Research Collaborations
The DBIS Group is conducting research in collaboration with various
other faculty and research institutions (on campus and off campus).
Computer Security
In collaboration with the Computer Security Laboratory
at the CS Department, we are studying several aspects of security
policies. This includes the development of security specification
languages for different types of applications and scenarios with a
particular forcus on highly heteroegeneous and distributed computing
enviroments. Further aspects that are studied in this framework are
the dynamics of security policies, systems and trust relationships
among components (services and agents) in distributed computing
environments.

Software Engineering
We are studing information system
infrastructures that support the software configuration process. Our
particular interest is in developing trusted mediation services in
which a client can specify trust preferences on the software
configuration information to be obtained from Web sources through a
mediated framework. Current results include (1) an infrasturucture
for managing trust information about Web source and data and
providing using trust agencies and trust brokers, (2) a trust model
which can be used by clients to transparently specify trust
requirements on data to be obtained from data sources, and (3)
mediation algorithms which are used by the mediator in order to
integrate information from data sources according to trust
preferences specified by a client.
