This paper investigates data transmission and physical layer secrecy in cognitive radio network. We propose to apply full duplex transmission and dual antenna selection at secondary destination node. With the full duplex transmission, the secondary destination node can simultaneously apply the receiving and jamming antenna selection to improve the secondary data transmission and primary secrecy performance respectively. This describes an attractive scheme in practice: unlike that in most existing approaches, the secrecy performance improvement in the CR network is no longer at the price of the data transmission loss. The outage probabilities for both the data transmission and physical layer secrecy are analyzed. Numerical simulations are also included to verify the performance of the proposed scheme.

“…Many previous works have been devoted to the study of PLS over fading wiretap channels (see, for example, [15][16][17][18] and references therein). However, they are mostly focused on asymptotic secrecy targets and consider ideal conditions (like capacity achieving codes and continuous modulations).…”

Abstract:We propose and assess an on-off protocol for communication over wireless wiretap channels with security at the physical layer. By taking advantage of suitable cryptographic primitives, the protocol we propose allows two legitimate parties to exchange confidential messages with some chosen level of semantic security against passive eavesdroppers, and without needing either pre-shared secret keys or public keys. The proposed method leverages the noisy and fading nature of the channel and exploits coding and all-or-nothing transforms to achieve the desired level of semantic security. We show that the use of fake packets in place of skipped transmissions during low channel quality periods yields significant advantages in terms of time needed to complete transmission of a secret message. Numerical examples are provided considering coding and modulation schemes included in the WiMax standard, thus showing that the proposed approach is feasible even with existing practical devices.

“…Thus, in the application of PLS, consideration of OFDM systems is an important element. This problem was addressed by Renna et al [29], [30] by considering the physical layer of an OFDM transmitter/receiver pair in the presence of an eavesdropper that might either use an OFDM structure or choose a more complex receiver architecture. The analysis was made possible by modeling the system as a particular instance of a high dimensional MIMO wiretap channel.…”

Physical layer security (PLS) draws on information theory to characterize the fundamental ability of the wireless physical layer to ensure data confidentiality. In the PLS framework it has been established that it is possible to simultaneously achieve reliability in transmitting messages to an intended destination and perfect secrecy of those messages with respect to an eavesdropper by using appropriate encoding schemes that exploit the noise and fading effects of wireless communication channels. Today, after more than fifteen years of research in the area, PLS has the potential to provide novel security solutions that can be integrated into future generations of mobile communication systems. This chapter presents a tutorial on advances in this area. The treatment begins with a review of the fundamental PLS concepts and their corresponding historical background. Subsequently it reviews some of the most significant advances in coding theory and system design that offer a concrete platform for the realization of the promise of this approach in data confidentiality.
