Modification in Elliptic Curve Cryptography based Mutual authentication scheme for smart grid communication using biometric approach

Abstract: Smart grid is a self-sufficient system. That tracks how the energy is used from its source to its final destination. The smart grid can increase the service quality while reducing the consumption of electricity. However, the safety and confidentiality of information data is the major challenge in smart grid environment. To overcome this there are numerous authentication procedures that have been documented. The mutual authentication system for the smart grid that is based on elliptic curve cryptography and biometrics was thus introduced by A.A. Khan et al.s. This protocol is secure from various attacks. But we found an inability of password and biometric updating phase. Therefore we provided the password and biometric updating phase in this protocol.
