“…Consistent results are observed with 16-QAM in our extensive simulations. Figure 2 compares the proposed scheme with the method in [12] in terms of the detection error probability with QPSK modulation and T = 10. The detection threshold is determined based on the MAP criterion in (5).…”

“…Perfect CSI is an ideal assumption typically unavailable in practical systems, especially in fast-fading systems, multi-hop systems, and cooperative systems with misbehaving relays (which could compromise channel estimation), in which cases noncoherent schemes without the need of instantaneous CSI are preferable, L.-C. Lo as considered in [10], [11]. In the context of relay misbehavior detection, noncoherent tracing-based detection was proposed for single-relay [12] and two-relay space-time coded systems [13]. The method in [12] is based on counting the numbers of received tracing symbols whose phases are located within the same quadrant and is suitable for the garbling misbehaving pattern with QPSK.…”

This letter considers a three-node cooperative network with an untrusted relay. We propose a noncoherent relay misbehavior detection scheme for decode-and-forward (DF) systems based on the correlation among channel estimates at the destination under quasistatic channels. The proposed scheme does not require instantaneous channel state information and can detect arbitrary misbehavior patterns and various signal constellations. An asymptotic analysis of the proposed correlationbased detection statistic is conducted to facilitate characterizing the detection performance given a specific misbehaving pattern and customizing the detector to meet a specified system requirement. Simulation results validate the analysis and demonstrate improved performance of the proposed scheme in various relay misbehaving scenarios.Index Terms-Cooperative networks, decode-and-forward, relay misbehavior detection, noncoherent communication.1089-7798 (c)

“…On the other hand, the in-transit messages may also be garbled [10,13]. To unmask the hypocritical relays, some specific tracing symbols can be added to the informative messages [10,13]; otherwise, the malicious detection can also be conducted blindly, based on the characteristics of hybrid automatic repeat request [11], the credit-based incentive transmission scheme [12], or the received signal's correlation [14].…”

In the relay networks, two typical issues of physical layer security are selfishness and garbling. As a matter of fact, a certain nontypical but severely harmful misbehavior can also remove the cooperative diversity gain. Here, we coin the masquerading attack to indicate this kind of misbehavior. A masquerade relay can always pretend to be the best one to forward signals and, in consequence, deprive the others of the opportunities to cooperate. To the best of our knowledge, the impact of the masquerading attack has not yet been fully investigated. In this paper, multiple masquerade relays with random masquerading behavior are taken into account. Also, the complete channel effects, including the effects of the flat Rayleigh fading, log-normal shadowing, and path loss, are considered such that the geographical effects of the network topology can be completely captured. At last, the impact of the masquerade relays are evaluated in terms of the outage probability and end-to-end capacity.

We propose a physical-layer technique for checking the integrity of information provided by an intermediate node (relay) in cooperative relay communication systems. The proposed approach, built on the theory of likelihood ratio test, exploits the physical-layer signal from the source in detecting any data modification (false data injection attack) made by the relay. We present the optimum detection method that minimizes the end-to-end outage probability and the minmax detection method that minimizes the maximum possible outage probability under unknown attack probability. We show that the optimum detection technique can provide almost the same end-to-end outage probability that can be provided by the ideal cryptographic technique that perfectly detects the false injection at the expense of high computational cost and bandwidth overhead. The proposed physical integrity check can be used as an additional layer of protection or can complement to the conventional cryptographic techniques.Index Terms -Physical integrity check, false data injection attack, likelihood ratio test, optimum detection, minmax detection, cooperative relay communications.
