Abstract


With the explosive growth of information and applications demand continues to improve, people 's capacity and throughput storage systems have higher requirements . Can be a large number of inexpensive, small storage capacity of existing storage systems are organized into a large -capacity , high-throughput storage systems , distributed file systems in a variety of applications, rapid promotion. Most existing distributed file system is stored in plain text mode , there is no authentication. Although such a distributed file system can be integrated storage space, but in the case of multi-user can not ensure the user's private information security . Centralized security management of distributed file system is open source distributed file system GlusterFS existing two-party framework , based on the introduction of an independent third-party modules centralized security management server for all original client sent to the storage node various file operations for permission to examine and certificate management , etc., and recording system operation log . Distributed File System so as to increase the user authentication, access control , encryption, storage , and audit functions. Centralized security management server is a distributed file system architecture of this new core . Centralized security management server through the use of multi-threaded architecture to improve concurrency service capabilities, through user identification in the system user authentication, authorization through well-designed database can be carried on the user's operating authority review , file groups can be achieved through the security file sex sharing, through the issuance of a certificate authority and recovery , you can prevent a malicious user to falsification of identity theft or identity theft data behavior. For centralized security management server design integrated test results show that the centralized security management server using the five key technology can effectively prevent unauthorized access to users in the system , access to identity theft and other malicious acts . Performance tests show that the introduction of centralized security management mechanism for the entire distributed file system throughput is not much affected.
