Anonymous MANET Routing: Traffic Analysis and Cross-Layer MANET Design

Research in anonymous routing has been explored in both wired and wireless networking environments. Many MANET anonymous routing solutions borrow the ideas from wired networking environment such as Mix-nets. They adopted the methods by using on-demand routing, and packet re-encryption on each packet forwarding hop to hide the linkable information, i.e., the source/destination communication relation. However, in wireless environments, the adversaries can explore the communication relations by deploying traffic analysis attacks. As a result, the anonymity protections deployed at the network layer cannot effectively prevent the adversaries from disclosing the transmission relations. The main reason is the substrate layers can expose enough information to help the adversaries to exploit the transmission relations. Thus, in order to provide a secure and anonymous solution, we should refer cross-layer approach to device anonymous routing protocols. Our current research focuses on three directions: (1) traffic analysis attacks, (2) anonymity modeling and evaluation, and (3) cross-layer anonymous routing protocols.
