[0048] Figure 1 The authentication method of an embodiment of the present disclosure is shown, and the authentication method can be applied to the authentication device 2, which is any device that needs to be authenticated, such as but not limited to a smart door lock or a garage access control device. Figure 2a, the authentication device 2 includes a long-wave receiving module 21, a main control module 22, a keyboard password module 23, a prompt sound module 24 and a motor module 25. Of course, the authentication device 2 usually also includes other modules, such as a fingerprint module, an NFC module, etc., which are not limited in this embodiment. Generally, the main control module 22 can be used to connect electronic devices such as mobile phones so that the authentication device and the electronic device can communicate. The main control module 22 can be a Bluetooth main control module (BT SoC), which is used to connect electronic devices via Bluetooth so that the authentication device 2 and the electronic device can communicate via Bluetooth.

[0049] like Figure 1 As shown, the authentication method of this embodiment may include the following steps S1100 to S1300:

[0050] Step S1100, obtaining current time information according to the long wave signal received by the long wave receiving module.

[0051] Among them, the authentication device includes a long-wave receiving module. The long-wave receiving module uses long-wave timing technology. Long-wave timing technology can transmit time information through long-wave signals. It has the characteristics of wide coverage, strong anti-interference ability, and high time accuracy. It is very suitable for use in scenarios without network environment or temporary visitors.

[0052] Reference Figure 2b The long-wave receiving module 21 includes a radio frequency control unit 211, a low-noise amplifier (Low-NoiseAmplifier, LNA) 212, an analog-to-digital converter (Analog-to-Digital Converter, ADC) 213 and a digital signal processing unit (Digital Signal Processing, DSP) 214. Among them, the radio frequency control unit 211 is used to receive the long-wave signal. The low-noise amplifier 212 is used to amplify the long-wave signal. The analog-to-digital converter 213 is used to perform analog-to-digital conversion on the long-wave signal to obtain a digital signal. The digital signal processing unit 214 is used to demodulate the digital signal and output a beat digital signal composed of high and low levels.

[0053] Among them, the long-wave signal can be a signal based on binary phase code (BPC) encoding. BPC encoding is a specific timing method based on the long-wave band and applying low-frequency time code. The long-wave signal in China is usually transmitted at a frequency of 68.5khz. In long-wave timing, BPC encoding, as a low-frequency time code, is transmitted through long-wave timing technology and can be used to transmit time information. For BPC encoding, refer to the following embodiments. Correspondingly, before executing this step S1100 to obtain the current time information according to the long-wave signal received by the long-wave receiving module, the authentication method of the embodiment of the present disclosure further includes: receiving the long-wave signal obtained based on BPC encoding through the long-wave receiving module.

[0054] In this embodiment, the long-wave receiving module of the authentication device receives the long-wave signal obtained based on the BPC coding. The main control module of the authentication device can obtain the current time information according to the long-wave signal.

[0055] In an optional embodiment, the step S2100 of obtaining the current time information according to the long wave signal received by the long wave receiving module may further include: obtaining the current time information according to the long wave signal received by the long wave receiving module when the set password update time arrives.

[0056] The password update time is set to update the random temporary password, that is, when the password update time is reached, the main control module can obtain the current time information according to the long wave signal received by the long wave receiving module, so as to calibrate the local real-time clock RTC time according to the current time information, and generate a random temporary password based on the calibrated local RTC time to authenticate the user. Generally, the password update time can be 1 minute or other time, which is not specifically limited in this embodiment.

[0057] Optionally, when the set password update time arrives, obtaining the current time information according to the long-wave signal received by the long-wave receiving module can further include: when the set password update time arrives, demodulating the received long-wave signal through the long-wave receiving module to obtain a beat digital signal; starting the timer and the interrupt detection pin, and when the first interrupt signal is detected through the interrupt detection pin, resetting the timer and starting timing; when the second interrupt signal is detected through the interrupt detection pin, reading the current timing duration of the timer and stopping timing; when the current timing duration is within the set duration range, determining that the second interrupt signal is a starting positioning signal of a frame of beat digital signal, resetting the interrupt detection pin and the timer, and capturing the beat digital signal of the set number of frames through the interrupt detection pin; decoding the captured beat digital signal to obtain the current time information.

[0058] Among them, the beat digital signal is a digital signal composed of high and low levels, and the beat digital signal is usually composed of a positioning signal and a data signal.

[0059] The set duration range can usually be set to 990ms to 1010ms, that is, the main control module can usually detect the start positioning signal of a frame of beat digital signal within the range of 990ms to 1010ms.

[0060] Specifically, when the set password update time arrives, the main control module controls the long-wave receiving module to demodulate the received long-wave signal, obtain the beat digital signal, and start the timer of the main control chip and activate the interrupt detection pin connected to the long-wave receiving module. When the main control chip detects the first interrupt signal through the interrupt detection pin, it will reset the timer and start timing. When the main control chip detects the second interrupt signal through the interrupt detection pin, it will read the current timing duration of the timer as the timing duration since the first interrupt signal. When the current timing duration is between 990ms and 1010ms, the main control module determines that the second interrupt signal is the starting positioning signal of a frame of beat digital signal. The main control module resets the interrupt detection pin and the 20s timer, and captures a frame of beat digital signal through the interrupt detection pin every 20s, and captures a total of three frames of beat digital signal. This is because each frame of beat digital signal in BPC encoding is about 20 seconds long, and a total of three frames of beat digital signal are received for 1 minute. The current time information is obtained after decoding. In BPC coding, different states of pulse width represent different quaternary values. Specifically, pulse widths of 0.1 seconds, 0.2 seconds, 0.3 seconds, and 0.4 seconds represent quaternary 0, 1, 2, and 3, respectively. According to the BPC protocol, the 4th and 5th pulses of a frame represent the current hour, the 6th, 7th, and 8th pulses represent the current minute, and so on to obtain the current time information.

[0061] After executing the above step S1100 to obtain the current time information according to the long wave signal received by the long wave receiving module, enter:

[0062] Step S1200, calibrating the local real-time clock RTC time according to the current time information, and generating a random temporary password based on the calibrated local real-time clock time and the set encryption algorithm.

[0063] The local real-time clock RTC time is used to track the current time and date, and the local real-time clock RTC time can be used to generate a random temporary password to authenticate the user.

[0064] The random temporary password is usually a six-digit password. Of course, it can also be a password of other digits, which is not limited in this embodiment.

[0065] The encryption algorithm is set to a time-based one-time password TOTP algorithm, which can calculate a random temporary password based on a shared key and a local real-time clock RTC time.

[0066] In this embodiment, after obtaining the current time information, the main control module can update the local real-time clock RTC time based on the current time information, so as to generate a random temporary password for user authentication based on the updated local real-time clock RTC time.

[0067] Specifically, the main control module obtains the shared key from the electronic device in advance and stores it. The main control module first calibrates the local real-time clock RTC time based on the current time information, and calculates a random temporary password based on the calibrated local real-time clock RTC time and the shared key through the TOTP algorithm.

[0068] After executing the above step S1200 to calibrate the local real-time clock time according to the current time information, and generating a random temporary password based on the calibrated local real-time clock time and the set encryption algorithm, enter:

[0069] Step S1300: authenticating the user according to the random temporary password.

[0070] In this embodiment, after calculating the random temporary password, the main control module can perform authentication based on the random temporary password.

[0071] In an optional embodiment, the step S1300 of authenticating the user according to the random temporary password may further include the following steps S1310 to S1340:

[0072] Step S1310, obtaining the password currently input by the user.

[0073] In this step S1310, the electronic device, such as a mobile phone, will also calculate the same random temporary password using the auth software and inform the user. The user can enter the random temporary password calculated by the electronic device through the keyboard password module of the authentication device.

[0074] Step S1320: compare the currently input password with the random temporary password to obtain a comparison result.

[0075] In step S1320, the main control module compares the password input by the user with the random temporary password calculated by the main control module this time to obtain a comparison result, wherein the comparison result may be that the password input by the user is the same as the random temporary password calculated by the main control module this time, or that the password input by the user is different from the random temporary password calculated by the main control module this time.

[0076] Step S1330: When the comparison result indicates that the currently input password is the same as the random temporary password, execute the target operation.

[0077] The target operation may include: sending an unlocking signal to a motor module of the authentication device to control the authentication device to unlock through the motor module.

[0078] In this step S1330, when the comparison result shows that the password input by the user is the same as the random temporary password calculated by the main control module this time, the main control module can send an unlocking signal to the motor module, and the motor module can control the authentication device to unlock.

[0079] Step S1340: When the target operation is completed, determine that the user has passed the authentication.

[0080] In this step S1340, when the motor module controls the authentication device to unlock successfully, the main control module determines that the user has completed the authentication.

[0081] It should be noted that, when the motor module controls the authentication device to unlock successfully, the main control module will also control the prompt sound module of the authentication device to play the corresponding prompt sound of successful unlocking.

[0082] Through the disclosed embodiment, it proposes an authentication method based on long-wave timing technology. Long-wave timing has stronger anti-interference ability and improves authentication security. Moreover, by obtaining the current time information through the long-wave receiving module, authentication can be achieved even in a network-free environment. Furthermore, the long-wave timing technology provides high-precision time synchronization capability. In this way, the local real-time clock time is calibrated according to the current time information obtained by the long-wave receiving module, and a random temporary password is generated, which improves the reliability of authentication. In other words, the authentication method based on the disclosed embodiment uses high-precision time synchronization to generate a random temporary password, which improves the reliability and security of authentication and reduces the dependence on the network.

[0083] <Example>

[0084] Next, a flowchart of an example authentication method is shown. In this example, reference Figure 3 , the authentication method includes:

[0085] Step 301: The main control module obtains the shared key of the TOTP algorithm in advance through Bluetooth communication with the mobile phone and stores it.

[0086] Step 302: The long-wave receiving module receives the long-wave signal obtained by BPC coding.

[0087] Step 303, when the set password update time arrives, the main control module activates the long wave receiving module to demodulate the long wave signal to output a beat digital signal, starts the timer of the main control module, and activates the interrupt detection pin connected to the main control module and the long wave receiving module.

[0088] Step 304: When the main control module detects the first interrupt signal through the interrupt detection pin, the main control module resets the timer and starts timing.

[0089] Step 305, when the main control module detects the second interrupt signal through the interrupt detection pin, it reads the current timing duration of the timer and detects whether the current timing duration is between 990ms and 1010ms. If so, execute step 306, otherwise, execute step 304.

[0090] Step 306, the main control module determines that the second interrupt signal is the starting positioning signal of a frame of beat digital signal, and resets the interrupt detection pin and the timer, and captures a frame of beat digital signal every 20 seconds through the interrupt detection pin, and captures a total of three frames of beat digital signal.

[0091] Step 307: The main control module decodes the three-frame beat digital signal based on the BPC coding rule to obtain current time information.

[0092] Step 308: The main control module calibrates the local RTC time according to the current time information, and generates a random temporary password based on the shared key and the calibrated local RTC time by setting an encryption algorithm.

[0093] Step 309, the main control module obtains the password currently input by the user, and when the currently input password is the same as the above-mentioned random temporary password, determines that the switch lock signal is an unlocking signal, and sends an unlocking signal to the motor module. When the authentication device is unlocked successfully through the motor module, it is determined that the user has completed the authentication.

[0094] Through this example, the authentication method of this example has the following technical effects: First, authentication capability in a network-free environment: it obtains the current time information through the long-wave receiving module, and can achieve authentication even in a network-free environment, which greatly expands the application scope of the authentication technology. Second, high-precision time synchronization: the long-wave timing technology provides high-precision time synchronization capability, ensuring that the time-based encryption algorithm can generate accurate random temporary passwords, and improving the reliability of authentication. Third, enhanced security: the transmission characteristics of long-wave timing make the authentication method disclosed in this disclosure have stronger anti-interference ability, reduce the risk of being attacked by hackers, and thus improve the overall security. Fourth, flexibility and practicality: considering the application requirements in different scenarios, it has good flexibility and practicality, and can adapt to various security authentication scenarios such as smart door locks and garage access control. Fifth, cost-effectiveness: compared with the authentication method that relies on network connection, it reduces the dependence on network infrastructure, reduces deployment and maintenance costs, and provides equal or even higher security performance. Sixth, easy integration: the long-wave receiving module is easy to integrate and deploy, without the need for large-scale transformation of existing authentication equipment.
