This paper deals with Designing cost-efficient, secure network protocols for any Networks is a challenging problem because node in a network itself is resource-limited. Since the communication cost is the most dominant factor in any network, we introduce an energy-efficient Node Energy-Based Encryption and Keying (NEBEK) scheme that significantly reduces the number of transmissions needed for rekeying to avoid stale keys. NEBEK is a secure communication framework where sensed data is encoded using a scheme based on a permutation code generated via the RC4 encryption mechanism. The key to the RC4 encryption mechanism dynamically changes as a function of the residual energy of the node. Thus, a one-time dynamic key is employed for one packet only and different keys are used for the successive packets of the stream. The intermediate nodes along the path to the sink are able to verify the authenticity and integrity of the incoming packets using a predicted value of the key generated by the sender’s virtual energy, thus requiring no need for specific reeking messages. NEBEK is able to efficiently detect and filter false data injected into the network by malicious outsiders. We have evaluated NEBEK’s feasibility and performance analytically and through software simulations. Our results show that NEBEK, without incurring transmission overhead (increasing packet size or sending control messages for rekeying), is able to eliminate malicious data from the network in an energy efficient manner.
