A Workflow Criticality-Based Approach to Bypass the Workflow Satisfiability Problem

Monsef Boughrous, Hanan El Bakkali, Chien Ming Chen
2021 Security and Communication Networks  
For this purpose, we define workflow criticality, which can be used as a metric during run-time to prevent WSP.  ...  As a result, the number of available and authorized users for the workflow execution decreases drastically.  ...  Moreover, the authors showed that finding an optimal role-based authorization policy that allows a workflow execution is NPcomplete.  ...
