A node clone attack detection scheme based on digital watermark in WSNs
Tonghui Guan, Yonghong Chen · 2016
Wireless sensor networks are composed of many low-cost sensors deployed in harsh environments generally, which result in sensors suffer from physical attacks in which an adversary can compromise the node and carry out clone attacks. In this paper, we propose a reversible watermarking scheme which is based on data sampling interval against node clone attack. The watermark are computed from one data sampling time and embedded into the group data. The cluster completely reconstructs the watermark and statistical judge extracted watermark characteristics. Performance analysis and simulation also shows that the scheme has an effective detection results.
