A key management scheme for secure communications of advanced metering infrastructure

Abstract

Key management for secure communications of Advanced Metering Infrastructure is an unsolved problem until now. The difficulties and their basic solutions for AMI to choose a key management scheme will be summed up after the studies of AMI system structure, business process and cyber security requirements, proposing a key management scheme based on a hybrid-tree graph for AMI. The cyber security, including key security, key freshness, forward & backward security, etc., can be satisfied by the presented scheme, while the overhead of the scheme is reasonable. Based on the analysis, the presented scheme is a possible solution for AMI. © 2011 Springer-Verlag.
