CAWS - Security Algorithms for Wireless Sensor Networks: A Cellular Automata Based Approach
This addresses security issues for resource-constrained WSNs, but appears incremental as it builds on existing cellular automata approaches.
The paper tackles security challenges in Wireless Sensor Networks (WSNs) by proposing CAWS, a set of cellular automata-based algorithms including CAKD for key management and CASC for secure data communication, which require minimal memory and simple computation.
Security in the Wireless Sensor Networks (WSN) is a very challenging task because of their dissimilarities with the conventional wireless networks. The related works so far have been done have tried to solve the problem keeping in the mind the constraints of WSNs. In this paper we have proposed a set of cellular automata based security algorithms (CAWS) which consists of CAKD, a Cellular Automata (CA) based key management algorithm and CASC, a CA based secure data communication algorithm, which require very small amount of memory as well as simple computation.
