A Hybrid Security Model for Distributed Cloud Management

Cloud system is gaining the importance in public environment. But security is always a critical challenge while sharing the valuable information. In this work, a high level integrated security model is presented for managing large data on cloud system. In this work, a RSA integrated SHA method is presented to provide the secure file management in distributed cloud. The proposed authentication and cryptographic model has provided the security for public and private cloud system. The work ensures the communication level, user level and file level security. The efficiency results show that the model has improved the security and the reliability in the system.
