发明名称 Process for establishing a common cryptographic key for N subscribers
摘要 A process is described which can be used to generate a cryptographic key for a group of subscribers whose number is subject to change. The process can further provide that even after the group key has been established, subscribers can be removed from or added to the key directory without great effort.
