The wireless sensor nodes utilizes the wireless channels in the frequency bands of the 802.11, 802.16, 802.15.4, 802.15.1 and other similar wireless standards. The wireless sensor networks are built of the small sensor nodes built upon the microcontroller platforms such as PIC, 8051, ARM, AVR, etc. During the periods when the WSN nodes are in working condition, they need secure cryptographic keys for secure propagation of the sensitive information. Efficient key management and distribution scheme play an important role for the data security in WSNs. Existing cryptographic key management and distribution technique usually consume higher amount of energy and put larger computational overheads on Wireless sensor nodes. The cryptographic keys are used on different communication levels of WSN communications i.e. neighbour nodes, cluster heads and base stations. A successful corporate key administration and distribution policy is required to keep up the security of the remote sensor systems. The problems described in the base papers are related to the requirement of energy efficient key exchange policies for WSNs. So to overcome the above problem there is a need to design the model to solve the key-problem of energy efficient and secure key exchange scheme. The proposed model has been found improved after the in-depth result analysis over the given scenario.
