Research on key technologies for big data cloud storage system
Therefore,the key technologies of a big data cloud storage system are introduced,and the distributed cloud storage technology is analyzed according to the rules of the directional random walk. In order to guarantee the data security,the data is encrypted with the RAS encryption algorithm,the public key or secret key is used to encrypt the data which needs to be stored, and another corresponding decryption key is adopted to decrypt the data. In order to guarantee the reliability of the system and data access efficiency,data retrieval technology is analyzed in detail. The efficient integration and network storage resource management are reached by means of the combination of cloud storage technology,data encryption technology and data retrieval technology,which provides a friendly connection window for outward to make the release of the cloud computing network data quicker,and provide users with convenient storage service. The simulation experiment results show that the cloud storage system with the proposed key technology has shorter running time,lower overall energy consumption and higher availability.
