Timing channels in traffic analysis
"We study two timing channel problems abstracted from practices of network traffic analysis. The first timing channel exists in a router receiving packets from two users; due to the sharing of router buffer, queuing delays of one user's packets incidentally convey information about the other user's …

An Information-Theoretic and Game-Theoretic Study of Timing Channels
Jammers which have quantized batch departures at regular intervals are shown to perform well. Batch inputs at regular intervals perform well for maximum delay constrained or maximum buffer size constrained jammers, while batch inputs with batch arrival times chosen at random perform well for …

Identifying the origins of business’ data breaches utilizing covert timing channels
… efficiently and from multiple locations. Covert timing channels are a cybersecurity attack method in which malicious actors embed privileged information into normal network traffic without authorization. Malicious actors, by carefully manipulating timing patterns in covert timing channels, can …

Detection of data leakage and disruption of covert timing channel in secure drone communication using machine and deep learning
… the detectability and disruptability of covert timing channel traffic in secure drones. The investigation aims to ascertain the effects of multiple interarrival times, distances ranging from 1 to 330 feet, various detection algorithms, and stream sizes between 32-bit and 256-bits on the …

Graph-based decoders and divergence-rate estimators for data-hiding problems
… of multimedia blind watermark decoding and timing channels steganalysis. The central problem considered, loosely speaking, is that of implementing optimal (or near-optimal) strategies at the receiver, which is typically tasked to perform reliable decoding or detection, depending on the …

Achievable rates for queue-based timing stegocodes
… codes) for covert communication over timing channels. In a timing channel, the information resides in the packet interdeparture times as opposed to the packets themselves. The en- coding procedure should preserve the statistics of the packet interarrival process. Our steganographic …

Defending against side-channel attacks : DynamoREA
… about their applications through side-channels caused by micro-architectural side-effects. Through these side-channels, attackers can launch timing attacks by observing how long an application takes to execute and using this timing information to exfiltrate secrets from the application. …

Efficient and Verifiable Timing Channel Protection for Multi-Core Processors
… systems are becoming increasingly vulnerable to timing channel attacks that leak confidential information through the timing of microarchitectural events. Many timing channel attacks are caused by the interference between different programs in the shared resources of a multi-core processor. For …
