A new key sharing system for global telecommunications
T. Chikazawa, Takayoshi Inoue · 2002
A key sharing system that can be used for communication among multiple users and in which users can share a common key by one-way communication is described. In addition, it is shown to be impossible for any number of users to conspire. The security of the system is based on the difficulty of both factoring a large number and computing discrete logarithms over large finite fields. The system can be applied to various global telecommunication systems.>
