Abstract

The invention provides a data storage method, a data security apparatus and a data storage system. The data storage method comprises: obtaining first startup information of private cloud bound with the private cloud, a user key and a protective key of the user key, encrypting the user key by utilizing the protective key, and storing the first startup information, the protective key and the encrypted user key; receiving a storage instruction, wherein the storage instruction carries target data and second startup information of the private cloud bound with the private cloud; generating an authorization instruction carrying the second startup information, wherein the authorization instruction is used for indicating operation of decrypting the user key by utilizing the protective key; and when the second startup information is the same as the first startup information, decrypting the user key by utilizing the protective key according to the authorization instruction, encrypting target data through the user key, and sending the decrypted target data to public cloud to perform storage. Through the technical scheme provided by the invention, the security of the target data can be improved.

Description

technical field [0001] The invention relates to the technical field of network security, in particular to a data storage method, a security device, and a data storage system. Background technique [0002] The rise of cloud storage provides a better solution for users' ever-increasing storage needs, and hybrid cloud is the main model and development direction of cloud computing. [0003] Hybrid cloud combines the characteristics of public cloud and private cloud. Users can complete the corresponding data processing business in the private cloud, and send the target data from the private cloud to the public cloud for storage; in order to improve data security, cloud services are usually used The data security protection measures provided by the provider, that is, the user sets the corresponding user password in the private cloud to generate the user secret key, uses the generated user secret key to encrypt the target data, and encrypts the encrypted target data and the generat...
