Abstract
The smart metering infrastructure of the smart grid needs an efficient security mechanism since the smart meters have limited computational power and storage. Considering the limitation, this paper presents a lightweight au-thentication and key establishment scheme to use between the Neighbourhood Area Network (NAN) gateway and domestic smart meter. The scheme includes one-time registration of smart meter with NAN gateway and multiple times mutual authentication between the NAN gateway and smart meter. The proposed protocol ensured security with minimum computation and storage to enable limited power smart meter to authenticate itself with NAN. The security robustness of the proposed model was analysed and proved using the Automated Validation of Internet Security Protocols and Applications (AVISPA) tool. Also, the performance evaluation shows the effectiveness of the proposed scheme with the property of efficiency and lightweight than the existing schemes with respect to the computational cost.
