Distortion based Light-weight Security for Cyber-Physical Systems
Gaurav Kumar Agarwal, Mohammed Karmoose, Suhas Diggavi +2
In Cyber-Physical Systems (CPS), inference based on communicated data is of critical significance as it can be used to manipulate or damage the control operations by adversaries. T…
On Secure Network Coding for Multiple Unicast Traffic
Gaurav Kumar Agarwal, Martina Cardone, Christina Fragouli
This paper investigates the problem of secure communication in a wireline noiseless scenario where a source wishes to communicate to a number of destinations in the presence of a p…
On Secure Capacity of Multiple Unicast Traffic over Separable Networks
Gaurav Kumar Agarwal, Martina Cardone, Christina Fragouli
This paper studies the problem of information theoretic secure communication when a source has private messages to transmit to destinations, in the presence of a passive advers…
Distorting an Adversary's View in Cyber-Physical Systems
Gaurav Kumar Agarwal, Mohammed Karmoose, Suhas Diggavi +2
In Cyber-Physical Systems (CPSs), inference based on communicated data is of critical significance as it can be used to manipulate or damage the control operations by adversaries.…
Secure Communication over 1-2-1 Networks
Gaurav Kumar Agarwal, Yahya H. Ezzeldin, Martina Cardone +1
This paper starts by assuming a 1-2-1 network, the abstracted noiseless model of mmWave networks that was shown to closely approximate the Gaussian capacity in [1], and studies sec…
A Distortion Based Approach for Protecting Inferences
Chi-Yo Tsai, Gaurav Kumar Agarwal, Christina Fragouli +1
Eavesdropping attacks in inference systems aim to learn not the raw data, but the system inferences to predict and manipulate system actions. We argue that conventional information…
On (Secure) Information flow for Multiple-Unicast Sessions: Analysis with Butterfly Network
Gaurav Kumar Agarwal, Martina Cardone, Christina Fragouli
This paper considers a class of wireline networks, derived from the well-known butterfly network, over which two independent unicast sessions take place simultaneously. The main ob…
On Secure Network Coding for Two Unicast Sessions
Gaurav Kumar Agarwal, Martina Cardone, Christina Fragouli
This paper characterizes the secret message capacity of three networks where two unicast sessions share some of the communication resources. Each network consists of erasure channe…
Codes With Hierarchical Locality
Birenjith Sasidharan, Gaurav Kumar Agarwal, P. Vijay Kumar
In this paper, we study the notion of {\em codes with hierarchical locality} that is identified as another approach to local recovery from multiple erasures. The well-known class o…
A High-Rate MSR Code With Polynomial Sub-Packetization Level
Birenjith Sasidharan, Gaurav Kumar Agarwal, P. Vijay Kumar
We present a high-rate -MSR code with a sub-packetization level that is polynomial in the dimension of the code. While polynomial sub-packetization level was achie…
An Alternate Construction of an Access-Optimal Regenerating Code with Optimal Sub-Packetization Level
Gaurav Kumar Agarwal, Birenjith Sasidharan, P. Vijay Kumar
Given the scale of today's distributed storage systems, the failure of an individual node is a common phenomenon. Various metrics have been proposed to measure the efficacy of the…
