Abstract

The invention discloses a user-controllable data retravel method and a data storage method, terminal and system. The data storage method comprises the steps that an index file is created for data to be stored; according to an encryption strategy preset with an authentication server, a first secret key is obtained from the authentication server, and symmetrical encryption is conducted on the index file through the first secret key to obtain an encrypted index; symmetrical encryption is conducted on data to be stored according to a second secret key provided by a user to obtain encrypted data; a corresponding access structure is created for the data to be stored according to the preset user access strategy, and a CP-ABE algorithm is adopted to encrypt the second secret key through the access structure so as to obtain an encrypted secret key; the encrypted data, the encrypted index and the encrypted secret key serve as ciphertext data to be uploaded to a system server, and the system server uploads the data to a cloud storage server after completing integrity checking of ciphertext data through the authentication server. The efficient and safe sharing in a cloud storage environment is achieved by adopting the embodiment.

Description

technical field [0001] The present invention relates to the technical field of computer networks, in particular to a user-controllable data retrieval method based on a cloud storage environment, a user-controllable data storage method, a terminal and a system. Background technique [0002] In an open network environment, people store and share more and more data through the network in their study, work and life. As a new network application model, cloud storage service uses cluster applications, grid technology and distributed File system and other functions, a large number of different types of storage devices in the network are combined to work together through application software, and jointly provide data storage and business access services to the outside world. Users can store their data remotely in the cloud storage center and access it on demand, which is convenient for users to access, saves expenses for enterprises, and improves availability and reliability. Howev...
