abstract = {In the last years, trust management has become a fundamental basis for facilitating the cooperation between different users in peer-to-peer (P2P) multimedia applications within autonomic networks. In these networks and applications, trust management should fulfill certain requirements (i.e. decentralisation, dynamism, simplicity, interoperability, etc.) for being functional. In this paper, we propose an evolutionary model of trust management that captures dynamic entities’ behaviour over time. Likewise, we explain protection mechanisms against several attacks, which are based on the cooperative behaviour of the entities, trust relationship properties, and trust rules. Finally, we successfully validate our model from several scenarios and compare it with other proposals in this field.},

abstract = {Network and device heterogeneity, nomadic mobility, intermittent connectivity and, more generally, extremely dynamic operating conditions, are major challenges in the design of security infrastructures for pervasive computing. Yet, in a ubiquitous computing environment, limitations of traditional solutions for authentication and authorization can be overcome with a pervasive public key infrastructure (pervasive-PKI). This choice allows the validation of credentials of users roaming between heterogeneous networks, even when global connectivity is lost and some services are temporarily unreachable. Proof-of-concept implementations and testbed validation results demonstrate that strong security can be achieved for users and applications through the combination of traditional PKI services with a number of enhancements like: (i) dynamic and collaborative trust model, (ii) use of attribute certificates for privilege management, and (iii) modular architecture enabling nomadic mobility and enhanced with reconfiguration capabilities.},
