The MPEG-DASH streaming video standard contains an information leak: even if the stream
is encrypted, the segmentation prescribed by the standard causes content-dependent …

When multiple job processes are served by a single scheduler, the queueing delays of one
process are often affected by the others, resulting in a timing side channel that leaks the …

Anonymous communication, where users communicate without revealing the identities of
communicating parties or the paths of data flow is critical in data networks. On the Internet …

Anonymous systems on the Internet aim to protect users from revealing to an external

We study a covert queueing channel (CQC) between two users sharing a round robin
scheduler. Such a covert channel can arise when users share a resource such as a …

Information security requires the protection of not only the contents of data transmitted but
also the timing of network operations. Knowledge of timing alone can reveal to an adversary …

In this paper, we consider fair privacy in a shared network subject to traffic analysis attacks
by an eavesdropper. We initiate the study of the joint trade-off between privacy, throughput …

Resource sharing while preserving privacy is an increasingly important problem due to a
wide-scale adoption of cloud computing. Under multitenancy, it is common to have multiple …

Abstract Information security requires the protection of, not only the contents of data
transmitted, but also the timing of packet transmissions in a network. Knowledge of timing …
