Webtiming attacks over a remote connection is comparable to that of a sequential timing attack on the local system. Through a formal model, we show how concurrency-based timing attacks are theoretically unaffected by jitter on the network connection. We then show how these attacks can be applied in practice in a variety of scenarios: web appli- WebTiming attacks are related to a class of attacks called side-channel attacks.
