There are many obscurity enhancing techniques have been proposed based on encrypting the packets to keep the communication obscurity of Mobile Ad hoc NETworks (MANETs). However, in this paper, the authors show that MANETs are still weak under passive geometric traffic scrutiny attacks. To show how to determine the communication patterns without decrypting the captured packets, they present a novel Secure Geometric Traffic Pattern Detection System (SGTPDS). It is capable of finding the sources, the destinations and the end-to-end communication relations. SGTPDS works passively to achieve analyze the traffic based on geometric characteristics of captured raw traffic.
