Wireless Sensor Network (WSN) is an important component of the Internet of Things architecture. It operates in hostile environment sectors to provide a lot of interesting applications. However, WSN is constrained by limited resources such as power or computational cost, making it vulnerable to many kinds of attacks. Hence, finding an appropriate security solution to protect node authentication and sensor data integrity which are two of the most critical security issues has always attracted researchers. In which, the digital watermarking technique can be used to secure sensory data while keeping a reasonable computation cost. However, nowadays, node clone attacks can create a war of inside attacks which damages heavily to the performance of sensor networks. Hence, the confidentiality and integrity of sensor network entities are raised more challenges related to complexity and practical problems. This paper proposes a novel lightweight mixed secure scheme based on watermarking techniques to protect sensory data and defend against node clone attacks. Numerical results and security analysis will be provided in the paper to validate the advantage of the proposed security protocol.
