 I'd like to evaluate on Tor security metrics that are based on adversary
 models. Some adversary models to consider are
 1. An adversary that can compromise k relays.
 2. An adversary that can contribute b bandwidth.
 3. An adversary that can observe k Autonomous Systems.
 The security metrics for Tor based on these models that are relevant to
 Tor include
 1. The probability that the adversary observes the entry and exit traffic
 of a given connection.
 2. The probability distribution of the number of connections of a user for
 which the adversary observes entry and exit traffic (guard selection is
 particularly important here).
 3. The "linkability" of different connections.
