Secure and Efficient 4-way Handshake in Smart Grid to DoS Attacks Mitigation

Distributed communication networks provide proper connection with ooptimum cost between different domains of smart gride such as: home area network, neighbor area network and substation area network. With respect to handshake and key distribution are security challenges in smart grid, this paper proposed novel distribution and dynamic key procedures to enhance network resilience against malicious DoS attack. Proposed procedures using two famous security protocols: SAE and EMSA. These procedures are based on hash function and protocol stage dependency to improve network resilience against DoS attacks, because SAE and EMSA use 4-way handshake. Proposed procedures have optimum overhead. Finally, AVISPA is applied to prove the security of the enhanced protocol in smart grid. With extremely simulations and extended DoS attack model securities of proposed procedures are proved.
