Any size of key of the middle variant conversation object of correspondence is not enough, when any of the variant conversation object of correspondence in cipher key storage block
When size of key is less than 15%, the siren sends warning and reminded.
The beneficial effects of the invention are as follows:
Quantum key of the quantum random number generator generation with truly random property is set in intercom and is stored in cipher key storage block, it is right
Say that the intercom of other in system downloads quantum key by the intercom, symmetric key is shared with the intercom；Cipher mode is adopted
With the cipher system of " one-time pad ", i.e., information is encrypted by the way of information and the isometric XOR of key, encryption every time makes
With different encrypted message transmitting procedure unconditional securities；Do not have in the system share identical quantum key intercom between can not
Communication, facilitates the intercom to be scheduled and issue crew's broadcast.
