Description
Technical Field
The invention relates to the technical field of quantum keys, in particular to a 5G module based on a quantum key, a communication system, a communication method and application.
Background
Quantum key distribution is to ensure the security of communication by using quantum mechanical characteristics, which enables two communication parties to generate and share a random and secure key to encrypt and decrypt messages. One of the most important, and unique, properties of quantum key distribution is: if a third party attempts to eavesdrop on the password, both parties to the communication will perceive it. This property is based on the fundamental principle of quantum mechanics, i.e. any measurement of a quantum system will interfere with the system. A third party attempting to eavesdrop on the password must somehow measure it, and these measurements can cause a noticeable anomaly. Information is transmitted through a quantum superposition state or a quantum entanglement state, and a communication system can detect whether eavesdropping exists or not. When the eavesdropping is below a certain standard, a security key can be generated.
With the development of quantum mechanics and the appearance of quantum keys, a truly random and absolutely secure quantum key can further ensure data security, a proper encryption algorithm is selected according to a use scene by using the quantum key to realize data encryption, in order that a user can safely obtain the quantum key, the distribution of the quantum key is absolutely secure according to a BB84 protocol, and both users can obtain a random and secure quantum key. However, the conventional optical fiber-based quantum key distribution is greatly limited in practical application, a special line needs to be established, and the transmission distance is limited, so that the practical use scene of the quantum key is limited, and the conventional optical fiber-based transmission mode is slow and the transmission time is prolonged. Therefore, synchronous key pools are established at two ends of key transmission, and quantum keys are transmitted to a user side in advance.
The 5G module packages hardware such as a 5G chip, radio frequency, storage, power management, etc., provides external package modes such as LGA/m.2, etc., and provides software interfaces such as standard AT, etc., so that a terminal client can perform 5G network connection by directly using the standard interfaces or instructions. The 5G module is added on the equipment, so that the equipment can transmit data through a 5G network. Compare in 4G module, its transmission rate is higher, the time delay is lower, can be applied to FWA, intelligent manufacturing, telemedicine, wisdom city, wisdom traffic, wisdom harbour, car networking, key task emergency communication etc..
However, most of the quantum keys in the synchronous key pool are filled in real time, and new keys are generated for caching when the keys are needed, so that time delay is caused when the keys are obtained; and a large amount of keys are consumed, and the key pool needs to be updated frequently, so that resource waste is caused. The existing 5G module only provides a communication function, and when the module is applied to quantum key communication, a corresponding encryption strategy is lacked, and additional quantum key generation and storage media are still needed.
