发明名称 Secure storage on recordable medium in a content protection system
摘要 An application on a computing device to write data to a storage medium associated therewith. The data is to be written to a secure storage area associated with an object on the storage medium, and the secure storage area has a value storage area associated therewith. The application generates a nonce and employs a shared session key (KS) to encrypt the nonce to result in (KS(nonce)). The storage medium receives same and decrypts with (KS) to result in the nonce, locates the value storage area associated with the secure storage area, and stores such nonce in the located value storage area. The application employs the nonce to generate a key (KH), encrypts the data with (KH) to result in (KH(data)), and sends same to the storage medium for storage in the secure storage area. Thus, (KH(data)) is associated with the nonce in the value storage area.
