Abstract :
A wireless ad hoc network is subject to various security attacks including traffic analysis. In this paper, we explore the approach of preventing traffic analysis through hiding the source and destination of packets. We argue that Chaum´s (1981) mix method and proposed security schemas (IPSec (Kent et al. (1998)), Onion Routing (Reed et al. (1998)), and Non Disclosure Method (Fasbender et al. (1996))) cannot adapt to the dynamic changes of topology in a wireless ad hoc network and may cause network performance degradation. A dynamic mix method is proposed which attempts to improve the network performance while still hiding the source and destination of packets.
