Conditional Delegation Model Based on Weighted Roles for Workflow

For the limitation of current workflow delegation models, a conditional delegation model based on weighted roles for workflow is proposed. For the model, it is supporting conditional partial delegation by adding weights to roles and importing variables in workflow tasks. The role delegation tree is defined to address the multi-step delegation issue, and the consistency delegation checking method is provided. Based on this model, the corresponding delegation and revocation algorithm is also given. Finally, a simple example is given, which demonstrates the delegation working process and the building process of role delegation tree.
