Dsss With ISAKMP Key Management Protocol to Secure Physical Layer for Mobile Adhoc Network

Free registration required

Executive Summary

The wireless and dynamic nature of Mobile Ad hoc NETworks (MANETs) leaves them more vulnerable to security attacks than their wired counterparts. The nodes act both as routers and as communication end points. This makes the physical layer more prone to security attacks. The MANET physical layer is challenging to DoS attack and also some passive attacks. The physical layer protocol in MANETs is responsible for bit-level transmission between network nodes. The proposed model combines spread spectrum technology Direct Sequence Spread Spectrum (DSSS) with key management technique ISAKMP to defend against signal jamming denial-of-service attacks in physical layer of MANET.
