Distributed Quantitative Information Flow Evaluation for Service Composition in Clouds

摘要: Service composition provides a promising way for the delivery of IT applications to satisfy complex consumers' demands. The qualitative information flow control mechanism based on non-interference solid security assurance propagation customer's private data across multiple service providers. However, strict discipline limits availability and may cause high failure rate composition. Therefore, we propose distributed quantitative evaluation approach clouds. us more precise evaluate leakage supports customized disciplines diverse requirements different customers. Through experiments proof, results indicate that our can improve composite effectively with affordable costs while satisfying requirements.
