Research And Implementation Of Encrypted Cloud Disk Technology

The advent of the information age makes the personal data show an explosive growth.The method of increasing the volume of storage by increasing the number of hard disk is difficult to meet the needs of people.Because of the advantages of low cost,convenient access and large capacity,the cloud storage has become the new favorite of users.However,an endless stream of security incidents makes people worry about storing data in the cloud,which greatly limits the popularity and development of cloud storage.Therefore,the research of data security in cloud storage is of great significance for the development and popularization of cloud storage.In view of the security problem under the cloud storage environment,this paper proposes an encrypted cloud disk with security attributes.Users can transmit the data into the cloud disk.Then the cloud disk will encrypt the data and then send the data ciphertext to the cloud storage server to save it.In this paper,the encrypted cloud disk is studied and implemented.The hardware part is based on ARM926 processor to build the overall framework.The software part completes the programming of the encryption and decryption module,the cloud management module and the file management module.In addition,the encrypted cloud disk has been partially optimized to improve the efficiency of the disk.The encrypted cloud disk isolates the key from the PC in a portable hardware client mode.Users can regain full control of data by way of keeping the key so that even if the ciphertext is stolen,the information can not be cracked.The double guarantee of the ciphertext storage and the controllable key ensures the data security.The test of the encrypted cloud disk shows that it has basically reached the target requirements,and the security and transmission rate are both ideal.Through the study of the encrypted cloud disk,we can put forward new protection ideas for the data security in cloud storage field.In particular,the idea of mobile safety protection is of positive reference to the current market situation of mobile devices that dominate the mainstream.
