Cloud computing as a hot topic of research and application in recent years, most IT companies and industry insiders believe that the next generation of computer network technology is the core application architecture. The emergence of cloud computing has revolutionized the traditional usage of computers. In the cloud computing environment, most application software and data is transferred to the cloud computing data center network service providers large, all applications and data management and maintenance work is delegated to the cloud computing service providers to complete. This feature of cloud computing provides users with convenience, but also brings a lot of security challenges. Controllable data storage and management will inevitably be uneasy about the user created and stored in the cloud data file, and cloud computing have a certain sense of trust in the service provider, largely restricted the development of cloud computing. Therefore, the research based on cloud computing data security has very important application and academic value. In this paper, data security in cloud computing as the research object, definition, first on the cloud computing architecture, application and research organization are discussed, including the method introduces the data security of symmetric and non-symmetric cryptography, attribute based encryption algorithm and Merkle Hash Tree related to this paper. Then, for cloud computing virtualization, large-scale, dynamic configuration and scalability and other characteristics, based on cloud computing security challenges, environment faced with security advantages and protection measures were summarized, introduces the calculation of the cloud data storage security architecture. On this basis, in the cloud computing environment for data manipulation and dynamic data validation generally lack of support of this defect, this paper proposes a verification scheme of dynamic Merkle based on Tree Hash data. In the multi-dimensional system model of centralized security protection, each dimension has focus. The user dimension to the letter for management technology as the side on point, put forward to give the trust of the ID Ze tube authorization system. Focus on the research of data encryption technology from data, design and degradation is a cloud storage security solutions. Business dimension to security juice and monitoring as a focus put forward call service cloud security monitoring system. Basic dimensions focus on network and application system host security. In addition, aiming at the problem of information security standards and put forward the cloud security standards combined with the evaluation system to improve the protection system and the implementation of multidimensional cloud. In addition, in view of the problems of data file access control in cloud computing environment, this paper proposes an access control scheme based on attribute encryption algorithm in cloud computing environment. The main idea of security solutions and the definition of the scheme assume that the participants, in detail, a series of design scheme including initialization, file access and change the access rights, the specific implementation process, and finally analyzed.
