System and method for security management of Internet archives based on attributes

The invention discloses a system and a method for security management of Internet archives based on attributes; the system comprises a data owner module, an authorization center module, an authorization mechanism module, a Cloud server and a relevant department module. In the method, an information encryption technology based on the attributes is combined, a chain type storage technology is utilized and the security share of personnel archives in the Cloud server is realized with respect to the features of the personnel archives; and a uniform and secure management system for the Internet archives is formed by defining a system model and constructing a plurality of protocols. The data privacy is realized, the interaction of secret keys is reduced and the storage and management of a plurality of secret keys are avoided; the access of the authorization mechanism to the data is limited by setting double barriers; in addition, the system and the method for security management of the Internet archives based on the attributes eliminates the disadvantage that a new method or new software needs to be developed when some kind of information was increased in the past.
