Secure anonymous routing in ad hoc networks

Communication in Ad Hoc networks relies on the routing functionality of the intermediate nodes. Secure routing and preventing traffic analysis are important criterion for secure anonymous communication in Ad Hoc networks. By analyzing the traffic in ad hoc networks, the location and identity of the nodes can be found thereby losing anonymity. A number of techniques are available for anonymous routing. Existing techniques are vulnerable to packet type analysis attacks thus do not provide complete anonymity and security. Also they involve more cryptographic overhead. We propose a secure anonymous communication system for Ad Hoc networks involving less cryptographic operations and also addressing various drawbacks in existing techniques providing complete anonymity.
