Abstract: In a file sharing system, a key manager unit realizes a correspondence between the first user identifier and the first public key in response to a registration request of the first user, generates a first key material for encrypting the first file into a first encrypted file, and generates a first credential according to the first user identifier, the first file identifier, the first public key and the first key material after receiving an access-right claim request to the first file from the first user. A file storage unit stores the first encrypted file and the first credential. The first user uses the first user identifier, the first file identifier and the first private key to retrieve the first key material out of the first credential, and uses the first key material to decrypt the first encrypted file into the first file.

Abstract: A method for deploying a computer operating environment and a deployment system are provided. A template machine is provided. A deployment program is executed in the template machine for scanning data of an operating system and applications in the template machine. The data are segmented into multiple segments and then encoded. An index and a checksum for each of the segments called metainfo are created. The metainfo is distributed to terminal machines within a network domain. After receiving the metainfo, every terminal machine obtains the segments, decodes the segments, and verifies the correctness of the received segments with the checksum. When requested by other terminal machines, the terminal machine reads the specific segments and then distributes those to the other terminal machines via a peer-to-peer data sharing protocol. The deployment is completed after all of the segments of operating environment are written in the terminal machine.
