[0081] In some embodiments, the channel state information may include uplink frames sent by the terminal device.

[0082] S120: Identify the terminal device according to the radio frequency signal.

[0083] In some embodiments, the base station may pre-store radio frequency signals of multiple terminal devices. When acquiring the radio frequency signal sent by the terminal device, the base station may compare the radio frequency signal sent by the terminal device with the radio frequency signals of multiple pre-stored terminal devices. If the pre-stored radio frequency signal includes the radio frequency signal sent by the terminal device, it is determined that the above-mentioned terminal device has been identified.

[0084] In some embodiments, the base station may also generate a physical layer fingerprint corresponding to the terminal device based on the acquired radio frequency signal.

[0085] In some embodiments, the base station may compare the acquired physical layer fingerprint of the terminal device with a pre-established physical layer fingerprint library based on an intelligent model or a statistical algorithm. It should be noted that the present disclosure does not specifically limit the intelligent model and the statistical algorithm.

[0086] In some embodiments, the RF signal may include harmonic distortion and DC bias of the Digital-to-Analog Converter (DAC) caused by hardware circuit errors, phase noise of the oscillator, distortion of the intermediate frequency filter, orthogonal offset error and local oscillator (LO) leakage of the mixer, I / Q gain imbalance, and nonlinearity of the power amplifier (PA), differential constellation diagram, uniqueness of carrier frequency offset, etc.

[0088] S130: When the terminal device is recognized successfully, generate a first key based on the channel state information.

[0089] In some embodiments, when the terminal device is identified successfully, the terminal device may initiate a key generation request, and then the base station generates a first key based on the key generation request initiated by the terminal device.

[0090] In some embodiments, the channel state information may include received signal strength (RSS), channel impulse response (CIR) and angle of arrival (AOA).

[0091] The identification method provided by the embodiments of the present disclosure obtains the radio frequency signal and channel state information sent by the terminal device, identifies the terminal device according to the radio frequency signal, generates a first key based on the channel state information when the terminal device is successfully identified, and decrypts the encrypted information sent by the terminal device based on the first key, thereby reducing the user communication delay while ensuring the user privacy.

[0093] like Figure 2 As shown, the identification system may include:

[0094] Legal terminal device 201, illegal terminal device 202 and base station 203;

[0095] The base station 203 may respectively obtain the radio frequency signals sent by the legal terminal device 201 and the illegal terminal device 202, and then identify the radio frequency signals respectively.

[0096] In some embodiments, the illegal terminal device 202 can not only impersonate the legal terminal device 201 to send information to the base station 203 and eavesdrop on the legal user information, but also intercept the legal information on the legal channel and then tamper with it.

[0097] The identification system provided by the embodiments of the present disclosure obtains the radio frequency signal and channel state information sent by the terminal device, identifies the terminal device according to the radio frequency signal, generates a first key based on the channel state information when the terminal device is successfully identified, and decrypts the encrypted information sent by the terminal device based on the first key, thereby reducing the user communication delay while ensuring the user privacy.

[0098] S140: decrypt the encrypted information sent by the terminal device based on the first key.

[0099] In some embodiments, the key used by the terminal device to encrypt the encrypted information is the same as the first key.

[0100] In some embodiments, the identification method may further include:

[0101] If the terminal device fails to pass the identification, the base station will no longer allocate resources to the terminal device.

[0102] In some embodiments, an endogenous security gateway may be set up in the base station, and the endogenous security gateway may execute the above identification method.

[0109] In some embodiments, the channel state information between the terminal device and the base station is the same, and therefore, the second key generated by the terminal device based on the channel state information may be the same as the first key generated by the base station.

[0110] In some embodiments, since the first key is the same as the second key, the base station is able to decrypt the encrypted information based on the first key.

[0111] S350: decrypt the encrypted information sent by the terminal device based on the first key.

[0120] In some embodiments, updating the first key may include acquiring channel state information based on a preset period, and generating an updated first key based on the updated channel state information if the channel state information changes.

[0121] In some embodiments, updating the first key may further include acquiring channel state information based on a preset period, and if the channel state information does not change, keeping the first key unchanged.

[0130] In some embodiments, removing the difference in channel state information acquired by the terminal device and the base station based on the information coordination algorithm may include:

[0131] The terminal device synchronizes the frequency, phase and 10ms frame and the cell with the base station through the binary synchronization signal sequence (such as PSS and SSS) sent periodically by the base station at a specific location. The terminal needs to search for the center frequency of the high-frequency carrier of the cell and synchronize the frequency of the analog signal with the carrier signal. The terminal synchronizes the bit frequency, bit phase and 10ms frame with the 10ms frame of the cell to ensure that the start position of the received data is at the specific position of the 10ms frame.

[0132] In some embodiments, removing the difference in channel state information acquired by the terminal device and the base station based on the information coordination algorithm may include:

[0133] After completing the downlink synchronization, the terminal device determines the time to send the uplink frame and sends the uplink synchronization sequence at that time. The base station receives the uplink synchronization sequence, estimates the relative delay of the round-trip transmission of the terminal wireless link (i.e., the timing advance TA), and feeds it back to the terminal device. After obtaining the estimated TA, the terminal device adjusts the sending time of its uplink frame to achieve uplink synchronization.

[0134] In some embodiments, removing the difference in channel state information acquired by the terminal device and the base station based on the information coordination algorithm may include:

[0135] Synchronization offset is estimated and corrected through signal processing algorithms.

Channel estimation and compensation are performed using channel-level reference signals such as the demodulation reference signal (DM-RS) to reduce the impact of channel changes on communications.

[0136] In some embodiments, removing the difference in channel state information acquired by the terminal device and the base station based on the information coordination algorithm may include:

[0137] Use time synchronization protocols (such as NTP, PTP, etc.) to achieve time synchronization between base stations and terminal devices to ensure that the time bases of both parties are consistent.
