The invention provides a kind of cloud encryption storage method of intelligent terminal, shown in Figure 1, Fig. 1 provides for the present invention
A kind of intelligent terminal cloud encrypt storage method process flow chart；The method includes:
Step s101: authentication operation is carried out to user；After the completion of certification, if receiving the backup instruction of user's transmission
Then enter step s102；If receiving the recovery instruction of user's transmission, enter step s103；
Step s102: the Backup Data that user selectes is determined according to backup instruction, according to prestore in intelligent terminal
Key is encrypted to Backup Data, obtains ciphertext data；By ciphertext data is activation to cloud server；
Step s103: receive the ciphertext data that cloud server sends, according to the key pair prestoring in intelligent terminal
The ciphertext data that the cloud server receiving sends is decrypted.
Wherein, user is carried out with the process of authentication operation particularly as follows:
Collection the identity information of identifying user, carry out identity information certification according to identity information；
The cloud service account information that receive user sends；
Cloud service account information is sent and carries out account information certification to cloud server.
Preferably, the acquisition process of the key prestoring in intelligent terminal particularly as follows:
After receiving the cloud service account information of user's transmission first, generate key according to cloud service account information, and
By in key storage to intelligent terminal.
It is understood that the cloud service account of different users is different, the cloud service account of each User logs in oneself
Carry out the encrypted transmission of Backup Data afterwards, in order to avoid obscuring occurs in the Backup Data between different user, therefore be encrypted solution
Key when close should be corresponded with cloud service account, therefore can generate key according to cloud service account information.Certainly, may also be employed
Other AESs generate key, but will ensure that generating key is corresponded with cloud service account.
And, after user newly changes intelligent terminal due to some reasons (for example original intelligent terminal's damage etc.), this intelligence
Do not store the corresponding key of cloud service account in terminal, can make the ciphertext data in cloud server cannot be extensive in this case
Multiple to intelligent terminal, so when need to regenerate the corresponding key of cloud service account and store to the intelligent terminal newly changing.
Simultaneously it should be noted that because key is corresponding with cloud service account, for avoiding disabled user to steal cloud service
Corresponding cipher key content is learnt, generating, according to cloud service account, the key schedule being adopted during key needs to protect after account
Close, can not be known algorithm, in different intelligent terminal, the key schedule of setting can be the same or different, when
So, the present invention does not limit the particular content of key schedule.
Specifically, identity information is biological attribute data.Here biological attribute data is specially vocal print, fingerprint, voice
Any one in password.It is understood that if being authenticated using pin mode, user needs to remember the close of oneself setting
Digital content, is so easy to situation about forgetting Password occurs, therefore if adopting the data such as vocal print, fingerprint, voice, then can be big
Reduce greatly situation about forgetting Password, reliability is high.Certainly, these are only several preferred versions, other kinds of life may also be employed
Thing characteristic.
The invention provides a kind of cloud encryption storage method of intelligent terminal, after authentication, to Backup Data
It is encrypted using the key being pre-stored within intelligent terminal during deciphering, close without obtaining from cloud server
Key.It can be seen that, key storage in intelligent terminal, and is not stored in cloud server, during encrypting and decrypting by the present invention
Key do not need the localized transmissions beyond intelligent terminal, it is to avoid in transmitting procedure, the stolen situation of key occurs, and significantly subtracts
The risk that the Backup Data of little user is illegally stolen, strong security.
Present invention also offers a kind of intelligent terminal, shown in Figure 2, a kind of intelligent terminal that Fig. 2 provides for the present invention
