Title: 智能电网高级量测架构可扩展密钥管理协议

Abstract: AMI (Advanced metering infrastructure) plays a critical role in the smart grid. It enables intelligent applications like load control switching, demand side management and meter data management by creating a bidirectional communication network for smart meters and utility systems. Consequently, AMI should be strictly protected to ensure reliable and secure operations of smart grid. In this paper we first show that a recently proposed key management scheme for AMI by Liu et al. suffers from the de-synchronization attack, and at the same time it lacks scalability due to inefficient key management. Then we propose a new scalable key management scheme SKM characterized by combining identity-based cryptosystem and efficient key tree technique. The scheme SKM possesses advantages of efficiency and flexibility in key management. In particular, the cost of SKM is O(log n) in either aspect of computation and communication (n is the number of smart meters), which is significantly reduced from the cost of O(n) in Liu et al.’s scheme. We analyze security and performance of SKM in details to show that SKM is efficient in computation and communication cost.
