Abstract
A method, system and terminal for communication between an encryption terminal and an encryption module in a cluster system are provided in the present document. The method includes: when it is required to make an encrypted call, a calling encryption terminal applying to a key management center for a key according to the type of the encrypted call; the calling encryption terminal and a called encryption terminal receiving working keys sent from the key management center, setting respective working states, and synchronizing the working keys and the working states to respective encryption modules; and the encryption module of the calling encryption terminal and the encryption module of the called encryption terminal respectively making an encrypted call by using the working keys. The system includes: a calling encryption terminal, a called encryption terminal and a key management center. The terminal includes: an applying module, a synchronization module and an encryption module.
