An Effective Way of Evaluating Trust in Inter-cloud Computing

Kiran Mary Matthew, Abdul Quadir Md
2017 International Journal of Computer Network and Information Security  
This is accomplished through trust management systems that calculate the trust rating of clouds from opinions from their peers.  ...  This paper proposes a method to reduce such problems by considering the latest history of communication of a particular cloud and ignore the opinions given by less trusted clouds.  ...  Each broker is responsible for all the resources in its domain. Accuracy concept is used to enable peer review-based mechanisms to function with imprecise trust metrics.  ...
