摘要： The present invention relates to a content protection apparatus and method using binding of additional information to an encryption key. The content protection apparatus includes an encryption unit for creating an encryption key required to encrypt data requested by a user terminal and then generating encrypted data in which the data is encrypted. An additional information management unit manages additional information including authority information about the encrypted data. A White-Box Cryptography (WBC) processing unit generates a WBC table required to bind the encryption key corresponding to the encrypted data to the additional information. A bound data generation unit generates bound data in which the encrypted key is bound to the additional information, using a cipher included in the WBC table.

摘要： An apparatus for providing security functions in a computing system includes: at least one normal service domain executing service; a secure service domain performing integrity verification on a service execution environment of at least one normal service domain, and performing the security service function for the service in accordance with the result of the integrity verification; and a virtual machine monitor separating service execution environments of at least one normal service domain and the secure service domain, respectively, based on the same hardware device. According to the present invention, it is possible to enhance the security for execution environments of the computing system and the data stored in the system, by allowing the corresponding services, which need security service functions in the normal service domain, to be executed necessarily only when integrity verification of the execution environment succeeds by linking the secure service domain.
