While no countermeasures would completely protect people from such invasion, the authors propose a method for redesigning browsers to prevent the majority of timing attacks. Even that solution, however, is imperfect and does not prevent maliciously designed sites from inserting some forms of dummy addresses into a Web browser's cache and looking them up later. Nonetheless, the researchers believe that domain tagging could work sufficiently well to assure Web users a reasonable level of privacy.
