Universe quantum personal security terminal and communication system thereof

The invention discloses a global quantum personal security terminal and a communication system thereof. The universal personal terminal can be connected with the global quantum personal safety terminal to perform quantum safety communication with an external network, the universal personal terminal does not need to be transformed or replaced, and when quantum safety communication does not need to be performed subsequently, the universal personal terminal can perform quantum safety communication with the external network. The universal personal terminal and the global quantum personal safety terminal only need to be disconnected, communication of different safety requirements of the universal personal terminal is achieved, and safety of communication of the universal personal terminal is improved. The network switching control module of the global quantum personal security terminal comprises a switching control unit and a network unit, and the switching control unit is not only responsible for realizing data i
