Prevention of Cyber Attack in Smart Grid Using Blind Signcryption Scheme

Smart Grid (SG) is a complex system that integrates cyber, physical, and communication or control layers. In the smart grid, the physical layer captures the data and aggregates the data. The aggregated data is transmitted to the cyber layer. The cyber layer makes smart decisions based on aggregated data and sends the control command to the physical layer to manage the energy system effectively and distribute the energy efficiently. The control layer works with the collaboration of the Internet. The Internet layer is susceptible to various cyber-attacks. This manuscript proposes a blind signcryption scheme to decipher the security threat issues. A blind signature is a prevailing technique to hide user information. The proposed method carries out the blind signature procedure on digital documents and uses the concept of the Elliptic Curve Cryptography (ECC) technique. ECC is a lightweight cryptography technique with a reduced key size. The comparative analysis in terms of efficiency and security proves the significance of the proposed technique.
