Abstract:
The discipline of ubiquitous computing seeks to make computing
available to a user anywhere and anytime. This requires a network
that is highly accessible, yet still secure. Current network
security mechanisms cannot be directly applied to ubiquitous
computing because of the high degree of network heterogeneity,
intermittent connectivity, the large numbers and variety of devices
as well as the high level of mobility in ubiquitous systems.
Previous attempts to provide security in ubiquitous computing have
resulted in centralised systems ill-suited to the environment. This
seminar will present an overview of current approaches to security
in a variety of networks (wired, wireless, ad-hoc, sensor and P2P).
This will be followed by a description of proposed research on a
security framework that can successfully meet the challenges
presented by ubiquitous computing. The key areas that will be
addressed in this research are: user privacy, authentication, access
control and confidentiality. The mechanisms to provide these
security services will be based on solutions from homogenous
networks, but extended to make use of user preferences and meta data
to enable more dynamic responses to security challenges. The
framework will also make use of trust relationships between entities
to facilitate interactions between entities in situations where
traditional security approaches cannot function.
