Abstract
In this note, we show that a proposed secure broadcasting scheme is insecur e. We also present a modified scheme to overcome this weakness. The modifie d scheme has the extra advantage that each participant can derive his group keys from group identities without the need of knowing other information. (C) 1999 Elsevier Science BV.
