Security Architecture for Mobile Adhoc Networks
Banita Chadha, B. Tech Student · 2011
Although security issues in Mobile Ad-hoc NETworks (MANETs) have been a major focus in the recent years, the development of most secure schemes for these networks has not been entirely achieved till now. This paper summarizes three main technical contributions about “Security Architecture for Wireless Ad hoc Networks”. This paper will provide an overview of two of the most important security problems in MANETs: Authentication and Cooperation. In an ad hoc network there is no supporting infrastructure like base stations, access points or wireless switching centers. The two main conclusions of our research are that authentication issues that have to be taken into account with a global vision at the first stage of any network formation, and that a good cooperative enforcement scheme seems to be the best solution to the selshness problem. A general description of functionalities in each layer is given and we analyze the security mechanisms in military applications in the scope of the proposed security architecture.
