Embodiment Construction

[0030] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0031] First of all, in order to facilitate the understanding of the present invention, the technical terms involved in this solution are firstly defined and explained.

[0032] Object storage: An object is the basic unit of object storage device (OSD) processing, and is distinguished by a unique ID identifier. Each object is a collection of ordered bytes, including data and attributes. The objects in OSD are divided into root object (RootObject), partition object (Partition Object), collection object (Collection Object) and user object (UserObject). Among them, the root object corresponds to the...

Abstract

The invention discloses a cloud storage data downloading method based on data self-destruction. The method comprises the following steps: S1, establishing connection with a data storage system server;S2, downloading ciphertext data by using an interface of a data storage system and extracting key meta-information of the head of the ciphertext data; S3, establishing connection with each storage node according to the key meta-information, writing the ciphertext data into a target file if any connection fails, marking the ciphertext data unsuccessfully, and ending the downloading process; If allconnections are successful, turning to S4; S4, reading each key equal part, and storing the key equal parts in a specified array; S5, recombining the keys from the specified array; And S6, decryptingthe ciphertext by using the secret key, and writing the decrypted data into the target file to finish downloading.

Description

technical field [0001] The invention belongs to the technical field of computer data storage, and in particular relates to a cloud storage data download method based on data self-destruction. Background technique [0002] Traditional data destruction technologies include the following types according to different forms of operation methods: data deletion based on the file system, data overwriting and physical level destruction. Among them, the data deletion based on the file system is divided into file deletion and device formatting according to different operation granularities. File deletion is the most direct way to delete data. It uses the methods provided by the file system to explicitly delete files or data. In mainstream file systems, file deletion only deletes the corresponding index of the file, and does not correspond to the file data. Delete the disk sectors; device formatting is to use the formatting tool provided by the file system or a third-party disk managem...
