Nodes in a sensor network may be lost due to malicious attack or either power loss. To extend the life time of the sensor network the novel Authentication Protocol is needed to overcome the internal attacks. In a defense scenario the advisory or intruder may directly deploy the malicious node or manipulate existing node to introduce malicious new node to the network. This paper focus on Novel Authentication Protocol to provide a security solution against known malicious attacks. It provides better authentication protocol for access control in the sensor network. The authors also emphasis on the confidentiality for the information access in between the sensor networks.
