Abstract

The invention discloses a file encryption and decryption method based on cloud storage. The file encryption and decryption method comprises the following steps of starting file write to a cloud storage platform by an application terminal, and conducting fragmentation storing on a file by the cloud storage platform; conducting distributed encryption on the file which is stored in the cloud storage platform in a fragmentation mode by an encryption and decryption platform; conducting distributed decryption on the file which is stored in the cloud storage platform in the fragmentation mode by the encryption and decryption platform. The invention further provides a file encryption and decryption system based on the cloud storage. According to the technical scheme, repeated file fragmentation and aggregation processes are reduced, waste of computing capability is avoided, and meanwhile the processing speed of encryption and decryption is improved.

Description

technical field [0001] Embodiments of the present invention relate to file processing technologies in the field of computer networks, and in particular to a method and system for encrypting and decrypting files based on cloud storage. Background technique [0002] With the needs of scientific research, business, diplomacy and military, there are more and more demands for encrypting plaintext files and decrypting ciphertext files, and the encryption algorithms and decryption algorithms used are becoming more and more complex. The encryption keys and Decryption keys are also getting longer, resulting in longer and longer computation times for encryption and decryption. In addition, in the cloud computing environment, files are stored in multiple cloud storage servers in fragments. If the information on a certain cloud storage server falls into the hands of the enemy, it may cause partial confidentiality of the files. Therefore, it is also necessary to implement distributed en...
