1 Security Issues in Mobile Ad Hoc Networks - A Survey Wenjia Li and Anupam Joshi Department of Computer Science and Electrical Engineering University of Maryland, Baltimore County Abstract In this paper, we discuss security issues and their current solutions in the mobile ad hoc network. Owe to the vulnerable nature of the mobile ad hoc network, there are numerous security threats that disturb the development of it. We first analyze the main vulnerabilities in the mobile ad hoc networks, which have made it much easier to suffer from attacks than the traditional wired network. Then we discuss the security criteria of the mobile ad hoc network and present the main attack types that exist in it. Finally we survey the current security solutions for the mobile ad hoc network. Key Words: Mobile Ad Hoc Network, Security, Intrusion Detection, Secure Routing 1. Introduction In recent years, the explosive growth of mobile computing devices, which mainly include laptops, personal digital assistants (PDAs) and handheld digital devices, has impelled a revolutionary change in the computing world: computing will not merely rely on the capability provided by the personal computers, and the concept of ubiquitous computing emerges and becomes one of the research hotspots in the computer science society [1]. In the ubiquitous computing environment, individual users utilize, at the same time, several electronic platforms through which they can access all the required information whenever and wherever they may be [2]. The nature of the ubiquitous computing has made it necessary to adopt wireless network as the interconnection method: it is not possible for the ubiquitous devices to get wired network link whenever and wherever they need to connect with other ubiquitous devices. The Mobile Ad Hoc Network is one of the wireless networks that have attracted most concentrations from many researchers. A Mobile Ad hoc NETwork (MANET) is a system of wireless mobile nodes that dynamically self-organize in arbitrary and temporary network topologies. People and vehicles can thus be internetworked in areas without a preexisting communication infrastructure or when the use of such infrastructure requires wireless extension [3]. In the mobile ad hoc network, nodes can directly communicate with all the other nodes within their radio ranges; whereas nodes that not in the direct communication range use intermediate node(s) to communicate with each other. In these two situations, all the nodes that have participated in the communication
