PHY-Layer Authentication Using Duobinary Signaling for Spectrum Enforcement
IEEE Transactions on Information Forensics and Security, 2016Co-Authors: Vireshwar Kumar, Jung-min Jerry Park, Kaigui BianAbstract:Spectrum security and enforcement is one of the major challenges that need to be addressed before spectrum sharing technologies can be adopted widely. The problem of rogue transmitters is a major threat to the viability of spectrum sharing. One approach for deterring rogue transmissions is to enable receivers to authenticate or uniquely identify transmitters. Although cryptographic mechanisms at the higher layers have been widely used to authenticate transmitters, the ability to authenticate transmitters at the physical (PHY) layer has a number of key advantages over higher layer approaches. In existing schemes, the authentication Signal is added to the Message Signal in such a way that the authentication Signal appears as noise to the Message Signal and vice versa. Hence, existing schemes are constrained by a fundamental tradeoff between the Message Signal’s Signal-to-noise ratio (SNR) and the authentication Signal’s SNR. In this paper, we extend the precoded duobinary Signaling (P-DS) technique to devise a new PHY-layer authentication scheme called P-DS for authentication (P-DSA). P-DSA exploits the redundancy introduced by P-DS to embed the authentication Signal into the Message Signal. P-DSA is not constrained by the aforementioned tradeoff between the Message and authentication Signals. Our results show that P-DSA improves the detection performance compared with the prior art without sacrificing Message throughput or increasing transmission power.

PHY-layer authentication using hierarchical modulation and duobinary Signaling
2014 International Conference on Computing Networking and Communications (ICNC), 2014Co-Authors: Vireshwar Kumar, Jung-min Park, Charles T. Clancy, Kaigui BianAbstract:In a cognitive radio network, the non-conforming behavior of rogue transmitters is a major threat to opportunistic spectrum access. One approach for facilitating spectrum enforcement and security is to require every transmitter to embed a uniquely-identifiable authentication Signal in its waveform at the PHY-layer. In existing PHY-layer authentication schemes, known as blind Signal superposition, the authentication/identification Signal is added to the Message Signal as noise, which leads to a tradeoff between the Message Signal's Signal-to-noise (SNR) and the authentication Signal's SNR under the assumption of constant average transmitted power. This implies that one cannot improve the former without scarifying the latter, and vice versa. In this paper, we propose a novel PHY-layer authentication scheme called hierarchically modulated duobinary Signaling for authentication (HM-DSA). HM-DSA introduces some controlled amount of inter-symbol interference (ISI) into the Message Signal. The redundancy induced by the addition of the controlled ISI is utilized to embed the authentication Signal. Our scheme, HM-DSA, relaxes the constraint on the aforementioned tradeoff and improves the error performance of the Message Signal as compared to the prior art.

PHY-layer authentication by introducing controlled inter symbol interference
2013 IEEE Conference on Communications and Network Security (CNS), 2013Co-Authors: Vireshwar Kumar, Charles T. Clancy, Jung-min Jerry” Park, Kaigui BianAbstract:Spectrum security and enforcement is one of the major challenges that need to be addressed before spectrum-agile and opportunistic spectrum access technologies can be deployed. Rogue transmitters are a major threat to opportunistic spectrum access. One approach for deterring rogue transmissions is to enable receivers to authenticate or uniquely identify secondary transmitters. Although cryptographic mechanisms at the higher layers have been widely used to authenticate transmitters, the ability to authenticate transmitters at the physical (PHY) layer has a number of key advantages over higher-layer approaches. In existing schemes, the authentication Signal is added to the Message Signal in such a way that the authentication Signal appears as noise to the Message Signal and vice versa. Hence, existing schemes are constrained by a fundamental tradeoff between the Message Signal's Signal-to-noise ratio (SNR) and the authentication Signal's SNR. In this paper, we propose a novel PHY-layer authentication scheme called Precoded Duobinary Signaling for Authentication (P-DSA). P-DSA introduces some controlled amount of inter-symbol interference (ISI) into the data stream. The addition of the controlled ISI introduces redundancy in the Message Signal which can be utilized to embed the authentication Signal. In this way, P-DSA relaxes the constraint on the aforementioned tradeoff. Our results show that P-DSA achieves superior detection performance compared to the prior art without sacrificing Message throughput or increasing power.

secure degrees of freedom of one hop wireless networks
IEEE Transactions on Information Theory, 2014Co-Authors: Sennur UlukusAbstract:We study the secure degrees of freedom (d.o.f.) of one-hop wireless networks by considering four fundamental wireless network structures: 1) Gaussian wiretap channel; 2) Gaussian broadcast channel with confidential Messages; 3) Gaussian interference channel with confidential Messages; and 4) Gaussian multiple access wiretap channel. The secrecy capacity of the canonical Gaussian wiretap channel does not scale with the transmit power, and hence, the secure d.o.f. of the Gaussian wiretap channel with no helpers is zero. It has been known that a strictly positive secure d.o.f. can be obtained in the Gaussian wiretap channel by using a helper, which sends structured cooperative Signals. We show that the exact secure d.o.f. of the Gaussian wiretap channel with a helper is ${{1}\over{2}}$ . Our achievable scheme is based on real interference alignment and cooperative jamming, which renders the Message Signal and the cooperative jamming Signal separable at the legitimate receiver, but aligns them perfectly at the eavesdropper preventing any reliable decoding of the Message Signal. Our converse is based on two key lemmas. The first lemma quantifies the secrecy penalty by showing that the net effect of an eavesdropper on the system is that it eliminates one of the independent channel inputs. The second lemma quantifies the role of a helper by developing a direct relationship between the cooperative jamming Signal of a helper and the Message rate. We extend this result to the case of $M$ helpers, and show that the exact secure d.o.f. in this case is ${{M}\over{M+1}}$ . We then generalize this approach to more general network structures with multiple Messages. We show that the sum secure d.o.f. of the Gaussian broadcast channel with confidential Messages and $M$ helpers is 1, the sum secure d.o.f. of the two-user interference channel with confidential Messages is ${{2}\over{3}}$ , the sum secure d.o.f. of the two-user interference channel with confidential Messages and $M$ helpers is 1, and the sum secure d.o.f. of the $K$ -user multiple access wiretap channel is ${{K(K-1)}\over{K(K-1)+1}}$ .

secure degrees of freedom of the gaussian wiretap channel with helpers
Allerton Conference on Communication Control and Computing, 2012Co-Authors: Sennur UlukusAbstract:The secrecy capacity of the canonical Gaussian wiretap channel does not scale with the transmit power, and hence, the secure d.o.f. of the Gaussian wiretap channel with no helpers is zero. It has been known that a strictly positive secure d.o.f. can be obtained in the Gaussian wiretap channel by using a helper which sends structured cooperative Signals. We show that the exact secure d.o.f. of the Gaussian wiretap channel with a helper is ½. Our achievable scheme is based on real interference alignment and cooperative jamming, which renders the Message Signal and the cooperative jamming Signal separable at the legitimate receiver, but aligns them perfectly at the eavesdropper preventing any reliable decoding of the Message Signal. Our converse is based on two key lemmas. The first lemma quantifies the secrecy penalty by showing that the net effect of an eavesdropper on the system is that it eliminates one of the independent channel inputs. The second lemma quantifies the role of a helper by developing a direct relationship between the cooperative jamming Signal of a helper and the Message rate. We extend this result to the case of M helpers, and show that the exact secure d.o.f. in this case is M/M+1.

Lightweight Tag-Based PHY-Layer Authentication for IoT Devices in Smart Cities
IEEE Internet of Things Journal, 2020Co-Authors: Pinchang Zhang, Hewu Li, Yulong Shen, Xiaohong JiangAbstract:This article proposes a general and lightweight PHY-layer authentication framework for the Internet of Things (IoT) devices in smart cities, based on tag embedding and tag verification. More specifically, a tag Signal carefully designed to be independent of the Message Signal of a transmitter [i.e., an IoT device (IoTD)] is encrypted and embedded into the Signal of the device, and the tag Signal is then retrieved at a receiver based on Signal detection techniques to verify if it is from the legitimate IoTD or from an illegitimate adversary. With the help of matrix analysis and composite hypothesis testing theories, analytical models are further developed to depict the authentication performance of the proposed authentication framework under various tag Signal models. We then provide numerical results to validate these analytical models and to illustrate how authentication performance against the typical impersonation attack varies with system parameters. Finally, we include discussions to demonstrate the effectiveness of the proposed authentication solution in resisting against other various attacks like replay, unauthorized detection, tampering, and man-in-the-middle.
