Abstract
A reference monitor that authorizes information flows between elements of a data processing system is provided. The elements of the data processing system are associated with security data structures in a reference monitor. An information flow request is received from a first element to authorize an information flow from the first element to a second element. A first security data structure associated with the first element and a second security data structure associated with the second element are retrieved. At least one set theory operation is then performed on the first security data structure and the second security data structure to determine if the information flow from the first element to the second element is to be authorized. The security data structures may be labelsets having one or more labels identifying security policies to be applied to information flows involving the associated element.
