Abstract

The invention discloses a file data processing method and device. The method is applied to a cloud file storage system, each file storage system adopts different encryption modes, and the method comprises the steps of acquiring a write-in request, wherein information carried in the write-in request comprises a user identifier and a file system identifier of a to-be-accessed file storage system; determining encrypted information to be used based on the user identifier and the file system identifier; encrypting the currently written user data by adopting the encrypted information to obtain encrypted data; and storing the encrypted data to a target position corresponding to the write-in request. According to the file data processing method and device, the technical problem that in an existing file data processing mode, the processing efficiency and safety are low when file data are encrypted is solved.

Description

technical field [0001] The present application relates to the field of computer technology, in particular, to a file data processing method and device. Background technique [0002] Based on the consideration of data storage security, the file storage system on the cloud server can separate key management and use. First, a third-party key management system such as KMS can be introduced in key management to ensure security. The file storage itself Only the ciphertext key is saved; secondly, when encrypting the file content, multiple encryption schemes can be used: one is the overall encryption method, and the traditional file encryption is mostly realized by the overall file encryption method. Although this encryption method is simple to implement, However, every time a file is read or written, the entire file content needs to be encrypted and decrypted, so it is only suitable for small files (for example, documents, pictures, etc.) ) processing efficiency is very poor; the ...
