dc.description.abstract | The proliferation of mobile hand-held devises and the development of ad-hoc
networking technologies has opened the possibility for users of these devises
to partake in collaborative applications with other mobile users. The sharing of
resources and information within these groups will maximise the experience
for all group members. This will require a user of the system to grant access
to local resources to other users, some of whom may be semi or completely
unknown. The major issue that affects the user of the collaborative ad-hoc
application is how can they grant access to a user who is completely unknown
to them.
People are able interact with others who are semi or completely unknown to
them in many every day situations, the extent to which they interact is
governed by the concept of trust. Trust is a complicated model that allows
people to balance the risk of the unknown against the perceived benefits of
interaction. The aim of this dissertation is to investigate if a model for trust
production can be integrated into a computer access control mechanism to
manage interaction with anonymous users.
A mechanism will be developed that will produce a trust value for any user
based on the details of previous interactions between the two or
recommendations. An dynamic trust-based access control system, which
binds minimum trust levels to access right will then be used to verify if an
unknown user is trusted enough to gain access to the users resources. A
blackjack card game that uses a trust-based access control system to assign
roles to users was implemented in java, JINI technology was used to
distribute the application. | en |
