摘要: Two classes of nominal automata, namely Usage Automata (UAs) and Variable Finite (VFAs) are considered to express resource control policies over program execution traces expressed by a calculus (Usages). We first analyse closure properties UAs, then show UAs less expressive than VFAs. finally carry VFAs the symbolic technique for model checking Usages against so making it possible verify compliance with larger class security properties.
