A system controls policy distribution with partial evaluation to permit/deny access to protected alternatives. The system includes a database to store access control policy functions for protected alternatives, a guard to guard access to a protected alternative and construct an access control request including attributes regarding the protected alternative, a policy decider to receive the access control request from the guard, a policy distributor connected to the database and policy decider, to collect the static attributes of the protected alternative, and send them to the policy distributor, which constructs a partial access control request from the static attributes, performs partial evaluation against the stored access control policy function, resulting in a simplified access control policy function, and sends the simplified function to the policy decider, to evaluate access control requests regarding the protected alternative, and return a permit or deny response to the guard.
