Lightweight security protocol for Wireless Sensor Networks
Kamanashis Biswas · 2014
Wireless Sensor Network (WSN) consists of a large number of small sensor nodes (SNs) that are usually deployed in hostile environments. These nodes are vulnerable to a number of security attacks and it is difficult to implement complex cryptographic schemes in SNs due to their resource constrained nature. Hence, WSNs need energy efficient and secure communication schemes in terms of storage space, power consumption and operation speed. In this work, we propose a secure and lightweight encryption scheme based on chaotic map and genetic operations. We also present some initial results of security strength and performance evaluation experiments.
