On the design of conference key distribution systems for the broadcasting networks
Chi‐Sung Laih, Sung‐Ming Yen · 2002
A design methodology for conference-key distribution systems (CKDSs) that is based on the threshold scheme for broadcasting networks is proposed. It is shown that if a conference chairman can share a secret key with each of the other conference participants, then any threshold scheme can be used to construct a CKDS. Since there already exist many identification (ID)-based key distribution systems for two users sharing a common secret key, ID-based CKDSs can easily be constructed for broadcasting networks.>
