When visiting a web page, a sequence of request-response transactions will be introduced. On one hand, the browser issues requests for objects in order. On the other hand, the server responses with required object contents. This makes the traffic of a specified web page demonstrate pattern features different from other pages. Traffic analysis techniques can extract these features to identify web pages effectively even if the traffic is encrypted. In this paper, we propose a countermeasure method, psOBJ, to defend against traffic analysis by introducing pseudo-objects in browser-server communications. We compose some object fragments into a constructed object, the pseudo-object, and force the object requests and responses on pseudo-objects. By randomly composing pseudo-objects with different number of object fragments with different sizes, the traffic for a given web page could be variable and exhibits different traffic patterns in different visits. We have implemented a proof of concept prototype and validate the psOBJ countermeasure with some state of the art traffic analysis techniques. |
