Classical Number Theory based Vs Chaos based Cryptography for Wireless Sensor Networks: A Research Perspective

Wireless Sensor Networks (WSN) have fascinated the whole world with their capability to connect to the inhabitable regions. Their applicability to almost every possible area makes it more interesting. Needless to say, that there are certain shortcomings of these tiny devices (sensors) in terms of their memory, processing and battery and hence classical network practices are inapplicable to these networks. Security is a major concern in WSN as they are deployed in hostile regions. Classical security techniques based on number theory are not suitable to energy constrained WSN. This paper aims to discuss the advantages and drawback of introducing the chaotic and fractal based security schemes to WSN. Application of security techniques based on Chaos and Fractals is first of its kind in the field of WSN and expected to revolutionize the field of Sensor Networks.
