A Trust, Privacy and Security Infrastructure for the Inter-Cloud

Cloud Computing is one of the most important security challenges to manage and assure a secure usage over multi-provider Inter-Cloud environments [1] with dedicated communication infrastructures, security mechanisms, processes and policies. Based on the collection of various Inter-Cloud usecases and scenarios within the private and public sector like DMTF (Distributed Management Task Force), NIST (National Institute of Standards and Technology), GICTF (Global Inter- Cloud Technology Forum) and ENISA (European Network and Information Security Agency) we analyzed and summarized the range of requirements are trust and reputation management, sticky polices with fine grained access control, privacy preserving delegation of authority, federated identity and security management. The cloud service providers are then able to offer a reliable privacy preserving Infrastructure-as-a-Service to their clients
