Abstract

A dramatic increase in the number of devices that are connected to the wireless networks has seen many challenging issues.One of them is the security problem.Enhancement in physical layer security has shown promising results to improve these security issues in the existing wireless networks.This paper proposes a transmission technique based on scrambled Bose Chaudhuri Hocquenghem code with feedback to improve the physical layer security in wireless communication system.The security of the transmission system over a wiretap channel is investigated.Scrambling matrix is applied to the code word and a hybrid automatic repeat request (HARQ) protocol is used.In this paper, the security gap is used as a performance metric to measure the difference between the authorized and unauthorized channel.We find that the proposed technique results in smaller security gap compared to the conventional techniques.

Improving wireless physical layer security via co-operative techniques

Security is a critical concern in wireless network. Physical layer security exploits the physical characteristics of wireless channel for secure transmission. The physical layer security approach is a competitive alternative to achieve information-theoretic secrecy. In the area of physical layer security which guarantees confidentiality by using Automatic Repeat Request technique, ARQ is described in a general way that includes its use over a wide range of underlying physical medium. Physical layer security focuses on exploiting the physical layer properties of the wireless channels to protect the confidential information transmission against eavesdropping. It describes the electric or optical signals used for communicating between two computers. Here a physical layer security technique is adopted for secret key distribution. In this improving physical layer based security for wireless network using jamming technique in automatic repeat request has been implemented. The automatic repeat request (ARQ) mechanism is a well-known technique to handle transmission errors, when data is transmitted over noisy channels. This service describes sending and receiving information with possible confirmation. The result obtained gives the performance of the increased signal to noise ratio and the decreased bit error rate and the mean square error.

Coding With Scrambling, Concatenation, and HARQ for the AWGN Wire-Tap Channel: A Security Gap Analysis

Marco Baldi, Marco Bianchi, Franco Chiaraluce

This paper examines the use of nonsystematic channel codes to obtain secure transmissions over the additive white Gaussian noise wire-tap channel. Unlike the previous approaches, we propose to implement nonsystematic coded transmission by scrambling the information bits, and characterize the bit error rate of scrambled transmissions through theoretical arguments and numerical simulations. We have focused on some examples of Bose-Chaudhuri-Hocquenghem and low-density parity-check codes to estimate the security gap, which we have used as a measure of physical layer security, in addition to the bit error rate. Based on a number of numerical examples, we found that such a transmission technique can outperform alternative solutions. In fact, when an eavesdropper (Eve) has a worse channel than the authorized user (Bob), the security gap required to reach a given level of security is very small. The amount of degradation of Eve's channel with respect to Bob's that is needed to achieve sufficient security can be further reduced by implementing scrambling and descrambling operations on blocks of frames, rather than on single frames. While Eve's channel has a quality equal to or better than that of Bob's channel, we have shown that the use of a hybrid automatic repeat-request protocol with authentication still allows achieving a sufficient level of security. Finally, the secrecy performance of some practical schemes has also been measured in terms of the equivocation rate about the message at the eavesdropper and compared with that of ideal codes.

The analysis of secure HARQ with chase combining over block fading channel

Yue Wu, Lukman Abiodun Olawoyin, Nana Zhang +1 more

In this letter, the physical layer security of hybrid automatic repeat request with chase combining (HARQ-CC) scheme is investigated from the viewpoint of information theory. Different from the literature which used Wyner code, our analysis focuses on the general scenario without specific code. We firstly obtain the outage probability of both main channel and wiretap channel. Since retransmissions are completely determined by main channel, we then prove that its achievable diversity order equals to maximum transmission number (K) while this order of wiretap channel is only one. Furthermore, we evaluate the metric of secure gap which demonstrates the difference between main channel and wiretap channel with reliable and secure constraints. As K increases, the secure gap decreases monotonously. When K is large enough, the security can be guaranteed even if wiretap channel is better than main channel.

Increasing physical layer security through reliability-based HARQ

Qinyu Zou, Bangning Zhang, Yanqing Ma +1 more

In this paper, we proposed a secure communication scheme based on Reliability-Based Hybrid Automatic Repeat reQuest (RB-HARQ) protocol over the additive white Gaussian noise (AWGN) wiretap channel. RB-HARQ protocol aims at retransmitting the unreliable bits required for the authorized user's (Bob) successfully decoding and minimizing the information leakage that may benefit to eavesdropper (Eve). The secrecy level in this paper is assessed through the bit error rate (BER) at both the authorized user (Bob) and eavesdropper (Eve). Therefore, we analyze the BER of our proposed scheme through theoretical arguments and simulations. Numerical results suggest that RB-HARQ protocol can significantly enhance the security performance of our communication system.

Non-systematic codes for physical layer security

Marco Baldi, Marco Bianchi, Franco Chiaraluce

This paper is a first study on the usage of non-systematic codes based on scrambling matrices for physical layer security. The chance of implementing transmission security at the physical layer is known since many years, but it is now gaining an increasing interest due to its several possible applications. It has been shown that channel coding techniques can be effectively exploited for designing physical layer security schemes, in such a way that an unauthorized receiver, experiencing a channel different from that of the authorized receiver, is not able to gather any information. Recently, it has been proposed to exploit puncturing techniques in order to reduce the security gap between the authorized and unauthorized channels. In this paper, we show that the security gap can be further reduced by using non-systematic codes, able to scramble information bits within the transmitted codeword.
