Abstract:
Electrical smart grid is rapidly growing worldwide. Advances in smart metering infrastructure have led to the creation of networks for bidirectional communication between neighborhood electric smart meters and utility management services. Current security solutions for such networks are proprietary, ad-hoc, and often built with a limited understanding of new security threats and risks faced by modern metering infrastructure. Recent research showed existing vulnerabilities in Advanced Metering Infrastructure (AMI) apparatuses, and motivated the need for a new publicly open suite of protocols that would be tailored for security needs of modern AMI systems. We propose a suite of secure protocols for communication between smart meters and smart grid infrastructure. Along with enforcing message integrity and secrecy through typical means, our protocols provide non-repudiation and traitor tracing guarantees. Proposed protocols help to mitigate several types of attacks on smart grid by identifying the origin of attacks against AMI. We implement and evaluate security, scalability, and performance of the proposed protocols. The protocols can support up to thirty thousand smart meters per data collector with an average delay of 22ms per data deposit transaction. We estimate scalability and limitation of the protocols on different processor architectures including Intel i386, ARMv5, and Atom N290.
