Covert timing channels
WebFeb 4, 2013 · Covert timing channel attacks—Timing attacks are difficult to detect and function by altering a component or by modifying resource timing. Covert storage channel attacks—These attacks use one process to write data to a storage area and another process to read the data. Here is an example of how covert channel attacks happen in real life. WebIn this paper, we propose CoCo, a novel framework for establishing covert timing channels. The CoCo covert channel modulates the covert message in the inter-packet delays of the network flows, while a coding algorithm is used to ensure the robustness of the covert message to different perturbations. The CoCo covert channel is adjustable: by ...
