Covert Adversarial Actuators in Finite MDPs
Edoardo David Santi, Gongpu Chen, Deniz Gündüz +1
We consider a Markov decision process (MDP) in which actions prescribed by the controller are executed by a separate actuator, which may behave adversarially. At each time step, th…
PIR Over Wireless Channels: Achieving Privacy With Public Responses
Or Elimelech, Asaf Cohen
In this paper, we address the problem of Private Information Retrieval (PIR) over a public Additive White Gaussian Noise (AWGN) channel. In such a setup, the server's responses are…
On PIR and SPIR Over Gaussian MAC
Or Elimelech, Asaf Cohen
This paper revisits the problems of Private Information Retrieval (PIR) and Symmetric PIR (SPIR). In PIR, a user retrieves a desired message from replicated, non-communicating…
Correction to "Private Information Retrieval Over Gaussian MAC"
Or Elimelech, Ori Shmuel, Asaf Cohen
In the above article \cite{shmuel2021private}, the authors introduced a PIR scheme for the Additive White Gaussian Noise (AWGN) Multiple Access Channel (MAC), both with and without…
