Algorithmic aspects of security auditing among multi agents to acquire trust access control in hybrid cloud

Abstract

Distributed cloud computing provides finest solutions in solving business challenges like exchange of information technology resources with various infrastructure providers, infinite scalability, integrity and agility. On the same line, cloud technology is also associated with the major concerns like security, privacy and trust computing with respect to applications and information which are hosted in cloud environment. Due to existence of large number of cloud service providers and infrastructure providers there certain downfall in concerned to trust factors of consumers and data owners. Current existing trusted cloud environment is seriously affected with service deployment overhead due to huge number of applications that are compatible for mobile applications and as well as desktop applications. An efficient operation is a key success to manage cloud heterogeneity as it is a primary factor to serve users. newlineIn this work, we propose a swarm based decision model to evaluate the trustworthiness of cloud service providers. The model is designed on three simple rules separation, convergence and aggregation feedback. The trust model checks with uncertainty probability due to various services deliver parameters like probability ratio based on user trust threshold, rejection rates and workloads. In this thesis trust is subjected with subjective opinion over the consideration of federated cloud environment. The resources that are shared among different infrastructures utility may totally lack in trust considerations, to asses these kinds of situations the cloud characteristics are subjected as dimensions. The dimensions are conceptualized with opinion of cloud entity satisfying following criteria s as follows Reputation, Credibility, Cloud Service Provider ratings and Parameters of Service level agreements.
