Research and Development of Data Security Multidimensional Protection System in Cloud Computing Environment

In the cloud computing environment, most application software and data are transferred to the cloud computing data center, network service provider, all applications and data management and maintenance work are entrusted to the cloud computing service providers to complete. The feature of cloud computing provides convenience for users and brings many security challenges. In this paper, firstly, the architecture of cloud computing applications were discussed and studied in the organization and, for virtualization, cloud computing, large-scale, dynamic and extensible, based on cloud computing security challenges, summarizes the advantages and safety and environmental protection measures, on the basis of in this paper, we propose a dynamic hash authentication scheme based on Merkle tree. With the user dimension as the letter and the management technology as the side, the trust of empowerment management system is put forward. Focus on data encryption technology, from data, design and demotion are cloud storage security solutions. In addition, in view of the problems existing in the information security standard, we put forward the combination of the cloud security standard and the evaluation system, and improve the multi-dimensional cloud protection system and implementation.
