Encrypt message with strongly secure key which is known only by sending and recipient end is a significant aspect to acquire robust security in sensor network. The secure exchange of key between sender and receiver is too much difficult task in resource constraint sensor network. To achieve secure key agreement is challenging task for sensor network environment. The key management helps to maintain confidentiality of secret information from unauthorized users. It can also check the integrity of the exchanged message to verify the authenticity.
