“…In other words, the bigger d min is expected to yield a higher mutual information. Therefore, we aim to select a TAS pattern of maximizing the minimum Euclidean distance over desired channel or minimizing the minimum Euclidean distance over eavesdropping channel [12], which are formulated as follows Here, we obtain two TAS patterns by (24) and (25), then we select the one which results in higher R s . Note that some low complexity methods for efficiently solving the problems in (24) and (25) can be found in [15], [16], [18].…”

In this paper, a secure spatial modulation (SM) system with artificial noise (AN)-aided is investigated. To achieve higher secrecy rate (SR) in such a system, two high-performance schemes of transmit antenna selection (TAS), leakage-based and maximum secrecy rate (Max-SR), are proposed and a generalized Euclidean distance-optimized antenna selection (EDAS) method is designed. From simulation results and analysis, the four TAS schemes have an decreasing order: Max-SR, leakage-based, generalized EDAS, and random (conventional), in terms of SR performance. However, the proposed Max-SR method requires the exhaustive search to achieve the optimal SR performance, thus its complexity is extremely high as the number of antennas tends to medium and large scale. The proposed leakage-based method approaches the Max-SR method with much lower complexity. Thus, it achieves a good balance between complexity and SR performance. In terms of bit error rate (BER), their performances are in an increasing order: random, leakage-based, Max-SR, and generalized EDAS.

“…4 demonstrates the asymptotic secrecy rates for the proposed SSK transmission scheme with the CSI-based antenna index assignment. It is assumed that the perfect reciprocity holds, and hence, the achievable secrecy rates for high SNRs are evaluated using (10). It can be inferred from the figure that increasing the number of transmit antennas yields considerable gains in terms of the secrecy rates.…”

We propose a secure transmission scheme based on space shift keying (SSK) in which the indices associated with the transmit antennas are assigned dynamically according to the channel towards the legitimate receiver. We first derive an asymptotic secrecy rate under the perfect channel reciprocity assumption. Then, we study the impacts of imperfect reciprocity and presence of a nearby eavesdropper on the reliability and eavesdropping resilience of the proposed scheme. Finally, we introduce an enhanced antenna index assignment algorithm which is more robust to imperfect reciprocity, and is capable of preventing a nearby eavesdropper from acquiring the transmitted bits.Index Terms -Physical layer security, MIMO wiretap channel, space shift keying.978-1-5090-5019-2/17/$31.00 ©2017 IEEE

“…Specifically in association with SM, several recently published references [2][3][4][5] have addressed the PLS issues in point-to-point communications scenarios. In more detail, the authors of [2] have analyzed the secrecy capacity of the space shift keying (SSK) assisted SM systems, when assuming communications over binary symmetric channels.…”

“…Assuming underdeterminant scenarios, the authors of [4] have proposed to exploit all the transmit antennas (TAs) for joint transmission of SM signals and jamming signals, so as to enhance the secrecy performance of the SM-MIMO systems. In [5], a general SSK modulated wiretap system has been studied, and an optimal precoding scheme has been introduced to maximize the secrecy rate of the system. In the SM scenario where precoding-aided spatial modulation (PSM) [6,7] is employed, the authors of [8] and [9] have proposed respectively the secrecy precoding and artificial noise (AN) strategies for enhancing the secrecy performance.…”

Abstract-We propose and investigate a full-duplex receiver assisted secure spatial modulation (FDR-SSM) scheme, whose security is enhanced by the jamming sent from a full-duplexing legal receiver. In our FDR-SSM system, jamming signals are designed to allow the legal receiver free from self-interference (SI), while imposing time-varying interference on the passive eavesdropper. Therefore, the FDR-SSM scheme can maintain all the advantages of spatial modulation. In this paper, the secrecy performance of the FDR-SSM system is analyzed via analyzing its ergodic secrecy rate (ESR). Furthermore, the asymptotic ESR is analyzed, when assuming that the number of transmit antennas at the legal receiver approaches infinite. Finally, performance results are provided to demonstrate the efficiency of the FDR-SSM scheme, and to verify the analytical expressions.
