摘要：In computer science distributed systems could be more secured with a distributed trust model based on PKI. PKI provides a framework to verify the identities of each entities of given domain. 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 w ith a pervasive public key infrastructure (pervasive-PKI). This choice allows the validation of credentials of users roa ming between heterogeneous networks, even w hen global connectivity is lost and some services are temporarily unreachable. Proof-of- concept implementations and test bed 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 dynamic and collaborative trust model, use of attribute certificates for privilege management, and modular architecture enabling nomadic mobility and enhanced with reconfiguration capabilities.
