control systems and the Internet is becoming more and more frequent. To improve economic efficiency and achieve accurate and scientific decision-making, it is necessary to master the real-time data of t...
