An efficient authenticated key agreement scheme supporting privacy-preservation for smart grid communication

As a branch of the next generation grid, smart grid(SG) combines information and communication technology with traditional grid architecture, which can greatly improve the efficiency and reliability of traditional power systems. However, the tampering of power data in smart grid communications may lead to unclear decisions related to power demand management. So, a secure authentication method which achieves SG device validation in different regions is a basic requirement. In the paper, we put forth a secure authentication key agreement (AKA) scheme supporting privacy-preservation in SG communications. This scheme allows SG devices and service provider(SP) to establish secret session key through mutual authentication. With the session key, the sensitive information can be exchanged securely. Through rigorous security and performance analysis, our proposed solution has stronger security functions and higher computational efficiency than related solutions in the smart grid.

Automated summary

Smart grid integrates information and communication technology with traditional grid architecture to enhance efficiency and reliability of power systems. A secure authentication method is essential to prevent data tampering in smart grid communications. The proposed AKA scheme in this paper supports privacy preservation and enables secure communication between SG devices and service providers.
