Cloud storage services bring users a convenient, cross-device and practical application. A great number of users ranging from individuals to large-scale corporates grow and hold on the almighty information to cloud storage services. However, the lack of guaranteeing data security is a mortal defect resulting in the strong mistrust of users. Therefore, we propose and implement the SecureDropbox system which constructs a secure architecture including key generation, key management, file encryption, and synchronization modules to prevent risks of data disclosure.
