Abstract

The invention discloses a cloud encryption storage method for an intelligent terminal. The method comprises the following steps: performing identity authentication on a user; after the authentication, if a backup instruction sent by the user is received, determining backup data selected by the user according to the backup instruction, and encrypting the backup data according to a key prestored in the intelligent terminal to obtain encrypted data; sending the encrypted data to a cloud server; if a restoring instruction sent by the user is received, receiving the encrypted data sent by the cloud server and decrypting the received encrypted data sent by the cloud server according to the key restored in the intelligent terminal. According to the invention, the condition that the key is stolen in a transmitting process is avoided, the risk that the backup data of the user is illegally stolen is reduced and the confidentiality is improved. The invention further discloses the intelligent terminal, including a security chip for encrypting and decrypting the backup data, wherein a key is presorted in the security chip. The intelligent terminal also has the above advantages, which are not repeated here.

Description

technical field [0001] The invention relates to the technical field of cloud storage, in particular to a cloud encrypted storage method for an intelligent terminal. The invention also relates to an intelligent terminal. Background technique [0002] In order to avoid the loss of file data (video, audio, pictures, address book, text messages, documents, etc.) in the smart terminal, sometimes it is necessary to back up some data and send it to the cloud for storage. The current upload process is: file classification - cloud server identity authentication - file encryption - file compression - data encapsulation - upload; the download process is: cloud server identity authentication - comparison with mobile phone files - resume download - decompression - decryption. In this process, the key used for encrypting and decrypting files is stored on the cloud server, and needs to be obtained from the cloud server after the authentication is passed. [0003] However, if the key is s...
