Secrecy Throughput of MANETs Under Passive and Active Attacks
Mobile Ad hoc NETworks (MANETs) represent one of the most innovative emerging networking technologies, with broad potential applications in personal area networks, emergency and rescue operations, military applications, etc. The unique features of MANETs, such as mobility and peer-to-peer connectivity, make MANETs a very flexible technology for establishing communication in areas with limited infrastructure. In this paper, the authors propose to achieve secure communication over MANETs via an approach developed based on information-theoretic security. The idea is to apply the powerful secure coding developed in information-theoretic security to preprocess messages being transmitted through the network to guarantee secure communication in the presence of malicious nodes.
