A model of cloud data secure storage based on HDFS

As more and more organizations and individuals tend to outsource their data to cloud storage, the security and user privacy protection attract more attention. Previous work mostly focused on the user identity authentication to keep the security, while in this paper, a novel model of cloud secure storage is proposed, which combines the Hadoop distributed file system(HDFS) with symmetric and public-key cryptography. The model uses the HDFS as the storage platform and the XML format as the logical storage structure. This model can not only solve the problem of storing massive data, but also provide data access control mechanisms and ensure sharing data files with confidentiality and integrity among users in cloud environment.
