Achieving Shannon Capacity Region as Secrecy Rate Region in a Multiple Access Wiretap Channel
Shahid Mehraj Shah, Vinod Sharma
We consider a two user multiple-access channel with an eavesdropper at the receiving end. We use previously transmitted messages as a key in the next slot till we achieve the capac…
Distributed Nonparametric Sequential Spectrum Sensing under Electromagnetic Interference
Sahasranand K. R., Vinod Sharma
A nonparametric distributed sequential algorithm for quick detection of spectral holes in a Cognitive Radio set up is proposed. Two or more local nodes make decisions and inform th…
Algorithms for Stochastic Games on Interference Channels
Krishna Chaitanya A, Utpal Mukherji, Vinod Sharma
We consider a wireless channel shared by multiple transmitter-receiver pairs. Their transmissions interfere with each other. Each transmitter-receiver pair aims to maximize its lon…
Previous Messages Provide the Key to Achieve Shannon Capacity in a Wiretap Channel
Shahid Mehraj Shah, Parameswaran S, Vinod Sharma
We consider a wiretap channel and use previously transmitted messages to generate a secret key which increases the secrecy capacity. This can be bootstrapped to increase the secrec…
Achieving Shannon Capacity in a Wiretap Channel via Previous Messages
Shahid Mehraj Shah, Vinod Sharma
In this paper we consider a wiretap channel with a secret key buffer. We use the coding scheme of [1] to enhance the secrecy rate to the capacity of the main channel, while storing…
