Critical information infrastructures (CII) include the information technologies, telecommunication, and the Internet. The protection of CII is a paramount task, as other critical infrastructures (e.g. power grids, banking, and finance) become increasingly dependent on information services. Fault tolerance, scalability, self management, and self healing are some of the main requirements for the information-based critical services. These requirements can be addressed by the emerging peer-to-peer (P2P) technologies. The P2P architectural paradigm distributes the functionality, previously centralized into servers, to all the peers into the network. This approach has the advantage of avoiding bottlenecks and single point of failure making P2P networks robust and resilient to attacks. However, decentralization and distribution of P2P systems raise t he question of trust: how to distinguish the trustworthy peers from malicious ones. In this paper we analyze the resiliency of the existing reputation-based trust management mechanisms and identify the open problems to be addressed in order to provide the degree of resiliency necessary to critical information infrastructures.
