Network Access and Security Issues in Ubiquitous Computing

Here are several topics that we would like to discuss and explore at the workshop. These are wireless and mobile infrastructure, security, applications and services, and mobile payments. Due to our current expertise and interest, we would like to focus on infrastructure and security issues and how problems of access, coverage, roaming, end-to-end security, reliability, location management and multicast communications could be addressed in the pervasive and ubiquitous environment.
