    摘要： An authentication communication system includes an storage medium having an area for storing digital information and an access device for reading/writing digital information from/into the area. The access device authenticates whether the storage medium is authorized according to a challenge-response authentication protocol in which scrambled access information generated by scrambling the access information which shows the area is used. The storage medium authenticates whether the access device is authorized. When the access device and the storage medium have authenticated each other as authorized devices, the access device reads/writes digital information from/into the area in the storage medium according to the access information separated from the scrambled access information by the access device.

    摘要： A device and method for encrypting content in an encryption device including a content-key storage section is disclosed. The method includes generating a content-key used for encrypting content based on random numbers and storing the generated content-key in the content-key storage section, encrypting the content-key used for encrypting the content so as to obtain an encrypted content-key and outputting the encrypted content-key to outside of the encryption device, determining whether or not a value of the content-key storage section in its initial state and a current value of the content-key storage section are different, and when it is determined that the value of the content-key storage section in its initial state and the current value of the content-key storage section are different, encrypting the content using the current value of the content-key storage section as a content-key so as to obtain a second output data and output the second output data to outside of the encryption device, wherein, for the determination step, a register stores a value of the content-key storage section at the time that said register receives a Power On Reset (POR) signal, and wherein the POR signal is a signal which pulses only once immediately after power-on or immediately after reset, so that the content-key storage section is in an initial state immediately after a corresponding power-on or reset of the encryption device.
