Performance Analysis of a MIMO System with Bursty Traffic in the presence of Energy Harvesting Jammer
Sujatha Allipuram, Parthajit Mohapatra, Nikolaos Pappas +2
This paper explores the role of multiple antennas in mitigating jamming attacks for the Rayleigh fading environment with exogenous random traffic arrival. The jammer is assumed to…
On the Secrecy Capacity of 2-user Gaussian Z-Interference Channel with Shared Key
Somalatha U, Parthajit Mohapatra
In this paper, the role of secret key with finite rate is studied to enhance the secrecy performance of the system when users are operating in interference limited scenarios. To ad…
Secure Status Updates under Eavesdropping: Age of Information-based Physical Layer Security Metrics
He Chen, Qian Wang, Parthajit Mohapatra +1
This letter studies the problem of maintaining information freshness under passive eavesdropping attacks. The classical three-node wiretap channel model is considered, in which a s…
Secure Communications for the Two-user Broadcast Channel with Random Traffic
Parthajit Mohapatra, Nikolaos Pappas, Jemin Lee +2
In this work, we study the stability region of the two-user broadcast channel (BC) with bursty data arrivals and security constraints. We consider the scenario, where one of the re…
Outer Bounds on the Secrecy Capacity Region of the 2-user Z Interference Channel With Unidirectional Transmitter Cooperation
Parthajit Mohapatra, Chandra R. Murthy, Jemin Lee
This paper derives outer bounds on the secrecy capacity region of the 2-user Z interference channel (Z-IC) with rate-limited unidirectional cooperation between the transmitters. Fi…
On the Secrecy Capacity Region of the 2-user Z Interference Channel with Unidirectional Transmitter Cooperation
Parthajit Mohapatra, Chandra R. Murthy, Jemin Lee
In this work, the role of unidirectional limited rate transmitter cooperation is studied in the case of the 2-user Z interference channel (Z-IC) with secrecy constraints at the rec…
