A communication device and communication method

Abstract

A communication device and a communication method are disclosed. The communication device includes: a copyright verification module, which is used to process and calculate a detection signal to obtain a control signal, and obtain authorization verification data by verifying the legality of copyright, and the authorization verification data includes authorized legal data; a control module, configured to receive a control signal sent by the copyright verification module, and output an execution signal; and an operation module, connected to the copyright verification module and the control module, for receiving the authorization After the legal data is obtained, the control signal is processed and then output to the control module. The communication device of the present application uses the copyright verification module with encryption and verification functions to process the detection data and verify the validity of the copyright, instead of directly processing the detection data through the control module, so as to ensure the security of data transmission and improve the security of the entire communication device. confidentiality.

Description

technical field [0001] The present invention relates to the technical field of information security, in particular to a communication device and a communication method. Background technique [0002] Industrial control system (Industrial control system, ICS) is a general term for various control systems, which are widely used in various fields such as electric power, natural gas, chemical industry, basalt new materials, petroleum, etc., including master stations, networks and substations. The basic working principle of the industrial control system is that the sub-station collects the measurement data of the industrial process and sends the data to the main station through the network. Executes an action and returns the execution result and / or status to the master. [0003] Due to the harsh computing environment of industrial control system applications, not only are there many network communication methods, but also the equipment is completely exposed to the open computing ...

Problems solved by technology

However, in the electronics industry, for the protection of hardware systems, packaging PCB wiring, product development technology, etc., general encryption authentication sends a random plaintext to the encryption chip when it is turned on, and the encryption chip returns the ciphertext after matching and then proceeds. Work, and will not judge again later, such encryption is not strong, it is easy to be cracked by crackers

Moreover, in order to quickly realize some commonly used functions (monitoring, operation, recording, redundancy, etc.), new projects are usually developed through secondary development using mature industrial control systems on the market. Then the system's control algorithm, process control, formula and other technologies It is often mastered by the staff of these integrated systems, and possible leaks may bring security risks to new technologies. At the same time, the industrial control system itself is fragile, and the process data and formula data carried by it may cause uncertainty due to the uncertainty of operation and maintenance behavior. Security risks, low level of information protection
