Certificate Revocation to Cope with False Accusations in Mobile Ad Hoc Networks

摘要: In Mobile Ad hoc NETworks (MANETs), certification systems play an important role in maintaining network security because attackers can freely move and repeatedly launch attacks against different nodes. By adopting systems, it becomes possible to exclude identified from the permanently by revoking certifications of attackers. A simple way identify is collect information on nodes network. However, this approach, difficult differentiate valid accusations made legitimate false malicious addition, amount traffic order exchange necessary time gather increases as size larger. paper, we propose a certificate revocation scheme which revoke short with small operating traffic. clustering introducing multi-level node reliability, proposed mitigate improper due users.
