Abstract
A system and method is provided for verifying an access-control policy against a particular constraint for a multi-step operation. In disclosed embodiments, the method includes expressing the access-control policy as a first quantifier-free form (QFF) constraint and identifying the particular constraint as a second QFF constraint. The method also includes identifying an operation vector and providing copies of the operation vector associated with steps in the multi-step operation. The method also includes determining a third QFF constraint using the first QFF constraint, the second QFF constraint, and the copies of the operation vector. The method also includes solving the third QFF constraint to determine a solution and outputting a result of the solving.
