    • Channel secondary random process for robust secret key generation 

      Badawy A.; Khattab T.; Elfouly T.; Chiasserini C.-F.; Mohamed A.; ... more authors ( Institute of Electrical and Electronics Engineers Inc. , 2015 , Conference Paper)
      The broadcast nature of wireless communications imposes the risk of information leakage to adversarial users or unauthorized receivers. Therefore, information security between intended users remains a challenging issue. ...

    • Robust secret key extraction from channel secondary random process 

      Badawy A.; Elfouly T.; Khattab T.; Chiasserini C.-F.; Mohamed A.; ... more authors ( John Wiley and Sons Ltd , 2016 , Conference Paper)
      The vast majority of existing secret key generation protocols exploit the inherent randomness of the wireless channel as a common source of randomness. However, independent noise added at the receivers of the legitimate ...

    • Taking advantage of multi-user diversity in OFDM systems 

      Oviedo, Jose Armando; Sadjadpour, Hamid R.; Guizani, Mohsen (2013 , Conference Paper)
      A multi-user diversity approach, called Opportunistic Interference Management (OIM), is considered in connection with Orthogonal Frequency Division Multiplexing (OFDM) systems. The OIM is applied to each consecutive group ...
