Power system information security encryption system based on power distribution terminal

Abstract

The invention discloses a power system information security encryption system based on a power distribution terminal. The encryption system comprises a master station end and an integrated terminal, asecurity encryption device is arranged between the master station end and the integrated terminal, and the master station end, the integrated terminal and the security encryption device communicate with one another through transmission channels; the security encryption device can analyze and verify a ciphertext issued by the master station end, determinies whether to transmit original data to theintegrated terminal or not according to a verification result, and also can encrypt data uploaded by the integrated terminal, and the data is transmitted to the main station end in a ciphertext form,so that the communication data security between the integrated terminal and the main station can be realized, and the standard communication protocol and information security protection requirementsof a distribution automation system are met.

Description

technical field [0001] The invention relates to the technical field of security encryption, in particular to a power system information security encryption system based on a power distribution terminal. Background technique [0002] With the widespread application of information and communication technologies such as big data, cloud computing, Internet of Things, mobile Internet, and broadband wireless, the probability of smart grids being attacked by viruses, Trojan horses, system vulnerabilities, and denial of service has also increased, which also brings traditional The power information security protection system based on physical protection has brought challenges. In particular, the large-scale network paralysis incident in the United States has put forward higher requirements for the security protection of key information infrastructure. [0003] With the continuous advancement of distributed energy, electric vehicles connected to the grid, and communication technolog...

Problems solved by technology

[0005] The solution of some foreign companies is that community users first use a security protocol to send their own power usage information to the community gateway, and then the community gateway summarizes the power usage information of all users and sends it to the power company (during this process, the community gateway cannot obtain the information of each user) specific power usage information)
