Research Of Cloud Storage Security Technology

Cloud computing is a developing computational model. Cloud computing centerprovides users with various types of services through network access. Cloud storage is a basicservice. With cloud storage service, the user is able to drop the local storage device and accesshis own data whenever and wherever possible. Cloud storage is still in the infant stage ofdevelopment, the research on its security at the initial stage.Firstly, this paper focuses on the current research of cloud storage security. The technicalaspects of the security concern are confidentiality, integrity, availability, monitoring and audit.In this paper, current research on cloud storage security is summarized and introducedaccording to the5security properties above.Then, this paper introduces a file-share method to solve the data storage and sharingproblem. The method focuses on the confidentiality, integrity and key distribution problem.Finally, in view of the untrusted cloud computing execution environment, a cloudsecurity encryption service method is introduced. In such a process, the key is merged into thealgorithm itself, never showed up in the cloud execution environment. Also, this methodprovides an asymmetric cipher implementation.
