An Information Theoretic Study of Timing Side Channels in Two-user Schedulers
Xun Gong, Negar Kiyavash, Parv Venkitasubramaniam
Timing side channels in two-user schedulers are studied. When two users share a scheduler, one user may learn the other user's behavior from patterns of service timings. We measure…
Mitigating Timing Side Channel in Shared Schedulers
Sachin Kadloor, Negar Kiyavash, Parv Venkitasubramaniam
In this work, we study information leakage in timing side channels that arise in the context of shared event schedulers. Consider two processes, one of them an innocuous process (r…
An Improvement to Levenshtein's Upper Bound on the Cardinality of Deletion Correcting Codes
Daniel Cullina, Negar Kiyavash
We consider deletion correcting codes over a q-ary alphabet. It is well known that any code capable of correcting s deletions can also correct any combination of s total insertions…
Invisible Flow Watermarks for Channels with Dependent Substitution, Deletion, and Bursty Insertion Errors
Xun Gong, Mavis Rodrigues, Negar Kiyavash
Flow watermarks efficiently link packet flows in a network in order to thwart various attacks such as stepping stones. We study the problem of designing good flow watermarks. Earli…
