Yuan Ding · Journal of Southwest Jiaotong University · 2002
A security flaw in the conference distribution scheme, namely GDH.2, proposed by M. Steiner et al , is found out, and a new secure and efficient conference key distribution scheme suitable for users exchanging information on insecure communication networks. Compared with GDH.2, the security of this new scheme is greatly improved at the cost of a slight increase in computation and communication loads.
