We present a static analysis that infers both upper and lower bounds on the usage that a logic program makes of a set of user-definable resources. The inferred bounds will in gener...
We describe the design and implementation of a trust-management system Soutei, a dialect of Binder, for access control in distributed systems. Soutei policies and credentials are w...
The semantics of constraint logic programming languages with coroutining facilities (\freeze," suspension, residuation, etc.) cannot be fully declarative; thus, an operationa...
Distributed Description Logics (DDL) is a KR formalism that enables reasoning with multiple ontologies interconnected by directional semantic mapping. Subsumption propagation in DD...
The security policy of an information system may include a wide range of different requirements. The literature has primarily focused on access and information flow control require...
