Item Trusted path between two entities in Cloud(Institute of Electrical and Electronics Engineers Inc., 2016) Divakarla, U.; Chandrasekaran, K.Trust plays an important role in the security of resources of the emerging technology called Cloud. To develop a strong trust there has to be a strong trust path between two entities. In cloud, trust plays a major role as the basic services between the user and service provider is due to the trust. Our paper proposes scheme to build a strong trust path between two important entities in cloud namely user and resources of the service provider. The performance analysis proves that the proposed model platform independent and also much stronger in case of migration and more efficient in terms of computation time. © 2016 IEEE.Item A novel approach for evaluating trust of resources in cloud environment(Institute of Electrical and Electronics Engineers Inc., 2017) Divakarla, U.; Chandrasekaran, K.Trust is a significant facet in decision making of any distributed network. Cloud computing is a new computing model that provides computing resources to consumers. Due to outsourcing. there is always an uncertainty about the reliability and quality of the services. Though service providers assure of quality and secure services, these assurances do not satisfy the trustworthiness of the service providers for the consumers. In this paper, we have proposed a model that develops a strong trust relationship between consumer and resources of the service provider in cloud environment. This trust relation strengthens the security of the resources as well as the authentication of the consumer. The implementation proved that trust model developed is more efficient in terms of compute time and process time. © 2016 IEEE.Item Agent-based approach for the management of dynamic QoS violations in the inter-cloud environments(Springer Verlag service@springer.de, 2018) Thomas, M.V.; Chandrasekaran, K.; Mugeraya, G.Nowadays, considerable attention has been given by the researchers in the field of Cloud Computing to the emerging Inter-Cloud computing paradigm, where different cloud service providers collaborate or federate to achieve better QoS and cost efficiency. In this context, in order to prevent the unauthorized access of the distributed system components, authentication and authorization functions are to be enforced effectively. In this paper, we propose the conceptual model of the agent-based approach for the identity and access management in the dynamic inter-cloud environments where the Cloud Service Providers or the partners of the inter-cloud federation join and leave the federation dynamically. We further discuss the architectural model for the agent-based approach for solving the policy conflicts in the inter-cloud scenario while dealing with the access requests of cloud consumers in the inter-cloud environments. A few open issues in the area of identity and access management in the inter-cloud environment are also discussed. © 2018, Springer Nature Switzerland AG.Item End-to-end monitoring of cloud resources using trust(Springer Verlag, 2019) Divakarla, D.; Chandrasekaran, K.Cloud computing is the fast-growing technology in the current era. With the growth, it brings with it multiple issues like privacy, security. Trusting the service provider and his resources is the major drawback for the user. In this paper, we have proposed a trust model which builds an end-to-end trust between the service provider resources and user. Our model calculates trust based on four parameters, namely utilization, saturation, failure, and availability. Our model builds a strong trust decision which enables the user to trust the resources of the service provider. © Springer Nature Singapore Pte Ltd. 2019.
