Abstract
With the emergence of mass storage systems and the development of the Distributed File System, Cloud storage system has become the focus of the industry. The cloud storage services on mobile terminal have been putted on the agenda based on the rapid development of intelligent mobile terminal. Based on the analysis of the architecture of HDFS and Dynamo, a mobile Terminal Security strategy is presented in this paper. The database technology and t he dynamic consistent hashing algorithm are adopted to deal with different target groups. According to the storage costs of nodes, data would be integrated scheduling by the storage system. Make full use of the advantages of AES(Advanced Encryption Standard) and RSA. A solution that combines AES and RSA encryption algorithm is proposed to implement the mobile terminal cloud storage security. Through the theoretical analysis and the simulation results, the cloud storage strategy proposed in this paper can make the cloud system achieve load balance. Moreover, multi-copy mechanism can improve the overall efficiency of the system.
