TAILIEUCHUNG - Security in Ad Hoc Networks

SAFE is a comprehensive, robust security blueprint based on Cisco AVVID (Architecture for Voice, Video and Integrated Data). The SAFE blueprint consists of modules that address the distinct requirements of each network area. By adopting a SAFE blueprint, security managers do not need to redesign the entire security architecture each time a new service is added to the modular templates, securing each new service as it is needed and integrating it with the overall security architecture is easier and more cost effective. SAFE is the first industry blueprint that recommends exactly which security solutions should be included in which sections of the network and why. | Security in Ad Hoc Networks Vesa Karpijoki Helsinki University of Technology Telecommunications Software and Multimedia Laboratory Abstract In ad hoc networks the communicating nodes do not necessarily rely on a fixed infrastructure which sets new challenges for the necessary security architecture they apply. In addition as ad hoc networks are often designed for specific environments and may have to operate with full availability even in difficult conditions security solutions applied in more traditional networks may not directly be suitable for protecting them. A short literature study over papers on ad hoc networking shows that many of the new generation ad hoc networking proposals are not yet able to address the security problems and they face. Environment-specific implications on the required approaches in implementing security in such dynamically changing networks have not yet fully realized. 1 Introduction An ad hoc network is a collection of nodes that do not need to rely on a predefined infrastructure to keep the network connected. Ad hoc networks can be formed merged together or partitioned into separate networks on the fly without necessarily relying on a fixed infrastructure to manage the operation. Nodes of ad hoc networks are often mobile which also implicates that they apply wireless communication to maintain the connectivity in which case the networks are called as mobile ad hoc networks MANET . Mobility is not however a requirement for nodes in ad hoc networks in ad hoc networks there may exist static and wired nodes which may make use of services offered by fixed infrastructure. Ad hoc networks may be very different from each other depending on the area of application For instance in a computer science classroom an ad hoc network could be formed between students PDAs and the workstation of the teacher. In another scenario a group of soldiers is operating in a hostile environment trying to keep their presence and mission .
