Abstract:

In heterogeneous information systems, some access control techniques and policies were adopted to protect the resources. It was necessary to coordinate security policies between interconnected enterprises. By this way the information could be shared effectively. A primitive ticket-based authorization model was proposed to manage disparate policies in information enclaves. The formal description and the computation of the privilege were also given.

Key words: heterogeneity, security policy, coordination, ticket, token
