A Lightweight Watermark Scheme Utilizing MAC Layer Behaviors for Wireless Sensor Networks

Security is a major concern in wireless sensor network designing which suffers from many stringent hardware and software restrictions. It has attracted a large amount of attention from the research circle as security requirements became more and more indispensable in the Internet of Thing (IoT) evolution. An effective security mechanism is essential for deploying sensor networks. This paper proposes a security technique based on MAC behaviors for lightweight digital watermarking which aims to attain confidentiality and authentication for data. Embedded watermark values are constructed by information from MAC layer parameters which are simple to implement and resistant to attack. The numerical results and security analysis show proficiency of the proposed watermark scheme and evaluate the tradeoff between watermark detection probability and energy consumption of the network model.
