Secure communications and data management in ubiquitous services

摘要

In the last few years, we have observed an explosive growth of ubiquitous computing, which is emerging as the next generation information technology. This new paradigm has been embodied into tremendous service models through numerous ubiquity-related technologies, such as web, ad hoc, sensor networks, and ambient intelligence to provide computing and communication services anytime and anywhere. Parallel to this, wireless communication technologies have evolved to a stage where they are capable of connecting cyber and physical domains. In such an era, computers in the traditional sense gradually fade from view, making information and communication mediated by computers available anywhere and anytime through devices that are embedded in our environment, completely interconnected, intuitive, effortlessly portable, and constantly available.
