An Efficient Advantage Distillation Scheme for Bidirectional Secret-Key Agreement SCIE
期刊论文 | 2017 , 19 (9) | ENTROPY | IF: 2.305
Abstract&Keyword Cite

Abstract :

The classical secret-key agreement (SKA) scheme includes three phases: (a) advantage distillation (AD), (b) reconciliation, and (c) privacy amplification. Define the transmission rate as the ratio between the number of raw key bits obtained by the AD phase and the number of transmitted bits in the AD. The unidirectional SKA, whose transmission rate is 0.5, can be realized by using the original two-way wiretap channel as the AD phase. In this paper, we establish an efficient bidirectional SKA whose transmission rate is nearly 1 by modifying the two-way wiretap channel and using the modified two-way wiretap channel as the AD phase. The bidirectional SKA can be extended to multiple rounds of SKA with the same performance and transmission rate. For multiple rounds of bidirectional SKA, we have provided the bit error rate performance of the main channel and eavesdropper's channel and the secret-key capacity. It is shown that the bit error rate (BER) of the main channel was lower than the eavesdropper's channel and we prove that the transmission rate was nearly 1 when the number of rounds was large. Moreover, the secret-key capacity Cs was from 0.04 to 0.1 as the error probability of channel was from 0.01 to 0.15 in binary symmetric channel (BSC). The secret-key capacity was close to 0.3 as the signal-to-noise ratio increased in the additive white Gaussian noise (AWGN) channel.

Abstract :

Physical layer security in slow fading wiretap channels is often guaranteed by constraining the secrecy outage probability (SOP) below a maximum tolerable value. In this paper, we propose a new nonadaptive (NADP) transmission scheme for maximizing the secrecy throughput by using adjustable transmit power based on the instantaneous channel state information (CSI) of the main channel under an SOP constraint. To solve this problem, we transform the optimization problem to single-variable maximization problems in two cases, and the quasiconcavity of them is proved which allows us to use the Golden Section Method (GSM) to find the optimal solution. Simulation results are provided and verify that the proposed NADP scheme is superior to the existing one especially when the transmit power is high.

Abstract :

The artificial noise (AN) aided beamforming design in the MISOME (multiple-input, single-output, multiple-avesdropper) wiretap channel is studied from the perspective of secrecy outage. Unlike many existing works which directly adopted the traditional null-space AN scheme, we start with a general assumption on the structure of the transmit signal, and seek to find the optimal structure by solving a secrecy outage probability (SOP) constrained secrecy rate maximization problem. By generalizing several existing conclusions regarding a single-antenna eavesdropper, we prove that the null-space AN scheme is indeed optimal for an arbitrary number of the eavesdropper's antennas from the perspective of secrecy outage. The power allocation problem is also studied and the closed-form optimal solution is obtained. It is found that the increase in the eavesdropper's antenna number is equivalent to requiring a smaller SOP.

Abstract :

This paper proposes a new nonadaptive (NADP) transmission scheme with adjustable power allocation based on the instantaneous channel state information (CSI) of the main channel for the multiple-input-single-output-single-eavesdropper (MISOSE) system. With the assistance of the adjustable power allocation ratio, we can improve the secure transmission performance under the constraints of secrecy outage probability (SOP) and upper bound rate (UBR). To verify the superiority of our new approach, we consider the multi-antenna communication systems with NADP scheme and give the optimal solution for achieving the maximum secrecy throughput based on a two-dimensional (2-D) searching method. In addition, a good suboptimal solution is also provided to reduce the time complexity of the optimal solution. Simulation results are provided and confirm that the proposed NADP scheme has significant advantages over the existing work especially when the transmit power is high.

Abstract :

This paper studies the artificial noise (AN) aided secure transmission design in a multiple-input-single-output multicast channel where a common message is transmitted to multiple receivers and only statistical channel state information of the eavesdropper is available. In this scenario, there may be no valid null space which allows the AN not to affect the legitimate receivers, and the traditional null-space AN scheme may not be applicable. To find the optimal design, we formulate a secrecy outage probability (SOP) constrained secrecy rate maximization problem which applies to an arbitrary number of the receivers. We adopt a novel approximation of the intractable SOP constraint and establish an efficient algorithm which solves the approximated problem to global optimality. The effectiveness of AN as well as the proposed solution is confirmed by simulation results. It is shown that the AN aided approach performs much better than pure beamforming even when there is no valid null space.

Abstract :

In this paper, we investigate the physical-layer security of slow fading wiretap channel with channel estimation errors. We aim to maximize the reliable secrecy rate under constraints of secrecy outage probability and reliability outage probability. To this end, we propose an adaptive (ADP) transmission scheme in which the communication rate and secrecy rate are adaptively adjusted based on the estimated imperfect channel state information (CSI) of the legitimate channel. The optimal solution is obtained by solving a single-variable maximization problem, where the objective function is log-concave. Numerical results are provided to verify our approach as well as to show the impact of imperfect CSI on the secrecy throughput.

Abstract :

The opportunistic cooperation schemes, where only the "best" relay is selected to forward the message, have been widely investigated recently for their good performance in terms of outage probability. However, the unfair selections of relays may cause unbalance power consumptions among relays, which reduces the lifetime of energy constrained networks. In this paper, we introduce a novel concept of outage priority based fairness (OPF), aiming at improving the selection fairness among relays appropriately without outage performance deterioration. Then, a cooperation scheme is proposed to meet this concept,. and corresponding theoretical analysis is also provided. Afterward, based on OPF, the achievable upper bound of the fairness is derived, and an optimal cross-layer designed scheme is also provided to achieve the bound. Numerical simulations are carried out finally, which not only validate the theoretical analysis, but also show that taking advantages of the proposed schemes, the fairness among all relays, as well as the network lifetime, can be greatly improved without any loss of outage performance, especially in high SNR regime.

Abstract :

In this paper, we propose a family of space-time block codes (STBC) that achieve full diversity when linear receivers, such as zero-forcing (ZF) or minimum mean square error (MMSE) receivers, are used. Our proposed STBC family is a combination/overlay between orthogonal STBC and Toeplitz codes, which can be viewed as a generalization of overlapped Alamouti codes (OAC) and Toeplitz codes recently proposed in the literature. Simulation results show that the newly proposed STBC may outperform the existing codes when linear receivers are used.

A Distributed Linear Convolutive Space-Frequency Coding for Cooperative Communication Systems with Multiple Frequency Offsets EI CPCI-S Scopus

Abstract :

Multiple frequency offsets (CFO) in cooperative communications are difficult, if not impossible, to compensate completely at the destination node. The multiple CFO make the channel time-varying, and thus the conventional space-time codes to collect diversity gain for co-located multi-input multi-output (MIMO) systems may not be applied directly. In a previous paper, we proposed a distributed space-frequency code (SFC), called frequency-reversal SFC (FR-SFC), for cooperative transmissions with multiple CFOs and flat fading channels. We have shown that this code can achieve the full cooperative diversity with only linear receivers, such as zero-forcing (ZF) and minimum mean square error (MMSE) receivers. However, the code is not bandwidth efficient when the relay nodes are more than 3. To have a higher bandwidth efficiency, in this paper we propose a new distributed SFC called frequency-domain linear convolutive SFC(FLC-SFC). The symbol rates of the new codes approach 1 when code block length is sufficiently larger than the number of relay nodes. Furthermore. It achieves the full cooperative diversity with linear receivers.

Abstract :

In cooperative communications, due to the distributed nature, multiple different carrier frequency offsets (CFOs) may occur and make the channel time-varing. It is hard for the receiver to compensate multiple CFOs from multiple relay nodes simultaneously. Thus, the conventional space-time codes to collect cooperative diversity for co-located multi-input multi-output (MIMO) systems may not be applied directly. In this paper, we consider the cooperative transmission with multiple CFOs when the channels from relay nodes to destination node are flat (frequency-non-selective) fading. We approximate a flat fading channel with CFO as a block time-invariant intersymbol-interference (ISI) channel in the frequency domain. We then propose two distributed space-frequency codes (SFC) for such ISI channels in the frequency domain to achieve the cooperative full spatial diversity, where the space-frequency coding concept is different from the one in the literature and also has a different role. One is called frequency-reversal SFC and the other is called frequency-domain linear convolutive SFC. Furthermore, we show that, with only linear receivers, such as zero-forcing (ZF) and minimum mean square error (MMSE) receivers, our codes achieve the full cooperative diversity.
