“…Based on Wyner's work, Leung-Yan-Cheong and Hellman studied the Gaussian wiretap channel(GWC) [9], and showed that its secrecy capacity was the difference between the main channel capacity and the overall wiretap channel capacity (the cascade of main channel and wiretap channel). Inspired by the above works, Mitrpant et al [10] studied transmission of confidential messages in the channels with channel state information (CSI). In [10], an inner bound on the capacity-equivocation region was provided for the Gaussian wiretap channel with CSI.…”

In this paper, we investigate the model of wiretap channel with action-dependent channel state information. Given the message to be communicated, the transmitter chooses an action sequence that affects the formation of the channel states, and then generates the channel input sequence based on the state sequence and the message. The main channel and the wiretap channel are two discrete memoryless channels (DMCs), and they are connected with the legitimate receiver and the wiretapper, respectively. Moreover, the transition probability distribution of the main channel depends on the channel state. Measuring wiretapper's uncertainty about the message by equivocation, inner and outer bounds on the capacity-equivocation region are provided both for the case where the channel inputs are allowed to depend non-causally on the state sequence and the case where they are restricted to causal dependence. Furthermore, the secrecy capacities for both cases are bounded, which provide the best transmission rate with perfect secrecy. The result is further explained via a binary example.

“…Note that the coding scheme of [9] is a combination of those in [1,6]. Chen et al [9] generalize Mitrpant et al's work [8] by extending the Gaussian channel to the discrete memoryless channel (DMC), i.e., the result of [8] can be obtained from that of [9]. Recently, N. Merhav [10] studied a variation of the wiretap channel, and obtained the capacity-equivocation region, where both the legitimate receiver and the wiretapper have access to some leaked symbols from the source, but the channels for the wiretapper are more noisy than the legitimate receiver, which shares a secret key with the encoder.…”

“…This channel is also called dirty paper channel. Based on the dirty paper channel, C. Mitrpant et al [8] studied the Gaussian wiretap channel with side information, and provided an inner bound on the capacity-equivocation region. Furthermore, Y. Chen et al [9] investigated the discrete memoryless wiretap channel with noncausal side information, and also provided an inner bound on the capacity-equivocation region.…”

In this paper, the model of wiretap channel has been reconsidered for the case that the main channel is controlled by channel state information (side information), and it is available at the transmitter in a noncausal manner (termed here noncausal side information) or causal manner (termed here causal side information). Inner and outer bounds are derived on the capacity-equivocation regions for the noncausal and causal manners, and the secrecy capacities for both manners are described and bounded, which provide the best transmission rate with perfect secrecy. Moreover, for the case that the side information is available at the transmitter in a memoryless manner (termed here memoryless side information), both the capacity-equivocation region and the secrecy capacity are determined. The results of this paper extend the previous work on wiretap channel with noncausal side information by providing an outer bound on the capacity-equivocation region. In addition, we find that the memoryless side information can not help to obtain the same secrecy capacity as that of the causal case, and this is different from the well known fact that the memoryless manner can achieve the capacity of the channel with causal side information.

“…Physical layer security is recolonized as a promising approach to protect the communications confidentiality against eavesdroppers [8]. The method imposes different challenges in terms of key exchange and distribution, especially in the current trend of dynamic network configurations such as wireless sensor networks and ad-hoc networks.…”

We consider a wireless information surveillance in UAV network, where a legitimate unmanned aerial vehicle (UAV) proactively eavesdrops communication between two suspiciousUAVs. However, challenges arise due to lossy airborne channels and limited power of the UAV. In this paper, we study an emerging legitimate eavesdropping paradigm that the legitimateUAV improves the eavesdropping performance via jamming the suspicious communication. Moreover, a power efficient legitimate eavesdropping scheme, PELE, is proposed to maximize the number of eavesdropped packets from the legitimate UAV while maintaining a target signal to interference plus noise ratio at the suspicious link. Numerical results are shown to validate the performance of PELE. Additionally, four typical fading channel models are applied to the network so as to investigate their impact on PELE.
