摘要：Ad-hoc networks are a new paradigm of wireless communication for mobile hosts. There are various challenges that are faced in the Ad-hoc environment. These are mostly due to the resource poorness of these networks. They are usually set up in situations of emergency, for temporary operations or simply if there are no resources to set up elaborate networks. Ad-hoc networks therefore throw up new requirements and problems in all areas of networking. The solutions for conventional networks are usually not sufficient to provide efficient Ad-hoc operations. The wireless nature of communication and lack of any security infrastructure raise several security problems. One of the important issue is that an ad hoc wireless network permits wireless mobile nodes to communicate without prior infrastructure. Due to the limited range of each wireless node, communication sessions between two nodes are usually established through a number of intermediate nodes. Unfortunately, some of these intermediate nodes might be malicious, forming a threat to the security or confidentiality of exchanged data. While data encryption can protect the content exchanged between nodes, analysis of communication patterns may reveal valuable information about end users and their relationships. Using anonymous paths for communication provides security and privacy against traffic analysis. To establish these anonymous paths, all nodes build a global view of the network by exchanging routing information. In this paper we focus on Ad hoc routing and we present a secure anonymous route discovery protocol for Ad hoc routing in Ad hoc wireless networks
