Symmetry reduction is a model checking technique that can help alleviate the problem of state space explosion, by preventing redundant state space exploration. In previous work, we...
Live Sequence Charts (LSCs) are a broad extension to Message Sequence Charts (MSCs) to capture complex interobject communication rigorously. A tool support for LSCs, named PlayEng...
We present a model-checking algorithm which can be used to evaluate access control policies, and a tool which implements it. The evaluation includes not only assessing whether the ...
We present a model of access control which provides fine-grained data-dependent control, can express permissions about permissions, can express delegation, and can describe syste...

We present a simple formulation of Assumption-Commitment reasoning using CSP. In our formulation, an assumption-commitment style property of a process SYS takes the form COM SYS A...
