1 Step-wise refinement (SWR) asserts that complex programs can be derived from simple programs by progressively adding features. The length of a program specification is the number...
We introduce a general model of refinement. This is defined in terms of what contexts an entity can appear in, and what observations can be made of it in those contexts. We show e...

Security analysis methods can provide correct yet meaningless results if the assumptions underlying the model do not conform to reality. We present an approach to analyze the secur...
