A ciphertext cloud storage method and system
The present invention relates to a ciphertext cloud storage method and system. In a system composed of at least one client and a cloud server, the storage method is as follows: 1) The user chooses to use ciphertext and / or plaintext for data synchronization in the data stored at the client , and select an encryption algorithm for the ciphertext; 2) Use the authentication parameters provided by the user to generate the master key, and use the two-level key of the master key + encryption and decryption key on the client to encrypt the data synchronized with the ciphertext and Back up the master key; 3) Synchronize the ciphertext and ciphertext index between the client and the cloud; or establish a plaintext index on the cloud after synchronizing the plaintext synchronization data between the cloud and the client; 4) Store the plaintext and / or ciphertext On the local private cloud storage server or according to the mount point requested by the user, it is stored on the cloud storage provider's storage server. In the present invention, data will not be lost if the terminal is lost, and only the cipher text form of the file will be lost if the protection is improper, and the storage system can be connected to multiple cloud service providers at the same time.
