A Secure Collaborative Work Scheme on the Basis of the Third Party Credible Cloud

With a variety of private cloud or public cloud universal applications, security issues of cloud computing have become a hot spot. On the basis of other scholars research of cloud security, this paper discusses major security risks in free cloud computing environments nowadays, constructs a secure collaborative work scheme on the basis of the third party credible cloud, and analyzes its detailed structure and principles. The third credible cloud includes three main modules: authentication, key distribution and data transmission, and monitoring management. The scheme conduces to a variety of cloud entities security and is of high feasibility.
