Research And Implementation Of The Security Scheme On Mobile Cloud Storage System

With the development of mobile Internet technology and widely use of smart mobile phones, the amount of data stored in smart mobile terminals is increasingly large, so there is great demand for new technical methods to solve large data storage security problem faced by mobile terminal. As a cooperative product of cloud storage and smart mobile terminals, mobile storage can not only break storage capacity restrictions in mobile terminals, but also solve data backup problem perfectly. Users can manage data backups and can recover data with mobile network at any time anywhere, reducing the risk of data lost caused by mobile terminal malfunction. Currently there are dozens of mobile cloud storage applications in Internet market.However, the security of mobile cloud storage may be threatened from mobile terminals and cloud storage servers. Unsecure cloud storage service providers may reveal users’ secret information under active or positive circumstance, so the security of mobile cloud storage service remains to be raised to a higher level. The aim of the thesis is to design and implement a security protection solution in mobile cloud storage environment. The solution can back up users’ data in cloud storage servers safely and reduce the possibility of data lost and irrecoverableness. The solution guarantees data security in cloud storage servers and prevents data reveal from the servers. The solution also provides safe data share methods which can guarantee data confidentiality.The main works of the thesis are listed as follows.1. Researching mobile cloud storage technology, and analyzing the security threats in mobile cloud storage environment. The mobile cloud storage system includes mobile terminals and cloud storage servers and we analyze possible security threats from the two aspects. We also research the security technology which can be used to solve these security problems, making theory preparation to design the mobile cloud storage security protection solution.2. Designing the mobile cloud storage security protection solution and solving the problems of data lost and revelation in mobile cloud storage environment. The thesis’s solution mainly focuses on personal users or loose-organized and small group. The solution emphasizes on three aspects:identity authentication, data security backup storage and data share. In order to archive these functions, five key processes are designed, including user identity authentication, data encryption and upload, data decryption and download, authorizing access and revoking authorization.3. Simulating the mobile cloud storage security protection solution. The thesis chooses Android as the mobile terminals’ platform and Hadoop open-source frame as cloud storage frame, using HDFS to provide the function of data cloud storage.
