Metering operation and maintenance system data security transmission method and system

Abstract

The invention discloses a metering operation and maintenance system data security transmission method and system, wherein the method comprises the steps that: an application end transmits a request toan operation and maintenance platform, the operation and maintenance platform calls a detection cipher machine, the detection cipher machine generates a public key and a private key and transmits thepublic key and the private key to the operation and maintenance platform and the cipher machine, and then the operation and maintenance platform transmits the public key to the application end; and the application end encrypts to-be-transmitted data into a ciphertext and sends the ciphertext to the operation and maintenance platform, the operation and maintenance platform sends the ciphertext tothe cipher machine, the cipher machine decrypts the ciphertext to obtain a plaintext, finally, the cipher machine sends the plaintext and the ciphertext to the detection cipher machine, the detectioncipher machine decrypts the ciphertext again and verifies the plaintext, and if decryption is correct, the cipher machine sends the plaintext to the operation and maintenance platform, and the operation and maintenance platform operates. According to the method and the system, the problem of low security of data transmission caused by the fact that a MD5 algorithm cannot prevent collision during data transmission and original transmission data is tampered but not found out is solved, and the security and reliability of data transmission are ensured.

Description

technical field [0001] The present application relates to the field of power systems, and in particular to a method and system for secure data transmission of metering operation and maintenance systems. Background technique [0002] In the power system, the metering operation and maintenance system is often used to realize the operation and maintenance of the metering device, including the maintenance and repair of the metering device. The metering device is used to measure and record the amount of power generation, power supply, plant power consumption, and line loss power. and measuring instruments for user electricity consumption. In the actual operation and maintenance activities, the staff first checks the operation status of the metering device, generates on-site operation and maintenance data, and then enters the on-site operation and maintenance data into the label on the metering device. Finally, the staff can pass the application terminal Scan the label to obtain ...
