The design of optimal key management technique which provides higher security with lower complexity and reduced communication overhead and storage requirements is one of the important challenges for the security of the wireless sensor networks. Although many key management protocols are already proposed like Localized Encryption and Authentication Protocol (LEAP), TESLA etc. but these protocols required large key updating overhead and key storing space while the key updating process is also produces the delay because the keys are updated node be node in sequential procedure.
