A crucial task in process management is the validation of process refinements. A process refinement is a process description in a more fine-grained representation. The refinement i...
Abstract. Just as cooperation in multi-agent systems is a central issue for solving complex tasks, so too is the ability for an intelligent agent to reason about combined knowledge...
We present a novel reasoning calculus for the Description Logic SHIQ. In order to reduce the nondeterminism due to general inclusion axioms, we base our calculus on hypertableau an...
We prove that, if the initial knowledge of the intruder is given by a deterministic bottom-up tree automaton, then the insecurity problem for cryptographic protocols with atomic ke...
Growing attention is being paid to application security at requirements engineering time. Confidentiality is a particular subclass of security concerns that requires sensitive inf...
