[0002] In the current Internet of Things (IoT) environment, embedded smart lock systems are widely used in security management of homes, offices, and various facilities. Existing smart lock communication systems usually rely on network connections and cloud services for remote control and status monitoring. However, these systems have some significant problems, especially in terms of security. For example, many smart lock systems communicate with users' mobile devices or other terminals through wireless networks, which makes them vulnerable to man-in-the-middle attacks, unauthorized access, and data leakage.

[0003] A key technical problem is that the existing smart lock system has insufficient security protection capabilities and is difficult to effectively prevent unauthorized access. In traditional solutions, although encrypted communication and user authentication mechanisms are used, there may still be loopholes when facing complex network attacks. Especially when it comes to key management and behavior monitoring, existing technologies often lack sufficient dynamics and real-time performance, resulting in the system being unable to respond in time and take protective measures once an abnormal situation occurs. Summary of the invention

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

The secure communication line is equipped with a key change facility to periodically adjust the communication key. The behavior monitoring unit is used to track communication activities throughout the entire process, immediately stop operations in the event of an abnormal situation, and issue an alarm to the core control node. All interaction records are stored in a tamper-proof log library. After each verification is completed, a temporary authorization code generation device provides a single-use access permit.

[0019] The present invention ensures accurate identification and secure transmission of external change signals through core control nodes and environmental perception units; the information encoding conversion station implements advanced protective processing to enhance the confidentiality and integrity of information transmission. The access confirmation port not only compares stored data with received information, but also generates a single-use temporary authorization code, thereby enhancing the security of access control. The status reporting component and the confidential communication line ensure the secure transmission of feedback messages, while the key change facility periodically adjusts the communication key, reducing the risk of long-term use of the same key. The behavior monitoring unit monitors the communication process in real time, and immediately interrupts the operation and sends an alarm to the core control node when abnormal behavior is detected, thereby improving the response speed and security of the system. The tamper-proof log library saves all interaction records to ensure that events are traceable and facilitate subsequent auditing and analysis.

[0020] In this embodiment, the core control node is used to perform the following steps: Receive the original signal from the environmental sensing unit and convert it into a digital format through a conversion process; the conversion process uses the formula SD=SC*(VMAX-VMIN) / RMAX, where SD is the digital signal strength, SC is the original signal strength, VMAX and VMIN are the preset maximum and minimum voltage values, and RMAX is the maximum resistance value; The converted digital signal SD is passed to the information encoding conversion station, and the information is subjected to protective processing; the protective processing involves generating a random number sequence N, whose length L is determined by the formula L=log2(C+1), where C is the expected number of combinations; The protected information is sent to the access confirmation port, which compares the stored data with the received information. The comparison and analysis uses a hash operation H, which is calculated as H=SHA-512(SD||N). SHA-512 is a hash operation, SD is a digital signal, and N is the random number sequence generated in step b. If the match is successful, the access confirmation port activates the command execution area, parses and responds to the corresponding instructions. During the process, the verification value VH will be calculated. The calculation method is VH=XOR(H,K), where XOR is an exclusive OR operation, H is the obtained hash value, and K is a pre-set key.

[0021] Steps and formula application of core control nodes Receive and convert the raw signal: The environment sensing unit captures external changes and generates raw signal strength SC.

[0022] Using the preset maximum voltage value VMAX, minimum voltage value VMIN and maximum resistance value RMAX, the core control node converts the original signal into digital format using the following formula: SD=SC*(VMAX-VMIN) / RMAX Assuming SC = 3.5 volts, VMAX = 5 volts, VMIN = 0 volts, RMAX = 10 ohms, the calculated digital signal strength SD is: SD = 3.5 * (5-0) / 10 = 1.75 Protective Handling Information: The converted digital signal SD is transmitted to the information encoding conversion station.

[0024] When comparing stored data with received information, a hash operation H is used, calculated as: H=SHA-512(SD||N) Here SD is the digital signal strength 1.75 calculated in the previous step, and N is a random number sequence of length 10. SHA-512 is a hashing algorithm used to ensure data integrity and security.

[0025] Activate the command execution area and calculate the verification value: If the match is successful, the access confirmation port activates the command execution area, parses and responds to the corresponding instructions.

[0026] Calculate the verification value VH using the exclusive OR operation XOR and the preset key K. The calculation method is: VH=XOR(H,K) Assume that the hash value H and the key K are two binary strings, for example, H="1010..." (assuming the length is fixed to 512 bits), K="0101..." (also 512 bits in length), then the verification value VH is the result of bitwise XOR of the two.

[0027] Through the above embodiments, the present invention demonstrates how to use a series of precise mathematical formulas and logical processes to achieve high security protection of the smart lock communication system. Specifically: The combination of the environmental perception unit and the core control node ensures the accurate capture and safe transmission of external change signals, and improves the system's ability to respond to changes in the external environment.
