Securing the Madeira network management system

In the research project Madeira a meshed network management system based on P2P technologies was developed. Event though, up to date, security has always been neglected in this field of research despite the sensitivity of such systems and the high number of security threats that affect them, Madeira incorporates a security solution aimed at minimizing the identified highest-priority risks on all levels. This solution introduces a distributed certification authority based on threshold cryptography, certificate revocation list distribution points and a collaborative accusation protocol aimed at uncovering hosts that exhibit illegal or unwanted behaviour while avoiding false accusations from a malicious node.
