Abstract

In this letter, we show that Jung's ID-based scheme, which is the improved version of the Chikazawa-Yamagishi scheme, satisfies only the weak forward secrecy. But the weak forward secrecy is not quite realistic, since it is not sufficient for modeling the real attacks. To address this problem, the strong forward secrecy has been pursued, which is modeling the more realistic attacks. We then suggest a modification of Jung's ID-based scheme to provide the strong forward secrecy.
