Security and trust life cycle of multi-domain cloud environment

Cloud computing allows users in sharing services and resources over the internet. For a single cloud, resource and service sharing capabilities are limited, while several applications frequently require various cloud centers over the Internet to jointly deliver services. The concept of the inter-cloud environment will integrate services across multiple independent clouds. However, building a secure and trustworthy inter-cloud environment to achieve the association goals is a critical problem. On the other hand, current cloud security mechanisms are too stiff, and they require the capability to establish reliability ensured by the service provider. This paper describes the different aspects associated with security and trust life cycle of multi-domain cloud in the context of the inter-cloud environment.
