[0054] Specific details are provided in the following description to provide a complete understanding of the exemplary embodiments.

For example, apparatus may be shown in block diagrams to avoid obscuring the examples with unnecessary details.

[0055] Example 1:

[0056] This embodiment provides a method for encrypted data transmission to a robot cloud, which can be applied to corresponding robot data processing terminals, such as... Figure 1 As shown, the method includes the following steps:

[0057] S1. During robot operation, collect robot sensor data and the corresponding sensor numbers in real time, and obtain the robot number.

[0058] In practice, during the operation of the robot, the processing terminal can collect relevant robot sensor data in real time, determine the sensor number corresponding to the robot sensor data, and retrieve the robot number for subsequent processing.

[0059] S2. Retrieve the pre-stored numerical mapping table and perform data mapping processing on the robot sensing data based on the numerical mapping table to obtain the sensing mapping data corresponding to the robot sensing data.

[0060] In practice, the processing terminal retrieves a pre-stored numerical mapping table locally. This table contains several numbers and their associated mapping numbers. Then, each digit of the robot's sensor data is substituted into the numerical mapping table to perform numerical mapping, obtaining the associated mapping numbers for each digit. Finally, these associated mapping numbers are combined according to the order of the digits to obtain the corresponding sensor mapping data for the robot's sensor data.

[0061] S3. Generate a conversion factor using the sensor number, and use the conversion factor to perform data conversion processing on the sensor mapping data to obtain the corresponding sensor transformation data.

[0062] In practice, the processing terminal first performs a hash calculation on the sensor number to obtain a first hash value, and then performs a base conversion (such as decimal conversion) on the first hash value to obtain the number conversion data H. Then, it uses the number conversion data H to calculate the conversion factor S, S = H mod M, where mod represents the modulo operation, and M is a set prime number. Next, it calculates the absolute value of the difference between each digit in the sensor mapping data and the conversion factor S, and combines these absolute values ​​according to the order of the digits in the sensor mapping data to obtain the sensor transformation data.

[0063] S4. Generate a counting query code using the robot number and sensor number, retrieve the counting table corresponding to the counting query code, and determine the accumulated count value based on the counting table.

[0064] In practice, the processing terminal first combines the robot number and sensor number to obtain a combined number, and then performs a hash calculation on the combined number to obtain a second hash value, which is used as the counting query code. Next, it searches the local counting table associated with the counting query code. If a corresponding counting table is found, it retrieves that table, determines the last count value recorded in the table, and increments the last count value by 1 to obtain the accumulated count value. Finally, the accumulated count value is updated and recorded at the end of the counting table to obtain the updated counting table. The updated counting table is then associated with the corresponding counting query code and archived for use in the next counting cycle.

[0065] S5. Generate a dynamic key using the robot ID, sensor ID, and accumulated count value.

[0066] In practice, the processing terminal combines the robot number, sensor number, and accumulated count value to obtain a dynamically combined data string. Then, it uses the SHA-256 algorithm to calculate a dynamic key from this dynamically combined data string. By adding a dynamic key, key cracking can be effectively prevented, thus improving the security of data transmission.

[0067] S6. Use a dynamic key to encrypt the sensor transformation data to obtain the corresponding encrypted sensor data, and encapsulate the encrypted sensor data, robot number, and sensor number to obtain the corresponding robot data packet.

[0068] In practice, the processing terminal can use the AES-GCM (a symmetric encryption algorithm combining encryption and authentication functions, widely used in security protocols such as TLS and IPsec) encryption algorithm based on a dynamic key to encrypt the sensor transformation data, obtaining the corresponding encrypted sensor data. Then, the processing terminal generates a random pseudocode, which consists of several distinct pseudocode digits. It finds the pseudocode digits corresponding to each digit of the robot number in the random pseudocode, and combines the digits of these pseudocode digits in the random pseudocode according to the order of the digits in the robot number to obtain the first encrypted number. Similarly, it finds the pseudocode digits corresponding to each digit of the sensor number in the random pseudocode, and combines the digits of these pseudocode digits in the random pseudocode according to the order of the digits in the sensor number to obtain the second encrypted number. Finally, the processing terminal encapsulates the encrypted sensor data into a data packet, encapsulating the first and second encrypted numbers in the packet header and the random pseudocode in the packet tail, obtaining the robot data packet.

[0069] S7. Upload the robot data packet to the cloud server so that the cloud server can receive the robot data packet, parse the robot data packet, obtain the sensor encryption data, robot number and sensor number, and use the robot number and sensor number to reverse process the sensor encryption data to obtain the robot sensor data.

[0070] In practice, after receiving the robot data packet, the processing terminal uploads it to the cloud server. Upon receiving the robot data packet, the cloud server first parses it to obtain the encrypted sensor data, robot ID, and sensor ID. Then, it generates a counting query code using the robot ID and sensor ID, retrieves the corresponding counting table from the database, and determines the accumulated count value based on the counting table. Next, it generates a dynamic key using the robot ID, sensor ID, and accumulated count value, and uses this dynamic key to decrypt the encrypted sensor data, obtaining the sensor transformation data. Then, it generates a conversion factor using the sensor ID and uses this conversion factor to perform a data inverse conversion on the sensor transformation data, obtaining sensor mapping data. Finally, it retrieves the corresponding robot's numerical mapping table from the database based on the robot ID and performs a reverse data mapping on the sensor mapping data based on the numerical mapping table, obtaining the corresponding robot sensor data.

[0071] This method achieves dual protection for robot data by performing data transformation and dynamic encryption on the robot's raw data. It effectively enhances the confidentiality and anti-analysis capabilities of the robot's cloud-based data, preventing data from being maliciously cracked or tampered with. Moreover, the dual protection process only uses two built-in identification information: robot number and sensor number, without introducing unnecessary external parameters and tools, ensuring the purity of the processed and transmitted data as well as the efficiency of data protection processing and transmission.
