Acimn: A protocol for Anonymous Communication In Multi hop wireless networks

Fusenig, V., Spiewak, D. and Engel, T.

While communicating wireless every node residing in communication range of the sending node is able to eavesdrop the communication. The content of the messages can be kept confidential by encryption. On the other hand the communication partners are still known. Even if no personal information like source and destination address is included in the message an attacker might reveal the communication partners with the help of traffic analysis. In this paper the Acimn protocol is introduced which enables anonymous communication in multi hop wireless networks. It bases on the combination of the dining cryptographers networks and layered encryption. Both, the message overhead and the overhead due to cryptographic algorithms, is kept small while the protocol offers protection against traffic analysis attacks.
