      Singh, Prabhjot (University of Waterloo, 2024-01-24)
      Although encrypted channels, like those provided by anonymity networks such as Tor, have been put into effect, network adversaries have proven their capability to undermine users' browsing privacy through website fingerprinting ...
    • Website Fingerprinting: Attacks and Defenses 

      Wang, Tao (University of Waterloo, 2016-01-13)
      Website fingerprinting attacks allow a local, passive eavesdropper to determine a client's web activity by leveraging features from her packet sequence. These attacks break the privacy expected by users of privacy technologies, ...
    • Weighting Document Genre in Enterprise Search 

      Yeung, Peter Chun Kai (University of Waterloo, 2007-08-14)

    • Which classes of structures are both pseudo-elementary and definable by an infinitary sentence? 

      Boney, Will; Csima, Barbara F.; Day, Nancy A.; Harrison-Trainor, Matthew (2019-03-21)
      When classes of structures are not first-order definable, we might still try to find a nice description. There are two common ways for doing this. One is to expand the language, leading to notions of pseudo-elementary ...
