Abstract:

Research of anonymous communications has drawn much attention in both Internet community and wireless communication community. The former is more focusing on privacy preservation techniques to hide users’ communications and corresponding traffic analysis techniques to discover attackers using anonymous communication systems. The later has been mainly focused on Military uses in tactic MANET to prevent enemies from detecting and revealing communication relations between mobile nodes.

With the development of wireless technology, more and more general users adopt lightweight mobile devices in their daily life. One of promising trend is to use mobile device in cars to create Vehicular Ad Hoc Networks (VANETs). Since mobile devices are usually operated in unattended environments, they are susceptible to various network attacks. Privacy is one of major security concerns.

In this research, we investigate into the anonymous communication protocols and performance evaluation architecture in future wireless mobile Ad Hoc networks. This talk consists of four main topics:

1.    System and models of anonymous communications for mobile wireless ad hoc networks (MANETs).

2.    Anonymous communication protocols of MANETs.

3.    Traffic analysis: an IEEE 80211b based anonymous communication system.
