Abstract:

I will discuss the evolution of ubiquitous computing. Future ubiquitous communications systems will enable interaction between an increasingly diverse range of devices, both mobile and fixed. This will allow users to construct their own ubiquitous services using a combination of different communications technologies. Dynamic, heterogeneous and distributed networks will create new opportunities, such as the convergence of communications and highly adaptive reconfigurable terminals. They will also bring new challenges. I will discuss the particular problems involved in securing such ubiquitous environments. My goal is to establish a series of requirements for future security architectures, and future directions that might lead towards the ubiquitous utopia.
