Abstract:ost real-life systems delegate responsibilities to
di�erent authorities. We apply this model to a dig-
ital rights management system, to achieve
security. In our model a hierarchy of authorities
issues certi�cates that are linked by cryptographic
means. This linkage establishes a chain of control,
identity-attribute-rights, and allows
exible rights
control over content. Typical security objectives,
such as identi�cation, authentication, authoriza-
tion and access control can be realised. Content
keys are personalised to detect illegal super distri-
bution. We describe a working prototype, which
we develop using standard techniques, such as stan-
dard certi�cates, XML and Java. We present ex-
perimental results to evaluate the scalability of the
system. A formal analysis demonstrates that our
design is able to detect a form of illegal super dis-
