Abstract
The disclosure is directed to reduce a load of time and cost at the time of transition to a safer system in which an encryption scheme is newly set. By allowing a device of a transition step which implements a predetermined security reinforcement measure to handle high-value content only for a given system transition period, a problem of a time necessary for the transition can be avoided and the transition to the safer system can be performed smoothly. The device mentioned herein which implements the predetermined security reinforcement measure is, for example, a device which supports only an existing encryption algorithm and for which security of a weaker portion other than the encryption scheme is ensured.
