Wireless sensor networks consist of many inexpensive wireless nodes, each having sensing capability with some computational and communication power. Asymmetric cryptographic algorithms are not suitable for providing security on wireless sensor networks due to limited computation, power, and storage resources available on sensor nodes. Therefore, the energy-efficient security protocol proposed in this paper uses symmetric cryptographic algorithms to support security. To mitigate the drawbacks of symmetric cryptographic algorithms, the session key is changed dynamically, in addition to employing code-hopping technique in non-blocking OVSF codes.
