摘要： Discloses are a method for generating a rights object, and a method and apparatus for limiting a rights object. The method for generating a rights object includes: after the rights issuance system receives the rights information relative to the content object, the rights issuance system determines whether the rights object to be generated is a stateful rights object and has copy export permission according to the rights information, and performs subsequent processes for generating the rights object if it is not a stateful rights object or does not have the copy export permission. The rights issuance system further determines whether the rights information includes state limitation information for the copy export permission when the rights object to be generated is a stateful rights object and has the copy export permission. If it does, perform subsequent processes for generating the rights object. Otherwise, abandon the generation of the rights object.

摘要： A method for importing or moving a rights object (RO) is provided, which includes the following steps. A rights issuer (RI) receives a request message of importing or moving an RO to a target device, the request message including key information encapsulated by a public key of the target device; the RI generates the RO according to the request message, the RO including the key information encapsulated by the public key of the target device; and the RI provides the RO for the target device. An RI is also provided. In the present invention, the key information encapsulated by the public key of the target device is provided for the RI, and the real key is hidden from the RI, such that the un-trust RI cannot generate the illegal RO for other devices except the target device, thereby enhancing the security of importing or moving the RO through the RI.
