Blind secure communication: The Secure degrees of freedom of one hop wireless networks with No CSI
Amir M.; Khattab T. ( Institute of Electrical and Electronics Engineers Inc. , 2018 , Conference Paper)We study a number of wireless networks with secrecy constraints and No CSI. The wiretap and MIMO broadcast channels in a presence of an external eavesdropper and the MIMO interference channel with secret messages and no ... -
Joint coding for proactive caching with changing file popularities
Amir M.; Bedeer E.; Ahmed M.H.; Khattab T. ( Institute of Electrical and Electronics Engineers Inc. , 2018 , Conference Paper)Proactive caching is a promising technique used to minimize peak traffic rates by storing popular data, in advance, at different nodes in the network. We study a cellular network with one base station (BS) communicating ... -
Secrecy for MIMO wiretap and MIMO broadcast channels with fading eavesdroppers: CSI does not increase the secure DoF
Amir M.; Khattab T.; Elfouly T.; Mohamed A. ( Institute of Electrical and Electronics Engineers Inc. , 2015 , Conference Paper)We investigate the secure degrees of freedom (SDoF) of the wiretap and the K user Gaussian broadcast channels with multiple antennas at the transmitter, the legitimate receivers and an unknown number of eavesdroppers each ... -
Secure DoF for the MIMO MAC: The case of knowing eavesdropper's channel statistics only
Amir M.; Khattab T.; Yaacoub E.; Abualsaud K.; Guizani M. ( Institute of Electrical and Electronics Engineers Inc. , 2019 , Conference Paper)Physical layer security has attracted research attention as a means to achieve secure communication without the need for complicated upper layer encryption techniques. The secure degrees of freedom (SDoF) of various networks ...
