Abstract
The electricity industry has been developed through the introduction of the smart grid. This has brought about two-way communication to the grid and its components. The smart grid has managed to increase the efficiency and reliability of the traditional power grid over the years. A smart grid has a system that is used to measure and collect readings for power consumption reflection, and the system is known as the Advanced Metering Infrastructure. The advanced metering infrastructure has its components too which are the smart metre, metre control system, collector or concentrator and communication networks (wide area network, neighbourhood area network, and home area network). The communication networks in the advanced metering infrastructure have created a vulnerability to cyber-attacks over the years. The reliability of the power grid to consumers relies on the readings from the smart metre, and this brings about the need to secure the smart metre data. This article presents a review of key management methods in advanced metering infrastructure environments. The article begins with an overview of advanced metering infrastructure and then shows the relationship between the advanced metering infrastructure and the smart grid. The review then provides the security issues related to advanced metering infrastructure. Finally, the article provides existing works of key management methods in advanced metering infrastructure and future directions in securing advanced metering infrastructure and the smart grid.
Highlights
Every country’s economic and social welfare relies mostly on electricity
The work of Kumar et al.[57] proposed a key management scheme designed for home area network (HAN) having low rekeying overheads and robustness that is enhanced, allowing the smart metres and HAN to share a session key among themselves
The work focuses on studying the key management methods used in AMI
Summary
Every country’s economic and social welfare relies mostly on electricity. Electricity is responsible for daily operations in industries and is used for domestic purposes. This transmission mode is used for communications between two points.[31] The data are transmitted from the sender and go directly to one specified receiver These two devices participate in the communication and other devices in the network stay idle.[32] In the AMI network, unicast transmission or communication occurs when the smart metre sends consumption data to the utility provider.[33]. This transmission mode is used for communication between one point and many specified points, referred to as a group.[34] Multicast transmission can be a group of senders to a group of receivers when many senders communicate to many receivers simultaneously,[35] group to group.
