Several ID-based key distribution schemes can be used to realize secure broadcasting systems. Unfortunately, none of the proposed schemes provide both security against long-term key reveal attacks and security against session state reveal attacks. In this letter, we suggest an ID-based key distribution scheme secure against long-term key reveal attacks and session state reveal attacks.

Jeong et al. recently have proposed a strong ID-based key distribution scheme in order to achieve security against long-term key reveal and session state reveal attacks. In this letter, we show that, unfortunately, the ID-based key distribution scheme is vulnerable to an impersonation attack such that anyone can manipulate public transcripts generated by a user to impersonate the original user.
