Abstract

The invention relates to a data anti-leakage protection method for a cloud storage environment. The method comprises the following steps of setting system symbols and parameters; performing system initialization; sending a user attribute list L to an authorization mechanism TA and requesting generation of an attribute secret key by a user; after the authorization mechanism TA receives the user attribute list L, generating a private key SKL of the user; performing data encryption; performing keyword encryption; generating a trap door; performing server search; and performing data decryption. Compared with the prior art, the method can directly search encrypted information stored in a cloud storage server effectively in a non-trusted environment, ensures safety of data and privacy of the user, and can support search access control of different user fine grits. The method provides reliable guaranteed for data safety in the cloud storage environment and has a good application prospect.

Description

Technical field: [0001] The invention belongs to the field of information security, in particular to a data leakage protection method for a cloud storage environment. Background technique [0002] In recent years, cloud storage technology has been rapidly developed and widely used due to its advantages of low cost and good scalability. In 2013-2014, many data leakage cases occurred in the cloud storage environment, such as the Prism Gate incident, the South Korean credit card information leakage incident, the 12306 user information leakage incident, the Chinese social security data leakage incident, and the reselling of user information by multiple banks. The information security problem in the cloud storage environment, especially the data leakage prevention problem in the cloud storage environment, has aroused great concern and attention from the society. [0003] As we all know, data encryption and access control are the most effective methods for data leakage prevention...
