Distributed Cloud Storage Encryption System Design And Implementation

With the rapid development of information technology, more and more data information, cloud computing is widely used by people and recognition. At this point, extend from the cloud base of cloud storage technology is becoming more and more popular.At present, the cloud storage technology in cloud data security, there are many challenges, such as a privileged user access, privileged users that refers to the internal staff, cloud service providers, or have access to the user account of illegal users; Cloud service providers to ensure availability of data, usually the user data backup, this may lead to sensitive information can be retrieved, cannot be completely deleted. Illegal interception of data during the data transmission and so on.In order to allow users to experience relatively more secure storage, the subject to decentralized encrypted cloud storage concept as the core design of a distributed fast encryption system based on cloud storage security for the user to do some protection. To split the file system, encryption, directory information record, upload,download and many other functions, and provide users with a convenient setting area. Finally, by connecting local data, relevant content storage system for recording user preset information.Users use the system, it can be sensitive information encrypted and are stored in different cloud server, individual managers to avoid illegal access to information,and also to prevent the data be recovered and be intercepted. Due to the scatter data stored in the cloud, but also avoid the whole data set to a resulting in the risk of cracking. In addition, files before using fast encryption algorithm for storage, so as to improve the performance of the system.
