Abstract
In recent years, many countries, companies, and research groups have launched their own cloud systems. Due to security issues, there is a limitation for a single-provider of a cloud to cooperate with other cloud systems to maximize the function of available resources. In addition, each cloud computing system provides a digital identity for a user. Hence, a user has many digital identities for difference clouds. Therefore, in hybrid cloud the user has many digital identities. The broadcast media market is discovering the business advantages in using a cloud system in its communication. In cloud computing environments, we propose federated layered broadcast cloud security architecture guarantee efficiency and secure authenticated of multiple broadcasters. However, each broadcaster can be dynamically broadcast messages into an authorized group of receivers. A secure mutual authentication protocol for federated broadcast cloud (MAFBC) is presented. In this paper, we combine a federated identity management mechanism and a forward secure broadcast encryption scheme using HIBE to have a unique digital identity for a user, which will handle all the above problems. Moreover, the key distribution and the mutual authentication problems will be handled.
