+We discuss the security implications in pesudonymity systems throughout
+this paper. Most attacks on pseudonymity systems fall into one of the
+following categories.
+
+Legal and hacking attacks. Attackers may attempt to coerce the operators
+of pseudonymity systems through lawsuits or other means, or may attempt to
+surreptitiously obtain information about nym-holders. Systems should be
+designed so that such information cannot be obtained.
+
+Mix attacks. Systems based on the mix-net primative must be concerned with
+attacks against the underlying mix-network, as they rely upon it for
+security. Additionally, reply-block-based nym server systems require
+additional security properties that normal mix-net systems may not
+have~\cite{minx}.
+
+Replay attacks. An attacker capable of monitoring the communications
+network may attempt to obtain information about nym holders by comparing
+network and user behavior when a given message or packet is transmitted
+multiple times.
+
+Who am I? attack. An attacker may send messages intended for nym Alice
+intended fo nym Bob, in order to confirm that Alice and Bob are the same
+nym-holder~\cite{gd-thesis}.
+
+Usage pattern and intersection attacks. An attacker may analyze network
+usage and anonymity set members over time to sub-divide anonymity sets
+such that a given user is identified.
+
+Statistical-disclosure attacks.
