Efficient communication with maintenance of stability between sensor nodes is one of the most important factors in WSN. Recent studies suggest various group key management protocols for maintaining stability between sensors in spite of somewhat lower efficiency of protocol operating in WSN. This paper proposes efficient hybrid key establishment protocol for sensor network self-organized with equal distribution between sensor nodes. The proposed protocol is applicable to distributed environment with expansional aspect without control of base station, combining with elliptic curve Diffie-Hellman key establishment with implicated certificate and symmetric key encryption technology. For performance evaluation of the proposed protocol, this study dividedly evaluated storage cost, communication complexity and computation complexity and showed computation cost 1.3% lower than that of Kotzanikolaou technique.
