Hybrid Key Management Scheme for Secure AMI Communications

AbstractAdvanced Metering Infrastructure (AMI) is an essential attribute of Smart Grid. To ensure secure communication for smart metering one must ensure that the data which is sent or received is authorized and confidential. This article deals with a hybrid encryption scheme for unicast, multicast and broadcast communication in AMI. To ensure confidentiality, integrity and authenticity, a Key Management Scheme (KMS) for hybrid communication modes is proposed. The proposed scheme provides excellent level of security and reduces the computational load on Smart Meter (SM)
