| Summary: | 碩士 === 國立中央大學 === 資訊工程研究所 === 95 === Since the transmitting medium of wireless sensor networks (WSNs) is the air, adversaries can easily overhear any packet “flying in the air”. In order to secure the data transmission, the general solutions are encrypting the packet payload with symmetric keys. But those algorithms only keep adversaries out of prying the content of packets and prevent the packets from being modified by adversaries. Adversaries still can learn networks topology by traffic analysis attack. In this paper, we propose an anonymous path routing (APR) protocol for WSNs. By APR protocol, the data is transmitted with anonymity between sensor nodes. Anonymous communications break the relative of the packets flying in the air. APR ensures that the adversaries cannot discover the real identities of local transmitters. The evaluation result shows that APR can achieve both anonymity and security properties of the routing protocol in WSNs. In addition, we implement our APR in the MICAz platform with TinyOS to demonstrate its applicability and communication capability in WSNs.
