SYSTEM AND METHOD PROVIDING INTEROPERABILITY BETWEEN ENFORCED POLICIES

摘要

The present invention relates to a method and system for providing interoperability between policies. In one aspect of the invention, a controller (22a, 22b) is assigned to each agent (24a, 24b) which are communicating with one another. The controller includes a list of policies (Lp) to which each agenter can interoperate. A message is exported from a first controller under a first law for enforcing a first policy. The message is imported at the second agent under a second law for enforcing a second policy if the message identifier to the first policy is in the list of policies to which the second agent can operate. In addition, the method of the present invention provides a secure implementation of interoperability by applying a verifiable authentication to the message before exporting the message from the first controller and the verifiable authentication is verified at the second controller. The method and system can be used to provide inter-enterprise electronic commerce, for example, in a purchase order transaction.
