Data-Driven Optimization of Directed Information over Discrete Alphabets
Dor Tsur, Ziv Aharoni, Ziv Goldfeld +1
Directed information (DI) is a fundamental measure for the study and analysis of sequential stochastic models. In particular, when optimized over input distributions it characteriz…
Pufferfish Privacy: An Information-Theoretic Study
Theshani Nuradha, Ziv Goldfeld
Pufferfish privacy (PP) is a generalization of differential privacy (DP), that offers flexibility in specifying sensitive information and integrates domain knowledge into the priva…
k-Sliced Mutual Information: A Quantitative Study of Scalability with Dimension
Ziv Goldfeld, Kristjan Greenewald, Theshani Nuradha +1
Sliced mutual information (SMI) is defined as an average of mutual information (MI) terms between one-dimensional random projections of the random variables. It serves as a surroga…
Neural Estimation and Optimization of Directed Information over Continuous Spaces
Dor Tsur, Ziv Aharoni, Ziv Goldfeld +1
This work develops a new method for estimating and optimizing the directed information rate between two jointly stationary and ergodic stochastic processes. Building upon recent ad…
The Secrecy Capacity of Cost-Constrained Wiretap Channels
Sreejith Sreekumar, Alexander Bunin, Ziv Goldfeld +2
In many information-theoretic channel coding problems, adding an input cost constraint to the operational setup amounts to restricting the optimization domain in the capacity formu…
Capacity of Continuous Channels with Memory via Directed Information Neural Estimator
Ziv Aharoni, Dor Tsur, Ziv Goldfeld +1
Calculating the capacity (with or without feedback) of channels with memory and continuous alphabets is a challenging task. It requires optimizing the directed information (DI) rat…
Information Storage in the Stochastic Ising Model
Ziv Goldfeld, Guy Bresler, Yury Polyanskiy
Most information storage devices write data by modifying the local state of matter, in the hope that sub-atomic local interactions stabilize the state for sufficiently long time, t…
Wiretap and Gelfand-Pinsker Channels Analogy and its Applications
Ziv Goldfeld, Haim. H. Permuter
An analogy framework between wiretap channels (WTCs) and state-dependent point-to-point channels with non-causal encoder channel state information (referred to as Gelfand-Pinker ch…
Key and Message Semantic-Security over State-Dependent Channels
Alexander Bunin, Ziv Goldfeld, Haim H. Permuter +3
We study the trade-off between secret message (SM) and secret key (SK) rates, simultaneously achievable over a state-dependent (SD) wiretap channel (WTC) with non-causal channel st…
Fourier-Motzkin Elimination Software for Information Theoretic Inequalities
Ido B. Gattegno, Ziv Goldfeld, Haim H. Permuter
We provide open-source software implemented in MATLAB, that performs Fourier-Motzkin elimination (FME) and removes constraints that are redundant due to Shannon-type inequalities (…
MIMO Gaussian Broadcast Channels with Common, Private and Confidential Messages
Ziv Goldfeld, Haim H. Permuter
The two-user multiple-input multiple-output (MIMO) Gaussian broadcast channel (BC) with common, private and confidential messages is considered. The transmitter sends a common mess…
Wiretap Channels with Random States Non-Causally Available at the Encoder
Ziv Goldfeld, Paul Cuff, Haim H. Permuter
We study the state-dependent (SD) wiretap channel (WTC) with non-causal channel state information (CSI) at the encoder. This model subsumes all other instances of CSI availability…
Arbitrarily Varying Wiretap Channels with Type Constrained States
Ziv Goldfeld, Paul Cuff, Haim H. Permuter
An arbitrarily varying wiretap channel (AVWTC) with a type constraint on the allowed state sequences is considered, and a single-letter characterization of its correlated-random (C…
Strong Secrecy for Cooperative Broadcast Channels
Ziv Goldfeld, Gerhard Kramer, Haim H. Permuter +1
A broadcast channel (BC) where the decoders cooperate via a one-sided link is considered. One common and two private messages are transmitted and the private message to the coopera…
Semantic-Security Capacity for Wiretap Channels of Type II
Ziv Goldfeld, Paul Cuff, Haim H. Permuter
The secrecy capacity of the type II wiretap channel (WTC II) with a noisy main channel is currently an open problem. Herein its secrecy-capacity is derived and shown to be equal to…
Broadcast Channels with Privacy Leakage Constraints
Ziv Goldfeld, Gerhard Kramer, Haim H. Permuter
The broadcast channel (BC) with one common and two private messages with leakage constraints is studied, where leakage rate refers to the normalized mutual information between a me…
Duality of a Source Coding Problem and the Semi-Deterministic Broadcast Channel with Rate-Limited Cooperation
Ziv Goldfeld, Haim H. Permuter, Gerhard Kramer
The Wyner-Ahlswede-Körner (WAK) empirical-coordination problem where the encoders cooperate via a finite-capacity one-sided link is considered. The coordination-capacity region is…
The Finite State MAC with Cooperative Encoders and Delayed CSI
Ziv Goldfeld, Haim H. Permuter, Benjamin M. Zaidel
In this paper, we consider the finite-state multiple access channel (MAC) with partially cooperative encoders and delayed channel state information (CSI). Here partial cooperation…
