Abstract:
     The device is composed of plug-in board and pins of supplying power for the board. In the board, socket of phone leadin, socket of serial communications interface, socket of LED operation indicator, socket of ready button and socket of hand-reset button are installed. The device works in cooperation with the safe device of automatic transmitting cipher key of chaos enciphering communication system. Subsequent multiple deciphering processing is carried out after signal of multiple encrypting keys is received from transmission party through telephone line. Nonvolatile memory stores the resolved original cipher key, which is provided to chaos enciphering communication for further declassifying. The procedure is completed in independent safe channel automatically with no manual work. The invention raises intellectualized degree and security.
