Physical-layer authentication can address physical layer vulnerabilities and security threats in wireless sensor networks, and has been considered as an effective complementary enhancement to existing upper-layer authentication mechanisms.In this paper, to advance the existing research and improve the authentication performance, we propose a novel physical layer assisted authentication scheme for mobile wireless sensor networks.In our proposed scheme, we explore the reciprocity and spatial uncorrelation of the wireless channel to verify the identities of involved gtech brush bar transmitting users and decide whether all data frames are from the same sender.In our wella color charm 050 cooling violet proposed scheme, a new method is developed for the legitimate users to compare their received signal strength (RSS) records, which avoids the information from being disclosed to the adversary.

Our proposed scheme can detect the spoofing attack even in a high dynamic environment.We evaluate our scheme through experiments under indoor and outdoor environments.Experiment results show that our proposed scheme is more efficient and achieves a higher detection rate as well as keeping a lower false alarm rate.
