Abstract :
For communication among multiple entities, Chikazawa, and Inoue (1990) published an identity-based one-way key sharing system. However, Simbo and Kawamura (1991) developed an attack which can derive the secret information of entities through a conspiracy of other entities in the system. The present authors propose an improved identity-based one-way conference key sharing system to counter their attack by giving entities unique random numbers
