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 with a pervasive-Public Key Infrastructure (pervasive-PKI).
