A Novel Policy Integration Management Model Based on Mapping Mechanism for Heterogeneous Environment

To solve the problems of policy compatibility which are caused by the multiple heterogeneous policies that were used in a single virtual organization, a new policy mapping model is proposed. The model mapped the local policies to Ponder policy objects which be instanced with different parameters based on Ponder policy language. Each type policy is defined as a policy base class, each policy base class can dynamically generate one or more execution class with requirements and multiple execution class overloaded based on different parameters. The testing results of the prototype system show that the model can realize the unified management of heterogeneous policies and can contribute to the implementation of safety management through the trusted computing technology.
