Research and implementation of cloud computing security technology based on HDFs
Guangdong University of Technology Guo San Chang
The innovation of this paper is as follows: (1) based on the principle of Ibe algorithm, the security mechanism of identity authentication under HDFS datanode to client access is designed to make up for the defect that the client access Datanode has not been authenticated under the original HDFs architecture, So that malicious or phishing users can not go through the namenode of the main server to steal private data on Datanode to ensure data security. At the same time, using the principle of class Ibe algorithm, the third party trusted organization is discarded, the private key is generated by client, which reduces the complexity of key management caused by key generation, distribution and storage, and simplifies key management. (2) Design and implement the security scheme of data transmission and storage based on HDFs cloud computing file management system, using symmetric encryption Algorithm DES, AES, 3DES and so on client to encrypt the file block data to ensure that the client to cloud computing file management system transmission and storage data security. It verifies the integrity of data in a transport or stored procedure by processing a digest of the transmitted data. (3) The design and implementation of the log management of user behavior monitoring and access control scheme to control user access rights. Log management facilitates system management and maintenance of data, prevents data loss, and monitors user behavior; Access control mainly controls the private and shared file data, the files in the shared list are common, the others are private, and only the file owner is visible.
