Crowds

Crowds

Crowds is a proposed anonymity network that gives probable innocence in the face of a large number of attackers. Crowds was designed by Michael K. Reiter and Aviel D. Rubin and defends against internal attackers and a corrupt receiver, but provides no anonymity against a global attacker or a local eavesdropper (see "Crowds: Anonymity For Web Transactions"). Crowds is vulnerable to the predecessor attack; this was discussed in Reiter and Rubin's paper and further expanded in "The Predecessor Attack: An Analysis of a Threat to Anonymous Communications Systems" by Matthew K. Wright, Micah Adler, And Brian Neil Levine. Crowds introduced the concept of users blending into a crowd of computers. Provide users with a mechanism for anonymous Web browsing. The main idea behind Crowds anonymity protocol is to hide each user's communications by routing them randomly within a group of similar users. By Crowds protocol a corrupt group member or local eavesdropper that observes a message being sent by a particular user can never be sure whether the user is the actual sender, or is simply routing another user's message.

Famous quotes containing the word crowds:

    “Although crowds gathered once if she but showed her face,
    And even old men’s eyes grew dim, this hand alone,
    Like some last courtier at a gypsy camping-place
    Babbling of fallen majesty, records what’s gone.”
    —William Butler Yeats (1865–1939)

    “Good-bye, proud world! I’m Going home;
    Thou art not my friend, and I’m not thine.
    Long through thy weary crowds I roam;
    A river-ark on the ocean brine,”
    —Ralph Waldo Emerson (1803–1882)
