Abstract. We present a formal system that models programmable abstractions for access control. Composite abstractions and patterns of arbitrary complexity are modeled as a configu...
We formally specify a payment protocol described in [Vogt et al., 2001]. This protocol is intended for fair exchange of time-sensitive data. Here the µCRL language is used to form...
An increasingly important trend in the engineering of complex systems is the design of component integration standards. Such standards de ne rules of interaction and shared commun...
