Wireless sensor network technology is a fast growing priority area of research. It is expected that wireless sensor technology shall make inroads into many public utilities namely, disaster management, transport, process control, security, environment and wild life monitoring, etc. The wireless sensor networks differ from other networks in two primary aspects. The first is that unlike other networks the Wireless sensor networks have a dedicated function to perform and not any sort of information exchange. The other aspect of the network is that the nodes may or may not be accessible after deployment. This paper describes an encryption technique, specifically suitable for wireless sensor networks. The scheme works on a public key with dynamic encryption changes.
