Secure interactions between administrative domains are modeled. The modeled process specifies role information for each of the administrative domains and interaction between the administrative domains. Role information associated with candidate administrative domains is received, and appropriate administrative domains from the candidate administrative domains are dynamically resolved based on the modeled process and the received role information. Trust realms between the dynamically resolved appropriate administrative domains are automatically derived based on the role information and the interactions from the modeled process. The secure interaction between the dynamically resolved appropriate administrative domains is effected through the automatically derived trust realms.
