Power distribution network information secure transmission method based on quantum encryption

Abstract

The invention discloses a power distribution network information secure transmission method based on quantum encryption. The method comprises the following steps: S1, establishing communication; s2, the edge server obtains the request information of the power distribution and utilization terminal, and generates a binary random number sequence L1 according to the occupation condition of the request information in the first-level information block A; s3, the master station server generates response information blocks according to the request information, and generates a binary random number sequence L2 according to the occupation condition of the first-level response information blocks; s4, the quantum encryption server generates a key pool Q, and configures a public key pool Puk and a private key pool Pri for the quantum key pool Q; s5, respectively collecting quantum keys by taking the binary random number sequences L1 and L2 as random numbers; s6, the edge server carries out encryption by using the obtained quantum secret key, and carries out decryption by using the obtained quantum secret key; and S7, the power distribution and utilization terminal obtains corresponding response information. According to the scheme, positioning encryption and decryption of parallel data are realized, and the encryption and decryption efficiency based on the quantum key is improved.

Description

technical field [0001] The invention relates to the technical field of distribution network information security, in particular to a method for secure transmission of distribution network information based on quantum encryption. Background technique [0002] In order to improve the information security protection level of business master stations, channels and terminal links, the State Grid Corporation of China issued the "Technical Specifications for Security Protection of Electricity User Electricity Information Collection System" (Q / GDW 377-2009), "Network Security of Distribution Automation System Protection Scheme" and other standards or guidance documents to ensure the safe and stable operation of the distribution network. However, the current security protection measures are more focused on the master station system with centralized deployment of software and hardware, while the security protection measures for business terminals and communication terminals with multi...
