A wireless, mobile, ad hoc network (MANET) is a network in which mobile nodes do
not rely on the existence of fixed infrastructure mediation devices, but rather
communicate with one another directly. Under certain scenarios, parties in a
MANET may wish to remain unidentified, in order to forestall retaliation by an
attacker. In this talk, we discuss mechanisms for anonymous routing in MANETs.
First, we note threats to anonymity in MANETs, derive a general adversary model
and use it to define anonymity in a formal yet intuitive manner. Then, we use
our framework to analyze the anonymity of existing routing algorithms under
various identity agreements which we define. Lastly, we briefly compare our
results with those of others. The talk is self-contained.
