摘要： A conditional access broadcast system for realizing conditional access while maintaining the safety level is disclosed. A contract management device at a broadcast station side delivers a reception contract information containing at least a contract information for controlling decryption of encrypted contents information delivered from a broadcast station by broadcast and a reception device ID in correspondence, which is encrypted using a master key which is commonly provided with respect to all the broadcast reception devices. At each broadcast reception device, whether or not to give a channel key for decrypting the encrypted contents information to the decryption unit is controlled according to the contract information for own broadcast reception device which is acquired from the encrypted reception contract information.

摘要： An information recording apparatus comprises an encryption section encrypting contents information and also a license condition referred to limit use of the contents information and a decoding key for decoding the encrypted contents information to generate license information, and a recording section recording the encrypted contents information and the generated license information on a recording medium. An information reproducing apparatus comprises a decoder unit decoding the license information recorded on the recording medium using a second decoding key for decoding the license information and deciding on the basis of the license condition contained in the decoded license information whether the contents information can be used. If it is decided that the contents information can be used, the encrypted contents information recorded on the recording medium is decoded using the first decoding key contained in the decoded license information.
