摘要：Smart Grid (SG) is a major electricity trend expected to replace traditional
electricity systems. SG has faster response to electricity malfunctions and improved
utilization of consumed power, and it has two-way communication between providers
and consumers. However, SG is vulnerable to attacks and requires robust
authentication techniques to provide secure authenticity for its components. This
paper analyses previous literature, comprising 27 papers on the status of SG
authentication techniques, main components, and kinds of attacks. This paper also
highlights the main requirements and challenges for developing authentication
approaches for the SG system. This can serve as useful guidance for the development
and deployment of authentication techniques for SG systems and helps practitioners
select authentication approaches applicable to system needs.
