Secure State Estimation against Sensor Attacks in the Presence of Noise
Shaunak Mishra, Yasser Shoukry, Nikhil Karamchandani +2
We consider the problem of estimating the state of a noisy linear dynamical system when an unknown subset of sensors is arbitrarily corrupted by an adversary. We propose a secure s…
Secure State Estimation: Optimal Guarantees against Sensor Attacks in the Presence of Noise
Shaunak Mishra, Yasser Shoukry, Nikhil Karamchandani +2
Motivated by the need to secure cyber-physical systems against attacks, we consider the problem of estimating the state of a noisy linear dynamical system when a subset of sensors…
Effect of Number of Users in Multi-level Coded Caching
Jad Hachem, Nikhil Karamchandani, Suhas Diggavi
It has been recently established that joint design of content delivery and storage (coded caching) can significantly improve performance over conventional caching. This has also be…
Opportunistic Scheduling for Full-Duplex Uplink-Downlink Networks
Can Karakus, Suhas Diggavi
We study opportunistic scheduling and the sum capacity of cellular networks with a full-duplex multi-antenna base station and a large number of single-antenna half-duplex users. Si…
On the Oblivious Transfer Capacity of the Degraded Wiretapped Binary Erasure Channel
Manoj Mishra, Bikash Kumar Dey, Vinod M. Prabhakaran +1
We study oblivious transfer (OT) between Alice and Bob in the presence of an eavesdropper Eve over a degraded wiretapped binary erasure channel from Alice to Bob and Eve. In additi…
Matched Multiuser Gaussian Source-Channel Communications via Uncoded Schemes
Chao Tian, Jun Chen, Suhas Diggavi +1
We investigate whether uncoded schemes are optimal for Gaussian sources on multiuser Gaussian channels. Particularly, we consider two problems: the first is to send correlated Gaus…
