GLOBAL QUANTUM SECURITY DEVICE, DATA SENDING METHOD AND DATA RECEIVING METHOD

The present application provides a global quantum security device, a data sending method and a data receiving method. Quantum encryption and decryption of data in need of a quantum encryption service can be realized by a quantum encryption and decryption module, thereby ensuring that data received from and sent to a traditional network by the global quantum security device is transmitted in ciphertexts, and guaranteeing the security of data transmission in the traditional network. The communication module is a module which is in the global quantum security device and capable of communicating with an external network. The isolation module can isolate the communication module from the quantum encryption and decryption module and the privacy module respectively, and prevent external network data received by the communication module from compromising the security of the privacy module and the quantum encryption and decryption module. Since the privacy module does not communicate with the external network, and dat
