Abstract

A new conference key distribution scheme in a in a totally-ordered Hierarchy is proposed in this study. A group of users with a different security class can generate a common secret key over a public channel so that a secure electronic conference can be held. The security classes form a hierarchy such that users in a higher security class can obtain a secret session key with users in the same or lower security classes. However, the opposite situation is not permitted.
