Sensor network-based AMI network security

AMI is the totality of systems and networks used to measure, collect, store, analyze, and use energy usage data. The industry and technology surrounding AMI has been evolving at a very fast pace for the past several years. In this paper, we propose new key establishment and security algorithm based on public key cryptography to solve AMI network security problems. We evaluate the performance of the proposed key establishment procedure compared with existing algorithm, and we find that the performance of proposed algorithm.
