摘要: Encryption is often proposed as a tool for protecting the privacy of World Wide Web browsing. However, encryption-particularly typically implemented in, or in concert with popular browsers-does not hide all information about encrypted plaintext. Specifically, HTTP object count and sizes are revealed (or at least incompletely concealed). We investigate identifiability traffic based on this unconcealed large sample pages, show that it suffices to identify significant fraction them quite reliably. also suggest some possible countermeasures against exposure kind experimentally evaluate their effectiveness.
