Abstract: Cloud computing is a freshly industrializing new technology for multipart systems with large-level services distribution among various users. Therefore, verifying and validating of both users and services is a important issue for the confidence and protection of the cloud computing. SSL Authentication Protocol, once implemented in cloud computing, will become so complex that users will experience high overloaded issues in both calculation and communication. The proposed research is, based on the Attribute-based hierarchical method for cloud computing and its equivalent cryptographic and signature methods, presented a new Attribute-based security protocol for cloud computing and services. Through simulation testing, it is shown that the security protocol is more significant and capable than SSL Authentication Protocol, specially the more significant on user side.
Keywords: Cloud computing, Security, Attribute, Simulation, Protocol.
