Secure Distributed Hypothesis Testing
Gowtham R. Kurri, Varun Narayanan, Vinod M. Prabhakaran +1
In distributed hypothesis testing, a central server performs hypothesis testing based on information received from distributed sensors/clients. We study a secure variant of this pr…
Robust Hypothesis Testing with Abstention
Malhar A. Managoli, K. R. Sahasranand, Vinod M. Prabhakaran
We study the binary hypothesis testing problem where an adversary may potentially corrupt a fraction of the samples. The detector is, however, permitted to abstain from making a de…
Feedback Increases the Capacity of Queues with Bounded Service Times
K. R. Sahasranand, Aslan Tchamkerten
In the "Bits Through Queues" paper, it was hypothesized that full feedback always increases the capacity of first-in-first-out queues, except when the service time distribution is…
The -norm of circulant matrices via Fourier analysis
K. R. Sahasranand
A recent paper computed the induced -norm of a special class of circulant matrices , with the diagonal entries equal to …
Communication Complexity of Distributed High Dimensional Correlation Testing
K. R. Sahasranand, Himanshu Tyagi
Two parties observe independent copies of a -dimensional vector and a scalar. They seek to test if their data is correlated or not, namely they seek to test if the norm $\|ρ\|_2…
Polar Codes over Fading Channels with Power and Delay Constraints
P. K. Deekshith, K. R. Sahasranand
The inherent nature of polar codes being channel specific makes it difficult to use them in a setting where the communication channel changes with time. In particular, to be able t…
Neural Signal Multiplexing via Compressed Sensing
Nithin Nagaraj, K. R. Sahasranand
Transport of neural signals in the brain is challenging, owing to neural interference and neural noise. There is experimental evidence of multiplexing of sensory information across…
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…
A New Algorithm for Distributed Nonparametric Sequential Detection
Shouvik Ganguly, K Sahasranand, Vinod Sharma
We consider nonparametric sequential hypothesis testing problem when the distribution under the null hypothesis is fully known but the alternate hypothesis corresponds to some othe…
Sharing Graphs
K. R. Sahasranand, Nithin Nagaraj
Almost all known secret sharing schemes work on numbers. Such methods will have difficulty in sharing graphs since the number of graphs increases exponentially with the number of n…
How not to share a set of secrets
K. R. Sahasranand, Nithin Nagaraj, S. Rajan
This note analyses one of the existing space efficient secret sharing schemes and suggests vulnerabilities in its design. We observe that the said algorithm fails for certain choic…
