| Abstract: | Abstract In 1993, Wu and Yeh proposed a conference key distribution system based on cross product. In this paper, we will show that Wu and Yeh's system is breakable. We also propose a modified scheme for the conference key distribution system under the same assumption, which can achieve better security. |
