Cloud Armor: a platform for credibility-based trust management of cloud services

Trust management of cloud services is emerging as an important research issue in recent years, which poses significant challenges because of the highly dynamic, distributed, and non-transparent nature of cloud services. This paper describes Cloud Armor, a platform for credibility-based trust management of cloud services. The platform provides a crawler for automatic cloud services discovery, an adaptive and robust credibility model for measuring the credibility of feedbacks, and a trust-based recommender to recommend the most trustworthy cloud services to users. This paper presents the motivation, system design, implementation, and a demonstration of the Cloud Armor platform.
