Network data storage method and server

Abstract

The invention discloses a network data storage method and a server. The disturbing network data storage method provided by the invention comprises the following steps: judging whether a data file needs to be encrypted and/or signed or not by the server according to configuration information of the storage region of the data file; encrypting a network data stream uploaded at a client when the data file needs to be encrypted but does not need to be signed according to the judgment, and writing the encrypted data stream into the data file; writing the network data stream uploaded at the client into the data file when the data file needs to be signed but does not need to be encrypted according to the judgment, and signing the data file; and encrypting the network data stream uploaded at the client when the data file needs to be encrypted and signed according to the judgment, writing the encrypted network data stream into the data file, and signing the data file. The invention improves the openness, the expansibility, the robustness and the reading/writing visit efficiency of the network storage server on the premise of ensuring the confidentiality and the completeness of the data storage.

Description

technical field [0001] The invention relates to the field of network security, in particular to a network data storage method and server. Background technique [0002] With the development of TCP / IP network technology, File Transfer Protocol (File Transfer Protocol, FTP) and World Wide Web Distributed Authoring and Versioning (Web-based Distributed Authoring and Versioning, WEBDAV) protocols have been more and more widely used. Use FTP and WEBDAV protocols to provide network storage for clients, forming a network storage that supports standard protocols. Users can use clients that support FTP or WEBDAV to perform server-side file read access (download network data) and write access (upload) through the network. Network data) and other operations. [0003] In order to implement network storage supporting FTP and WEBDAV protocols, corresponding server systems (FTP server and WEBDAV server) are often installed and deployed on the server side. Most of the existing FTP servers a...

AI Technical Summary

Problems solved by technology

[0005] 1. The secure file system is generally a private system without a unified interface and lack of openness;

[0006] 2. The encryption algorithm of the entire secure file system is fixed and unified, and the scalability is insufficient;

[0007] 3. Since all files in the secure file system are encapsulated in a single file in the underlying file system, when reading and accessing a specific file in the secure file system, it is necessary to extract the file from the single file in the underlying file system ; When writing access to a specific file in the secure file system, the file needs to be written to a single file in the underlying file system, and the read / write access efficiency is low

[0008] 4. The encryption algorithm of the secure file system is relatively fixed, and the secure file system centrally manages the internal file information and keys. If the area (disk sector) storing file information or key parts is damaged, the entire secure file system will be damaged. Inaccessible, insufficient system robustness
