Modeling of MULTI SAFE Protection Enforcement Processes with Extended Petri Nets
1981) Modeling of MULTI SAFE Protection Enforcement Processes with Extended Petri Nets. Technical Report CS81005-R, Computer Science, Virginia Tech. (
The various kinds of access decision dependency within a predicate-based model of database protection are classified according to cost of enforcement. Petri nets and some useful extensions are described. Extended Petri nets are used to model the flow of messages and data during protection enforcement within MULTISAFE, a multimodule system architecture for secure database management. The model demonstrates that stated criteria for security are met within MULTISAFE. Of particular interest is the modeling of data dependent access conditions with predicates at Petri net transitions.
