Partial Strong Converse for the Non-Degraded Wiretap Channel
Yi-Peng Wei, Sennur Ulukus
We prove the partial strong converse property for the discrete memoryless \emph{non-degraded} wiretap channel, for which we require the leakage to the eavesdropper to vanish but al…
Secrecy in MIMO Networks with No Eavesdropper CSIT
Pritam Mukherjee, Sennur Ulukus
We consider two fundamental multi-user channel models: the multiple-input multiple-output (MIMO) wiretap channel with one helper (WTH) and the MIMO multiple access wiretap channel…
The Capacity of Private Information Retrieval from Coded Databases
Karim Banawan, Sennur Ulukus
We consider the problem of private information retrieval (PIR) over a distributed storage system. The storage system consists of non-colluding databases, each storing a coded v…
Covert Bits Through Queues
Pritam Mukherjee, Sennur Ulukus
We consider covert communication using a queuing timing channel in the presence of a warden. The covert message is encoded using the inter-arrival times of the packets, and the leg…
MIMO Wiretap Channel under Receiver Side Power Constraints with Applications to Wireless Power Transfer and Cognitive Radio
Karim Banawan, Sennur Ulukus
We consider the multiple-input multiple-output (MIMO) wiretap channel under a minimum receiver-side power constraint in addition to the usual maximum transmitter-side power constra…
Secure Degrees of Freedom of the Multiple Access Wiretap Channel with Multiple Antennas
Pritam Mukherjee, Sennur Ulukus
We consider a two-user multiple-input multiple-output (MIMO) multiple access wiretap channel with antennas at each transmitter, antennas at the legitimate receiver, and …
