Abstract
The transmission of consumer energy consumption reports from smart meters to the power management centers over insecure public communication channels exposes this data to numerous privacy and security attacks. This has seen the development of many authentications and key agreement (AKA) protocols to offer protection to the transmitted data. However, majority of these schemes still face many security, privacy and performance issues. Specifically, anonymity and untraceability features are missing in the majority of the current AKA protocols. In this paper, a privacy-preserving traffic signaling protocol is developed. Its security analysis shows that it is robust against impersonation, Man-in-the-Middle (MitM), de-synchronization and replay attacks. In addition, it provides untraceability, anonymity and perfect forward key secrecy. Moreover, it has average computation and storage costs, and the lowest communication costs among other related protocols.
