Description

Technical Field

[0001] This invention relates to the field of network connectivity technology, specifically to a network connectivity method for smart door locks. Background Technology

[0002] With the rapid development of IoT technology, smart locks, as core security devices, have attracted much attention regarding the reliability and security of their network connections. Currently, smart locks typically connect directly to a router to access the network and rely on a single communication link for remote control and alarm functions. However, this single-connection mode presents significant security vulnerabilities: when an attacker technically compromises the lock or maliciously disconnects it from the router, the lock completely loses its network communication capability, preventing alarm signals from being promptly uploaded to the cloud or user terminal, thus causing security failure.

[0003] To address these issues, some technical solutions attempt to introduce redundant network connection mechanisms, such as multi-router switching or cellular network backup. However, such solutions suffer from limitations such as high cost, high energy consumption, and complex configuration, and do not fully consider the dynamic coordination of security and communication performance between devices. Therefore, there is an urgent need for a smart lock network connection method that can dynamically select the optimal auxiliary device within the local area network to construct multi-path redundant communication links while ensuring security. This would allow reliable transmission of abnormal alarm signals through auxiliary devices even when the connection between the lock and the router is severed, thereby improving the smart lock's resistance to attacks. Summary of the Invention

[0004] To address the aforementioned technical issues, a smart door lock network connection method is provided. This technical solution resolves the significant security vulnerabilities inherent in the single connection mode: when an attacker uses technical means to intrude into the door lock or maliciously disconnects it from the router, the door lock will completely lose its network communication capability, resulting in abnormal alarm signals failing to be uploaded to the cloud or user terminal in a timely manner, thus causing security failure.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] A method for connecting a smart door lock to a network, comprising:

[0007] Obtain information on all devices within the local area network to which the router to which the smart door lock is connected. The device information includes at least whether the device supports short-range wireless communication and the types of short-range wireless communication it supports.

[0008] Devices that support short-range wireless communication were selected as candidate auxiliary connection devices;

[0009] Based on the safety performance of the candidate auxiliary connection devices, a safety performance score is given for all candidate auxiliary connection devices.

[0010] Based on the connection status of the candidate auxiliary connection device with the router and the short-range wireless communication connection status with the smart door lock, an additional communication performance score is given to the candidate auxiliary connection device.

[0011] A dynamic assistance period is set. In each dynamic assistance period, based on the security performance score and the additional communication performance score of the candidate auxiliary connection device, and based on the auxiliary election algorithm, at least one candidate auxiliary connection device is selected as the target auxiliary connection device from all candidate auxiliary connection devices.

[0012] Based on the built-in short-range wireless communication module, a short-range wireless communication connection is established between the smart lock and the target auxiliary connection device, thereby realizing the auxiliary connection between the smart lock and the target auxiliary connection device;

[0013] When the smart lock detects abnormal behavior, it simultaneously sends an abnormal alarm signal to the router and the target auxiliary connection device.

[0014] Preferably, the step of scoring the safety performance of all candidate auxiliary connection devices based on their safety performance specifically includes:

[0015] A comprehensive security performance assessment of a device is conducted based on multiple dimensions, including its hardware encryption capabilities, the communication encryption protocols it employs, and access control, to obtain a security performance score for the device.

[0016] The safety performance score range of the device is [0, 1]. The closer the safety performance score of the device is to 1, the higher the safety performance of the device.

[0017] Preferably, the additional communication performance score for the candidate auxiliary connection device based on its connection status with the router and its short-range wireless communication connection status with the smart door lock specifically includes:

[0018] The signal strength, signal-to-noise ratio, communication delay, and packet loss rate of the candidate auxiliary connection device and the router are evaluated respectively. After normalizing the above signal strength, signal-to-noise ratio, communication delay, and packet loss rate, the weighted sum is obtained to obtain the connection status score of the candidate auxiliary connection device and the router.

[0019] All candidate auxiliary connection devices are connected to the smart lock via short-range wireless communication. The communication latency between the smart lock and each candidate auxiliary connection device is tested and normalized to obtain an initial score for the short-range wireless communication connection status between the candidate auxiliary connection devices and the smart lock.

[0020] Based on the historical auxiliary connection records of the candidate auxiliary connection devices and the smart door lock, the ratio of disconnection time to total auxiliary time is calculated to obtain the stability correction value.

[0021] Multiply the stability correction value by the initial score of the short-range wireless communication connection status to obtain the real-time score of the short-range wireless communication connection status between the candidate auxiliary connection device and the smart door lock.

[0022] The communication performance score of the candidate auxiliary connection device is obtained by normalizing and weighting the connection status scores of the candidate auxiliary connection device with the router and the real-time short-range wireless communication connection status scores of the candidate auxiliary connection device with the smart door lock.

[0023] Preferably, the step of selecting at least one candidate auxiliary connection device as the target auxiliary connection device from all candidate auxiliary connection devices based on the auxiliary election algorithm specifically includes:

[0024] Based on the security performance score and the additional communication performance score of the candidate auxiliary connection device, evaluate the auxiliary indicators of the candidate auxiliary connection device;

[0025] An auxiliary correction coefficient is set, which corresponds one-to-one with the candidate auxiliary connection device. The auxiliary correction coefficient decreases as the candidate auxiliary connection device is selected for assistance a certain number of times.

[0026] Multiply the auxiliary correction coefficient by the auxiliary index of the candidate auxiliary connection device to obtain the real-time auxiliary index of the candidate auxiliary connection device;

[0027] The real-time auxiliary indicators of the candidate auxiliary connection device are compared with the real-time auxiliary indicators of all candidate auxiliary connection devices to obtain the real-time auxiliary probability of the candidate auxiliary connection device.

[0028] Based on the real-time auxiliary probability of the candidate auxiliary connection devices, and combined with a dual random algorithm, at least one candidate auxiliary connection device is selected as the target auxiliary connection device from the candidate auxiliary connection devices.

[0029] Preferably, the auxiliary indicators for evaluating the candidate auxiliary connection device based on the security performance score and the additional communication performance score of the candidate auxiliary connection device are specifically evaluated using the TOPSIS algorithm.

[0030] Preferably, the dual random algorithm includes:

[0031] All candidate auxiliary connection devices are randomly sorted, and the auxiliary range of each candidate auxiliary connection device is determined by combining the sorting results and the real-time auxiliary probability of the candidate auxiliary connection devices.

[0032] A random number is generated within the interval [0, 1] as an auxiliary value;

[0033] The candidate auxiliary connection device corresponding to the auxiliary value falling into the auxiliary interval is determined and used as the target auxiliary connection device.

[0034] Preferably, the method for determining the auxiliary interval of the candidate auxiliary connection device is as follows: the auxiliary interval of the candidate auxiliary connection devices ranked N is... , Let i be the real-time auxiliary probability of the candidate auxiliary connection device ranked i.

[0035] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0036] This invention achieves a multi-path redundancy alarm mechanism for smart locks in abnormal scenarios by dynamically selecting and assisting devices with high security and stable communication capabilities within the local area network. It combines security performance scoring, real-time communication status assessment, and a dual random election algorithm. Even if the direct connection between the lock and the router is maliciously cut off, alarm signals can still be relayed through auxiliary devices, effectively resisting the risk of single-point communication failure. At the same time, by utilizing device reuse and short-range low-power communication technology, it improves anti-attack capabilities and alarm reliability while taking into account deployment costs and energy consumption optimization. Moreover, it does not require manual configuration by the user and adapts to dynamically changing network environments. Attached Figure Description

[0044] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0045] Example 1:

[0046] Reference Figure 1 As shown, a smart door lock network connection method includes:

[0047] Obtain information on all devices within the local area network to which the router connected to the smart lock belongs. The device information includes at least whether the device supports short-range wireless communication and the types of short-range wireless communication it supports.

[0048] By actively scanning device information within the local area network and identifying their communication capabilities, we can ensure comprehensive coverage of potentially available auxiliary equipment resources, avoid missing candidate devices that support short-range communication, and provide basic data support for subsequent auxiliary equipment screening.

[0049] Devices that support short-range wireless communication were selected as candidate auxiliary connection devices;

[0050] By excluding devices that do not support short-range communication, the computational overhead of invalid devices participating in the auxiliary election is reduced, while ensuring that candidate devices have the basic ability to communicate directly with the smart lock, thereby improving the success rate and efficiency of the auxiliary connection.

[0051] Based on the safety performance of the candidate auxiliary connection devices, a safety performance score is given for all candidate auxiliary connection devices, specifically including:

[0052] A comprehensive security performance assessment of a device is conducted based on multiple dimensions, including its hardware encryption capabilities, the communication encryption protocols it employs, and access control, to obtain a security performance score for the device.

[0053] The safety performance rating range of the equipment is [0, 1]. The closer the safety performance rating of the equipment is to 1, the higher the safety performance of the equipment.

[0054] By conducting multi-dimensional security assessments of hardware encryption capabilities and communication protocol security, high-security-level auxiliary devices are selected to prevent alarm information from being leaked or hijacked due to security vulnerabilities in the auxiliary devices themselves, thereby improving the overall system's resistance to attacks.

[0055] Based on the connection status of the candidate auxiliary connection device with the router and the short-range wireless communication connection status with the smart door lock, an additional communication performance score is given to the candidate auxiliary connection device, specifically including:

[0056] The signal strength, signal-to-noise ratio, communication delay, and packet loss rate of the candidate auxiliary connection device and the router are evaluated respectively. After normalizing the above signal strength, signal-to-noise ratio, communication delay, and packet loss rate, the weighted sum is obtained to obtain the connection status score of the candidate auxiliary connection device and the router.

[0057] All candidate auxiliary connection devices are connected to the smart lock via short-range wireless communication. The communication latency between the smart lock and each candidate auxiliary connection device is tested and normalized to obtain an initial score for the short-range wireless communication connection status between the candidate auxiliary connection devices and the smart lock.

[0058] Based on the historical auxiliary connection records of the candidate auxiliary connection devices and the smart door lock, the ratio of disconnection time to total auxiliary time is calculated to obtain the stability correction value.

[0059] Multiply the stability correction value by the initial score of the short-range wireless communication connection status to obtain the real-time score of the short-range wireless communication connection status between the candidate auxiliary connection device and the smart door lock.

[0060] The communication performance score of the candidate auxiliary connection device is obtained by normalizing and weighting the connection status score between the candidate auxiliary connection device and the router and the real-time score of the short-range wireless communication connection status between the candidate auxiliary connection device and the smart door lock.

[0061] By combining dynamic indicators such as real-time signal strength and historical connection stability, the reliability of device communication can be accurately assessed, ensuring that the selected auxiliary equipment can maintain a stable relay communication link in abnormal scenarios and avoid the loss of alarm signals due to poor communication quality.

[0062] A dynamic assistance period is set. In each dynamic assistance period, based on the security performance score and the additional communication performance score of the candidate auxiliary connection device, and based on the auxiliary election algorithm, at least one candidate auxiliary connection device is selected as the target auxiliary connection device from all candidate auxiliary connection devices.

[0063] By periodically and dynamically reselecting auxiliary devices, the system avoids auxiliary failures caused by device offline, changes in network environment, or degraded security status. Combined with a dual scoring mechanism for security and communication, the system ensures that the optimal device is continuously selected, thereby improving the system's adaptive capabilities.

[0064] Based on the built-in short-range wireless communication module, a short-range wireless communication connection is established between the smart lock and the target auxiliary connection device, thereby realizing the auxiliary connection between the smart lock and the target auxiliary connection device;

[0065] Utilize short-range wireless communication technologies, such as Bluetooth and ZigBee, to achieve low-power, high-response-speed auxiliary connections;

[0066] When the smart lock detects abnormal behavior, it simultaneously sends an abnormal alarm signal to the router and the target auxiliary connection device.

[0067] With a dual-path parallel alarm mechanism, even if an attacker cuts off the direct connection between the smart lock and the router, the alarm signal can still be relayed through auxiliary equipment, completely eliminating the risk of single-point communication failure and significantly improving the reliability and anti-interference capability of abnormal alarms.

[0068] Example 2:

[0069] Reference Figure 2 As shown, based on Embodiment 1, this embodiment further proposes an auxiliary election algorithm to select at least one candidate auxiliary connection device as the target auxiliary connection device from all candidate auxiliary connection devices. Specifically, this includes:

[0070] Based on the security performance score and the additional communication performance score of the candidate auxiliary connection device, evaluate the auxiliary indicators of the candidate auxiliary connection device;

[0071] Set an auxiliary correction coefficient, which corresponds one-to-one with the candidate auxiliary connection device. The auxiliary correction coefficient decreases as the candidate auxiliary connection device is selected for assistance more often.

[0072] Specifically, the auxiliary correction factor can be calculated as follows:

[0073] .

[0074] in, As an auxiliary correction factor, To reduce damping, The number of times the assistant was selected;

[0075] The auxiliary correction coefficient adopts a dynamic zeroing mechanism. Within the set dynamic cycle, the correction coefficients of all devices are cleared to zero, and the auxiliary correction coefficients are recalculated in the next dynamic cycle.

[0076] By designing an auxiliary correction coefficient, high-auxiliary-index devices are prevented from being repeatedly selected and thus captured by attackers. The auxiliary correction coefficient is used to adjust the probability of each device being selected for auxiliary, thereby reducing the probability of auxiliary devices being captured and further improving the line security of auxiliary connections.

[0077] Multiply the auxiliary correction coefficient by the auxiliary index of the candidate auxiliary connection device to obtain the real-time auxiliary index of the candidate auxiliary connection device;

[0078] The real-time auxiliary indicators of the candidate auxiliary connection device are compared with the real-time auxiliary indicators of all candidate auxiliary connection devices to obtain the real-time auxiliary probability of the candidate auxiliary connection device.

[0079] Based on the real-time auxiliary probability of the candidate auxiliary connection devices, and combined with a dual random algorithm, at least one candidate auxiliary connection device is selected as the target auxiliary connection device from the candidate auxiliary connection devices.

[0080] By introducing an auxiliary correction coefficient to dynamically adjust the probability of device selection, and combining a dynamic zeroing mechanism with a dual random algorithm, the risk of high-scoring auxiliary devices exposing their communication paths due to frequent selection is effectively avoided, reducing the possibility of attackers targeting or hijacking auxiliary devices. The decay design of the auxiliary correction coefficient prompts the system to automatically rotate candidate devices, balance the auxiliary load and disperse potential attack surfaces. At the same time, through real-time auxiliary probability calculation and random election strategy, the randomness and unpredictability of auxiliary link selection are enhanced while ensuring the optimal overall performance of auxiliary devices. This achieves a dynamic balance between device security, communication stability and path concealment, significantly improving the overall anti-attack capability and long-term operational reliability of auxiliary connections.

[0081] Example 3:

[0082] Building upon Example 2, this solution further proposes evaluating the auxiliary indicators of the candidate auxiliary connection device based on its security performance score and additional communication performance score. Specifically, the TOPSIS algorithm is used, and the detailed steps are as follows:

[0083] The maximum security performance score and the maximum additional communication performance score are selected to form an auxiliary optimal solution;

[0084] The minimum security performance score and the minimum additional communication performance score are selected to form an auxiliary worst solution;

[0085] Based on the security performance score and the distance between the additional communication performance score of each candidate auxiliary connection device and the auxiliary optimal and auxiliary worst solutions, the auxiliary indicators of the candidate auxiliary connection devices are obtained. The specific calculation formula is as follows:

[0086] .

[0087] In the formula, For the j-th candidate auxiliary connection device, To assist in finding the optimal solution, To assist in finding the worst solution, Score the safety performance of the j-th candidate auxiliary connection device. Add a communication performance score to the j-th candidate auxiliary connection device. To find the vector distance function.

[0088] By employing the TOPSIS algorithm to comprehensively evaluate the security and communication performance of auxiliary equipment from multiple dimensions, the algorithm quantifies the distance between the equipment score and the optimal and worst solutions, avoiding the subjective bias of traditional weighted scoring methods and achieving objective ranking and dynamic optimization of equipment performance. This algorithm balances security and communication capabilities, preventing the misselection of high-security, low-communication or high-communication, low-security equipment due to a single indicator, while accurately selecting auxiliary equipment with comprehensive performance closest to the ideal optimal solution. Furthermore, by combining dynamic auxiliary cycles and auxiliary correction coefficients, it ensures that the global optimal solution is always used as the benchmark during equipment rotation, effectively resisting attackers' long-term targeting or path prediction of fixed high-scoring equipment. This further enhances the scientific nature and reverse engineering resistance of auxiliary link selection, ultimately improving the reliability of abnormal alarm signal transmission and the overall robustness of the system.

[0089] Example 4:

[0090] Reference Figure 3 As shown in Example 2, this example further points out that:

[0091] Double randomization algorithms include:

[0092] All candidate auxiliary connection devices are randomly sorted, and the auxiliary range of each candidate auxiliary connection device is determined by combining the sorting results and the real-time auxiliary probability of the candidate auxiliary connection devices.

[0093] The method for determining the auxiliary range of the candidate auxiliary connection devices is as follows: the auxiliary range of the candidate auxiliary connection devices ranked N is... , The real-time assist probability of the candidate auxiliary connection device ranked i;

[0094] A random number is generated within the interval [0, 1] as an auxiliary value;

[0095] The candidate auxiliary connection device corresponding to the auxiliary value falling into the auxiliary interval is determined and used as the target auxiliary connection device.

[0096] By combining two random algorithms, the real-time auxiliary probability of candidate devices is transformed into a dynamic auxiliary interval. A probability distribution selection mechanism is then superimposed on the random sorting, preventing attackers from predicting device selection patterns based on historical auxiliary records and completely avoiding the risk of a fixed device selection path. The probability mapping design of the auxiliary interval ensures that high-scoring devices still have a higher probability of being selected, while introducing unpredictability through random number generation to prevent attackers from targeting or hijacking high-security devices. Simultaneously, it balances the auxiliary load of multiple devices, preventing a single device from becoming a security vulnerability due to frequent use. This algorithm improves the concealment of the auxiliary link while balancing selection efficiency and system resource consumption, achieving dual optimization of security and real-time performance. It significantly enhances the resistance to reverse analysis and long-term monitoring of the abnormal alarm transmission path.

[0099] In summary, the advantages of this invention are as follows: By dynamically selecting and assisting devices with high security and stable communication capabilities within the local area network, and combining security performance scoring, real-time communication status assessment, and dual random election algorithms, a multi-path redundancy alarm mechanism for smart locks in abnormal scenarios is realized. Even if the direct connection between the lock and the router is maliciously cut off, alarm signals can still be relayed through auxiliary devices, effectively resisting the risk of single-point communication failure. At the same time, by utilizing device reuse and short-range low-power communication technology, while improving anti-attack capabilities and alarm reliability, deployment costs and energy consumption optimization are also taken into account.
