Message authentication is the one of the most effective ways to unauthorized and corrupted messages from being forwarded in wireless sensor networks. For this reason so many techniques are available for authentication message in the networks. This paper basically three concepts i.e., secret key generation, message authentication, message encryption and decryption. First one is used for generating secret key for message encryption decryption. After completion of generating secret key, the authors are using digital certification technique for message authentication.
