The Research Of Cloud Data Security Synchronization Based On SyncML Protocol

In the mobile internet era,the number of mobile terminal equipment that people own is constantly increasing, with the mobile network data is increasing at the same time. There is an urgent need for secure synchronization of data between many of their mobile devices.The SyncML protocol has been adopted to solve data synchronization problems between mobile devices. the development of cloud computing industry has brought us great convenience. In this paper, the problem of data security synchronization for mobile devices in cloud computing environment is studied.In this paper, the related technologies of cloud data security synchronization were studied;the security synchronization model based on SyncML protocol was proposed for cloud data;the security synchronization system based on SyncML protocol was designed and implemented for cloud data;the system was evaluated comprehensively.The experiment proved the feasibility of the synchronization model based on SyncML protocol.The main contents of this paper are as follows.(1) The techniques related to the secure synchronization of cloud data were studied,including the SyncML data synchronization protocol and the image fingerprint extraction algorithm based on SHA-1,which make it could extract the fingerprint of the image quickly on the Android system.(2) A security synchronization model based on SyncML protocol was designed for cloud data in this paper. The model contains of two parts that were the synchronization model of structured cloud data based on SyncML protocol which was effective for the data types of contacts and short messages and the synchronization model of cloud data of image based on the SyncML protocol which was used for image.The two models were introduced in detail by the timing diagram and flow chart.(3) The cloud data security synchronization system based on SyncML protocol was designed and implemented.The system's mobile device side was developmentted based on the Android,server-side was developmentted based on the Windows operating systemt.(4) The evaluation of the cloud data security synchronization system based on SyncML protocol was completed.A large of experiments indicated the feasibility of the cloud data security synchronization model based on SyncML protocol, the perfect function and the good performance of the cloud data security synchronization system.
