Controlled inter-carrier interference for physical layer security in OFDM systems
Yusuf, Marwan; Arslan, Hüseyin (Institute of Electrical and Electronics Engineers Inc., 2016)Performance of OFDM is known to be very sensitive to frequency synchronization errors. By exploiting this feature, a novel technique is proposed to provide secure communication against eavesdropping. The technique is based ... -
Cross MAC/PHY layer security design using ARQ with MRC and adaptive modulation
Hamamreh, Jehad M.; Yusuf, Marwan; Baykaş, Tuncer; Arslan, Hüseyin (Institute of Electrical and Electronics Engineers Inc., 2016)In this work, Automatic-Repeat-Request (ARQ) and Maximal Ratio Combination (MRC), have been jointly exploited to enhance the confidentiality of wireless services requested by a legitimate user (Bob) against an eavesdropper ... -
Enhancing physical-layer security in wireless communications using signal space diversity
Yusuf, Marwan; Arslan, Hüseyin (Institute of Electrical and Electronics Engineers Inc., 2016)In this paper, we enhance the security of OFDM systems in frequency selective fading channels using signal space diversity. In rich multipath environments, spatially separated channels are independent to each other. Hence, ... -
On signal space diversity: An adaptive interleaver for enhancing physical layer security in frequency selective fading channels
Yusuf, Marwan; Arslan, Hüseyin (Elsevier Science Bv, 2017)Signal space diversity is a powerful technique that increases reliability of detection over fading channels. In this paper, we explore the ability of this technique to provide secure communication. We enhance the security ... -
Physical layer security schemes for wireless communication systems
Yusuf, Marwan (İstanbul Medipol Üniversitesi Fen Bilimleri Enstitüsü, 2016)Security in wireless communications has always been a major concern due to the broadcast nature of the radio waves. Apart from the conventional cryptologic methods that are performed in the upper layers, physical-layer ... -
Secure spatial multiple access using directional modulation
Hafez, Mohammed; Yusuf, Marwan; Khattab, Tamer; Elfouly, Tarek; Arslan, Hüseyin (IEEE-Institute of Electrical and Electronics Engineers Inc, 2018)In this paper, we introduce a secure multiple access scheme, which exploits the multipath structure of the channel to create a multi-user interference environment. The generated interference enables legitimate users to ...
