A Secure and Efficient Identity based Proxy Signcryption Scheme for Smart Grid Network
Rachana Patil, Yogesh H. Patil · Journal of Engineering Science and Technology Review · 2022
A smart grid is a modern network system that configures variety of equipment based on Internet of Things and such equipment while working with smart grid systems produces huge amounts of data.As a result the data requires confidentiality and access control.To secure the data access, the proxy signcryption scheme is the most suitable option.In this work we proposed an identity based proxy signcryption scheme for smart grid (IDPSC-SG).The proposed scheme can provide the advantages of both, the proxy signature and proxy signcryption using single algorithm.The comprehensive security study of the proposed scheme shows that, IDPSC-SG can achieve the security requirements of IND-IDPSC-SG-CCA2.Furthermore it also achieve the existential unforgeability against adaptive chosen messages attack (EUF-CMA).The formal verification using AVISPA tool shows that IDPSC-SG is safe under OFMC and CL-Atse.Moreover, extensive performance evaluation indicates its efficiency with respect to computation time.
