Together.
According to the invention have the characteristics that technique scheme obtains:
One, safe cloud storage is achieved
The present invention reinforces from content:
1, the content being stored in cloud security storage and sharing service platform is encryption, even the manager of system exists
Also content therein cannot be checked in the case of without permission；
2, user can only see and open the file oneself stored or others licenses to the file of oneself；
3, user is encryption to the information transmission between cloud security storage and shared server；
4, license to other people the most safely, and do not worry unauthorized user it can be seen that it.
Two, safety and flexibly authorization
Present invention authorization based on Digital Envelope Technology, have employed single key cryptosystem and PKI is close in digital envelope
Code system.The authorized person of file adds first with the symmetric password encryption file randomly generated, the PKI of recycling grantee
Close symmetric cryptography, is referred to as digital envelope by the symmetric cryptography after public key encryption.Grantee is when opening file, it is necessary to first
Decipher digital envelope with the private key of oneself, obtain symmetric cryptography, symmetric cryptography could be utilized to decipher file.User utilizes system to carry
The licensing scheme of confession, can flexibly by file authorizing in platform registration any user.
Three, local use, high in the clouds stores
After file is added into cloud security storage and sharing service platform, being stored on cloud file server by safety.
When user wants to use file, only need to be from local log-on server, the most just can be as using locally stored file
Use the file leaving high in the clouds in.And be not required to be concerned about the encryption and decryption of file and upload the problem of download, cloud security storage and
Sharing service platform can be automatically performed.
