A framework for covert and secret key expansion over quantum channels
Mehrdad Tahmasbi, Matthieu R. Bloch
Covert and secret quantum key distribution aims at generating information-theoretically secret bits between distant legitimate parties in a manner that remains provably undetectabl…
Multilevel-Coded Pulse-Position Modulation for Covert Communications over Binary-Input Discrete Memoryless Channels
Ishaque Ashar Kadampot, Mehrdad Tahmasbi, Matthieu R Bloch
We develop a low-complexity coding scheme to achieve covert communications over binary-input discrete memoryless channels (BI-DMCs). We circumvent the impossibility of covert commu…
Covert Capacity of Non-Coherent Rayleigh-Fading Channels
Mehrdad Tahmasbi, Anne Savard, Matthieu R. Bloch
The covert capacity is characterized for a non-coherent fast Rayleigh-fading wireless channel, in which a legitimate user wishes to communicate reliably with a legitimate receiver…
Learning an Adversary's Actions for Secret Communication
Mehrdad Tahmasbi, Matthieu R. Bloch, Aylin Yener
Secure communication over a wiretap channel is investigated, in which an active adversary modifies the state of the channel and the legitimate transmitter has the opportunity to se…
