A Novel Side-Channel in Real-Time Schedulers
Chien-Ying Chen, Sibin Mohan, Rodolfo Pellizzoni +2
We demonstrate the presence of a novel scheduler side-channel in preemptive, fixed-priority real-time systems (RTS); examples of such systems can be found in automotive systems, av…
REORDER: Securing Dynamic-Priority Real-Time Systems Using Schedule Obfuscation
Chien-Ying Chen, Monowar Hasan, AmirEmad Ghassami +2
The deterministic (timing) behavior of real-time systems (RTS) can be used by adversaries - say, to launch side channel attacks or even destabilize the system by denying access to…
Fundamental Limits of Database Alignment
Daniel Cullina, Prateek Mittal, Negar Kiyavash
We consider the problem of aligning a pair of databases with correlated entries. We introduce a new measure of correlation in a joint distribution that we call cycle mutual informa…
Analysis of a Canonical Labeling Algorithm for the Alignment of Correlated Erdős-Rényi Graphs
Osman Emre Dai, Daniel Cullina, Negar Kiyavash +1
Graph alignment in two correlated random graphs refers to the task of identifying the correspondence between vertex sets of the graphs. Recent results have characterized the exact…
Counting and Sampling from Markov Equivalent DAGs Using Clique Trees
AmirEmad Ghassami, Saber Salehkaleybar, Negar Kiyavash +1
A directed acyclic graph (DAG) is the most common graphical model for representing causal relationships among a set of variables. When restricted to using only observational data,…
Nonparametric Hawkes Processes: Online Estimation and Generalization Bounds
Yingxiang Yang, Jalal Etesami, Niao He +1
In this paper, we design a nonparametric online algorithm for estimating the triggering functions of multivariate Hawkes processes. Unlike parametric estimation, where evolutionary…
Fairness in Supervised Learning: An Information Theoretic Approach
AmirEmad Ghassami, Sajad Khodadadian, Negar Kiyavash
Automated decision making systems are increasingly being used in real-world applications. In these systems for the most part, the decision rules are derived by minimizing the train…
