Abstract: Message authentication is used to prevent the unauthorized messages forwarded in the Wireless Sensor Networks (WNS). The main aim of this project is to prevent unauthorized and corrupted message by allowing intermediate efficient node authentication. Many authentication schemes have been proposed to provide message authenticity; these schemes can be either public-key based approaches or symmetric-key based approaches. Scalable authentication scheme based on Elliptic Curve Cryptography (ECC) enables the intermediate node to authenticate the message and provide Hop by Hop message authentication. Route request is encrypted for authentication of messages with source privacy. An efficient key management framework is proposed to ensure isolation of the compromised node. The compromised node will be identified and alert information sends to all nodes.
Keywords: Wireless Sensor networks, Message authentication, Source privacy, Symmetric key cryptosystem, compromised node.
