A Network Voltage Monitoring System Based on Hybrid Encryption Algorithm

Abstract

The invention discloses a network-type voltage monitoring system based on a mixed encryption algorithm, which includes a network-type voltage monitor and a host computer server. The network-type voltage monitoring instrument adopted in the present invention collects grid voltage data through a voltage monitoring module; the mixed improved encryption algorithm based on SM2 and SM4 embedded in the CPU processor encrypts the collected voltage data; the GPRS communication module encrypts the collected voltage data The processed voltage data is sent to the host computer server; the host computer server combines the network database to store, manage, evaluate and analyze the voltage data that needs to be monitored. The invention adopts the SM2 and SM4 mixed improved encryption technology approved by the State Cryptography Administration, which not only ensures the safety of the grid monitoring voltage data, but also improves the speed of voltage data encryption and decryption, and has the advantages of reducing production costs, improving efficiency and being convenient to use Advantages, can be widely used in the field of smart grid voltage monitoring.

Description

technical field [0001] The invention relates to a voltage monitoring system for monitoring voltage data of a smart grid, in particular to a network-type voltage monitoring system based on SM2 and SM4 hybrid improved encryption algorithms, belonging to the technical field of power system monitoring equipment. Background technique [0002] With the continuous deepening of electric power reform, smart grid has become the top priority in the development of electric power system. However, with the rapid development of smart grid construction, its security issues have become increasingly prominent, especially after entering the era of big data, the issues of big data security and privacy protection in smart grid have become increasingly prominent. [0003] According to the requirements of the State Grid Corporation of China and the Electricity Regulatory Commission, the power company installs a voltage monitoring device at a fixed location to continuously monitor the supply voltag...

Problems solved by technology

For example, Patent No. 201310430769.2 transmits the voltage data collected by the voltage monitoring module by means of wireless transmission such as SMS, MMS, and GPRS, and does not provide security protection for the monitored voltage data; although Patent No. 201310139854.3 uses a The voltage monitor of the chip monitors and protects the voltage data of the smart grid. However, the SM2 encryption technology adopted by the security encryption chip has the defects of complex algorithm, slow encryption and decryption of large blocks of data, and low efficiency, which is not conducive to voltage monitoring. The device is widely used in power grid system
