This application relates to a vehicle unlocking and locking system, a passive radio frequency key, and a vehicle, to solve the technical problems of the passive radio frequency key relying on battery power, which leads to the inability to unlock the vehicle when the battery is depleted, and the risks of data leakage and vehicle theft associated with mobile APP keys. When the vehicle body controller is in the wake-up state, the UWB radio frequency unit sends a high-frequency ranging signal and receives a first response signal carrying authentication information returned by the key. The first response signal is generated by the key using energy segmented from the high-frequency ranging signal to process the information carried in the high-frequency ranging signal. The vehicle body controller calculates the distance between the key and the vehicle based on the time difference between signal transmission and reception. When the vehicle is in a partially dormant state, the vehicle body controller generates a vehicle unlocking command based on the distance and the key's authentication result. When the vehicle is in a fully awake state, the vehicle body controller generates a vehicle locking command based on the distance, the key's authentication result, and the vehicle's status information.

This application discloses a quantum-secure communication method and system for the entire Mesh self-organizing network. For any quantum-secure terminal in the Mesh self-organizing network, since the quantum-secure terminal pre-stores the decryption true random numbers corresponding to each one-way receiving relationship and the encryption true random numbers corresponding to each one-way sending relationship in the Mesh self-organizing network, the quantum-secure terminal can perform quantum decryption on the first quantum-encrypted data sent from any sender in the Mesh self-organizing network based on the decryption symmetric true random numbers corresponding to each one-way receiving relationship in the Mesh self-organizing network. Based on the encryption true random numbers corresponding to each one-way sending relationship in the Mesh self-organizing network, it can quantum-encrypt and send the second plaintext data to any receiver in the Mesh self-organizing network, thereby realizing quantum-secure communication between any two quantum-secure terminals in the Mesh self-organizing network and ensuring the communication security of the decentralized Mesh self-organizing network.
