Abstract
We show that the capacity region of the broadcast channel with confidential messages does not change when the strong security criterion is adopted instead of the weak security criterion traditionally used. We also show a construction method of coding for the broadcast channel with confidential messages by using an arbitrary given coding for the broadcast channel with degraded message sets.
