TLDR
Simulations in a typical indoor building show that the scheme based on the Neyman-Pearson test is more robust against terminal mobility, and is able to detect spoofing attacks efficiently with small system overhead when the terminal moves with a typical pedestrian speed.Abstract:
We propose an enhanced physical-layer authentication scheme for multi-carrier wireless systems, where transmission bursts consist of multiple frames. More specifically, it is based on the spatial variability characteristic of wireless channels, and able to work with moderate terminal mobility. For the authentication of the first frame in each data burst, the legal transmitter uses the saved channel response from the previous burst as the key for authentication of the first frame in the next burst. The key is obtained either via feedback from the receiver, or using the symmetric channel property of a TDD system. Then the authentication of the following frames in the burst is performed either by a Neyman-Pearson hypothesis test, or a least-squares adaptive channel estimator. Simulations in a typical indoor building show that the scheme based on the Neyman-Pearson test is more robust against terminal mobility, and is able to detect spoofing attacks efficiently with small system overhead when the terminal moves with a typical pedestrian speed.read more

An RSSI-based scheme for sybil attack detection in wireless sensor networks
Murat Demirbas,Youngwhan Song +1 more
TL;DR: This work presents a robust and lightweight solution for sybil attack problem based on received signal strength indicator (RSSI) readings of messages and shows that even though RSSI is time-varying and unreliable in general and radio transmission is non-isotropic, it is feasible to overcome these problems.

Channel Identification: Secret Sharing Using Reciprocity in Ultrawideband Channels
TL;DR: Using the theory of reciprocity for antennas and electromagnetic propagation, a key distribution method is proposed that uses the ultrawideband channel pulse response between two transceivers as a source of common randomness that is not available to enemy observers in other locations.

Detecting identity-based attacks in wireless networks using signalprints
TL;DR: It is shown that a transmitting device can be robustly identified by its signalprint, a tuple of signal strength values reported by access points acting as sensors, allowing detection of a large class of identity-based attacks with high probability.
