This paper analyzes the security problems existing in the Hadoop architecture and file sharing system, and puts forward the corresponding solutions with the attribute encryption algorithm. First of all, for the security problem of Hadoop architecture in cloud computing environment, this paper designs a complete set of solutions to solve the security problem with Cce-abe algorithm, and introduces the main idea, security hypothesis and the whole process of the security Hadoop architecture. Finally, by using the K service to classify the data, this paper illustrates the application of the secure Hadoop architecture. In addition, aiming at the security problem of file-sharing system in cloud computing environment, this paper proposes a set of schemes based on Em-abe algorithm, introduces the basic algorithms to be used in attribute addition and attribute revocation in the system, and describes the main ideas, security assumptions and a series of operations in the file system in detail ( Including initialization process, new file creation, data file deletion and access rights change process, etc., and at the end of this program security analysis.
