| Cloud computing because of its characteristic of the large capacity storage capacity,distributed computing,resource sharing,and many other advantages and become the mainstream of current and future calculation mode,more and more enterprises and individuals choose to data stored in the cloud,to facilitate data management and the efficient use.With the rapid popularization of mobile intelligent terminals,mobile cloud storage as a way of service of cloud computing,has been widely used.Mobile cloud storage well solved the mobile terminal in the storage capacity limits,to prevent the risk of mobile terminal user data is lost.However,open unconstrained data upload,tend to be illegal users to intercept and temper with the threat,the user’s data what is stored in the cloud server may be cloud service provider or third party hackers illegally obtained using,resulting in the leakage of user data.Therefore,how to protect the confidentiality of the mobile cloud storage data,to provide a safe legal storage environment is one of the important issues we must pay attention to and study.At the same time,due to the mobile terminal in computing power,storage capacity,the limitation of bandwidth and battery capacity,etc,make the user cannot implement complex in the mobile cloud service environment of encryption algorithm and access control.The goal of this paper is to design and implement a set of data security in mobile cloud storage environment protection solution.In this paper,the main research work includes:1.Research efficiently realize the cloud data storage and transport safety.In this paper,a combination of digital envelopes technology to improve the properties of the encryption cipher strategy mechanism(CP-ABE)cloud storage security model.The model without affecting the cloud service performance under the premise of protecting the user’s sensitive data,realize the encryption strategies according to different properties,at the same time of improving the efficiency of access control to ensure data integrity and confidentiality in the transmission process.2.Study how to improve the efficiency and safety requirements of the mobile terminal data updated frequently.For mobile terminal frequently updated data of low efficiency,high security is not problem,put forward a kind of storage segmentation based on the technology of encryption and coding techniques.The scheme uses encryption and coding technology of the mobile terminal data update frequently,good solve the problem that the mobile terminal resource constraints,and effectively improve the security of data.3.Simulation in this paper,two kinds of mobile cloud storage security protection scheme,and the experimental data were analyzed.Experimental results show that the proposed protection scheme can significantly improve the efficiency of the update data and resource utilization of mobile terminals,at the same time effectively improved the mobile cloud storage data confidentiality and integrity,has greatly improved the security of the mobile cloud storage data. |
