New Covert Channels in HTTP
This paper presents new methods enabling anonymous ommuni ation on the Internet. We des ribe a new proto ol that allows us to reate an anonymous overlay network by exploiting the web browsing a tivities of regular users. We show that the overlay network provides an anonymity set greater than the set of senders and re eivers in a realisti threat model. In parti ular, the proto ol provides unobse...
متن کاملExploiting Temporal Persistence to Detect Covert Botnet Channels
We describe a method to detect botnet command and control traffic and individual end-hosts. We introduce the notion of ”destination traffic atoms” which aggregate the destinations and services that are communicated with. We then compute the ”persistence”, which is a measure of temporal regularity and that we propose in this paper, for individual destination atoms. Very persistent destination at...
متن کاملCovert Channels | Here to Stay? Covert Channels | Here to Stay?
We discuss the di culties of satisfying high-assurance system requirements without sacri cing system capabilities. To alleviate this problem, we show how trade-o s can be made to reduce the threat of covert channels. We also clarify certain concepts in the theory of covert channels. Traditionally, a covert channel's vulnerability was measured by the capacity. We show why a capacity analysis alo...

متن کاملA New Class of Decentralized Interaction Estimators for Load Frequency Control in Multi-Area Power Systems
Load Frequency Control (LFC) has received considerable attention during last decades. This paper proposes a new method for designing decentralized interaction estimators for interconnected large-scale systems and utilizes it to multi-area power systems. For each local area, a local estimator is designed to estimate the interactions of this area using only the local output measurements. In fact,...
