We consider what portions of the policy state must be monitored to detect violations of integrity constraints. Then we address the fact that not all participants in a trust management system can be trusted to assist in such monitoring, and show how many integrity constraints can be monitored in a conservative manner so that trusted participants detect and report if the system enters a policy state from which evolution in unmonitored portions of the policy could lead to a constraint violation.An extended abstract appears in the proc. of the 10th ACM Symp. on Access Control Models and Technologies (SACMAT). 2005Cryptography and SecurityDatabasesK.6.5; D.4.6text
