Embodiment 1

[0044] Embodiment 1: Realize quantum communication between two mobile communication terminals accessing the Internet through the same base station

[0045] figure 1 A base station-based quantum communication system for mobile communication terminals is shown, mainly including mobile communication terminal A, mobile communication terminal B, and a base station. The mobile communication terminals A and B are both equipped with true random number generators. The base station in this system includes the main functional modules of the cell base station under the existing wireless network, and also needs to include a single-photon emission module and a single-photon detection module. The single-photon emission module can modulate the polarization state of photons according to the control signal, and send the modulated photon strings to the receiver in sequence according to a certain time interval; the single-photon detection module can detect the polarization state of the received p...

Abstract

The invention provides a mobile communication terminal quantum communication method and system based on a base station, and the method employs the base station as a relay of a mobile communication terminal so that two mobile communication terminals which are not provided with quantum key distribution equipment to achieve quantum communication based on BB84 through the base station. According to the invention, a mobile communication scheme based on the base station is provided for different application scenes, and the communication security between mobile terminals such as a mobile phone and the like is greatly improved.

Description

technical field [0001] The invention relates to the field of quantum communication, in particular to a base station-based mobile communication terminal quantum communication method and system. Background technique [0002] Quantum key distribution (QKD) is based on the basic principles of quantum mechanics. The quantum key it transmits cannot be cracked and has unconditional security. Its security is much higher than that of RSA and other cryptographic systems based on difficult problems in number theory. In the prior art, there are many scenarios where quantum key distribution (QKD) technology is used to realize quantum communication, but all of them are realized based on the installation of QKD equipment by both communicating parties. However, for some small mobile communication terminals, such as mobile phones, due to the large size and high price of QKD equipment, QKD equipment has not yet been integrated into such small communication terminals. Therefore, small mobile p...
