See full text

A data transmission method and apparatus for transmitting data, such as encrypted content data. A device that is to be a destination of transmission is authenticated. If the device has not been authenticated, encrypted data read out from a storage unit is decrypted to give decoded data which then is re-encrypted based on innate key data acquired from the device that is to be the destination of transmission to give re-encrypted data. The re-encrypted data is then transmitted to the device that is to be a destination of transmission.
