Abstract

The invention provides a cloud data access method, device and equipment, and a computer readable storage medium. The method comprises the following steps of acquiring data to be uploaded and the levelinformation of a user side encryption and decryption device; sending the data amount of the data to be uploaded and the level information of the user side encryption and decryption device to a network side management device; receiving a quantum session key sent by the network side management device; encrypting the data to be uploaded according to the quantum session key and an encryption algorithm; and sending the encrypted data to be uploaded to a user terminal and uploading to a cloud storage device. Through using the anti-quantum-attack characteristic of a quantum key, cloud storage data can be prevented from being obtained through a brute force attack, collision, and the like. The safety of cloud storage data is effectively protected and information leakage is prevented. A more safe encryption service can be provided for a high-priority user and sensitive data to meet the personalized need of the user.

Description

technical field [0001] Embodiments of the present invention relate to the field of encryption technology, and in particular, to a method, device, device, and computer-readable storage medium for cloud data access. Background technique [0002] At present, information security is becoming more and more serious. Various mobile phone and computer viruses, worms, etc. have great insecurity for the information stored on mobile phones and computers by users. With the emergence of cloud services, various cloud disk services are open to users free of charge. The security protection measures of the cloud will be much higher than the security protection level of the user's computer or mobile phone. However, due to the user's personal privacy of information stored in the cloud Due to concerns, users are not too accepting of cloud storage of information or cloud backup of information. [0003] In order to enable users to actively store or back up information in the cloud, in the prior ...
