A two-way authentication method for a shared electricity interactive system

Abstract

The present invention proposes a two-way authentication method for a shared electricity interactive system, including: client registration: the server and the client use the first digital certificate to realize remote authentication and identity registration; local authentication: when the client program receives the user's After the login request, compare the user information; smart power supply device authentication: the server compares the decrypted test data with the random number and timestamp sent before, and returns the successful authentication information of the smart power supply device to the user if they are consistent, otherwise Return the alarm signal; content descrambling: the client establishes a connection with the smart power supply device, and uses the preset encryption algorithm to encrypt and transmit the data; add a signature: the client adds a Hash signature to the data sent to the smart power supply device, and the Hash The signature and data are transmitted together to realize data encryption. The invention improves the use safety of the intelligent power supply equipment, and realizes the safe interaction between the electric equipment and the intelligent power supply equipment.

Description

technical field [0001] The invention relates to the technical field of electronic power, in particular to a two-way authentication method for an interactive system for sharing electricity. Background technique [0002] At present, the operating environment of the power system is becoming more and more complex, and the attack methods and intensity of the network communication of the power system are showing an upward trend. The smart power consumption system involves issues such as the key core data of the power grid company and the security and privacy of large-scale users. Once the data is maliciously attacked during channel link transmission and causes information leakage, illegal use, and tampering, it may pose a threat to national security and Societal and economic losses are irreparable. [0003] In addition to physical security protection for data communication between users and intelligent interactive electricity vending terminals in the process of shared and interac...

AI Technical Summary

Problems solved by technology

Reliable authentication between the user's smart electricity vending terminals is the first line of defense. The main solutions are: 1) Users cannot identify whether the port connected to their own electrical equipment is safe. If it is a fake port, the user's purpose is often not achieved

2) If the port is forged or hacked, the user's personal information stored in the electrical device will be at great risk
