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.
