This paper focuses on the issues of secure key management for smart grid. With the present key management schemes, it will not yield security for deployment in smart grid. A novel key management scheme is proposed in this paper which merges elliptic curve public key technique and symmetric key technique. Based on the Needham-Schroeder authentication protocol, symmetric key scheme works. Well known threats like replay attack and man-in-the-middle attack can be successfully abolished using Smart Grid. The benefits of the proposed system are fault-tolerance, accessibility, Strong security, scalability and Efficiency.
