[0043] The following is combined with Figure 1 The present invention is further described in detail:

[0044] Example 1

[0045] See attached Figure 1As shown, a secure and efficient communication method and system based on an edge server includes the following steps:

[0046] S1: Create edge server processing nodes and classify the edge server processing nodes;

[0047] S2: The terminal device collects or generates data, and processes, classifies and grades the collected or generated data;

[0048] S3: sending the classified, graded and processed data to the corresponding edge server processing nodes according to the type and level, and the edge server processing nodes process the acquired data according to the data type and corresponding requirements;

[0049] S4: deploying a chaos system in the edge server, generating an encryption key through the chaos system, encrypting the data processed according to the data type and corresponding requirements based on the encryption key, and transmitting the encrypted data to the terminal device, and encrypting the encryption key according to the specified rules and transmitting it to the terminal device;

[0050] S5: The encrypted encryption key is reversely processed according to a specified rule to generate a decryption key, and the received encrypted data is decrypted based on the decryption key.

[0051] During the communication process, an edge server processing node is first created near the terminal device, and the edge server processing node is classified by type and level according to the terminal device data. Then the terminal device collects data or generates data in real time, and performs denoising on the collected or generated data. The data is then classified according to the type, and each category of data is graded according to the divided categories. The classified and graded data is then sent to the corresponding edge server processing node according to the type and level. Finally, the server node processes the acquired data and transmits or feeds back the processed data.

[0052] The above communication processing process does not require long-distance data transmission, and is processed by an edge server processing node that is closer to the terminal device. On the one hand, it effectively reduces the data transmission distance, improves data communication efficiency, and improves the security of data transmission; on the other hand, by classifying and grading the edge server processing nodes and data, and using the corresponding edge server processing nodes to process the corresponding data, the data processing efficiency is further improved. In the edge server, the specified characters in the encryption key string generated by the chaotic system are scrambled according to the specified scrambling algorithm, the encrypted key string after scrambling is scrambled according to the specified scrambling algorithm, and the encrypted key string after scrambling is reversed by the reverse slicing algorithm. After the data is encrypted by the encryption key, the encryption key string is combined with the scrambling, scrambling and reverse processing, and transmitted to the terminal device for reverse processing, reverse scrambling and reverse scrambling to obtain the decryption key, which further improves the security of the edge data communication process.

[0053] In step S1, the following specific steps are included:

[0054] S11: deploy edge server processing nodes and establish communication interconnection between the edge server processing nodes and terminal devices;

[0055] S12: The edge server processing nodes are classified into categories, and the classification is based on the types of data generated and collected by the terminal devices.

[0056] In step S12, the types of edge server processing nodes are divided into structured processing nodes and unstructured processing nodes. In step S11, the edge server processing node is arranged at a position relatively close to the terminal device, and then a communication interconnection is established between the edge server processing node and the terminal device, so that the data at the terminal device end can be transmitted to the edge server processing node for the edge server processing node to process the data.

[0057] In step S12, the types of edge server processing nodes are divided, which may include being divided into structured data processing nodes and unstructured data processing nodes. Since structured data is organized and can be accessed and processed through a database or other structured methods, and unstructured data has no fixed format and requires special methods for management and processing, the server is divided into structured data processing nodes and unstructured data processing nodes, and different data are processed in a targeted manner through different servers, so that data processing is more professional and efficient.

[0058] Example 2

[0059] Based on Example 1, processing the collected or generated data in step S2 includes the following specific processes:

[0060] S21: De-noising, compressing and integrating the collected or generated data.

[0061] S22: classify the denoised, compressed and integrated data into types, including structured data and unstructured data;

[0062] S23: Classify the structured data and classify the unstructured data into levels, where the levels at least include a first priority, a second priority, and a third priority.

[0063] In the above solution, in steps S22 and S23, the categories of the collected and generated data are divided to match the category division of the edge server processing nodes in step S1.

[0064] The data collected or generated in the terminal device will contain some noise data. Therefore, before transmitting the data to the terminal device, the noise in the data is first removed to reduce unnecessary data transmission, reduce the amount of data transmission, improve transmission efficiency, and reduce the amount of data processing. The denoised data is compressed and integrated to further increase the data transmission efficiency and reduce the possibility of data transmission congestion.

[0065] Since structured data is organized and can be accessed and processed through databases or other structured methods, while unstructured data has no fixed format and requires special methods to manage and process. Therefore, the data collected or generated at the terminal device is classified into structured data and unstructured data, and then the structured data and unstructured data are transmitted to the structured data processing node or unstructured processing respectively, and the structured data processing node or unstructured data is processed in a targeted manner to improve the data processing efficiency and the accuracy of data processing.

[0066] The structured data is classified into levels, and the unstructured data is classified into levels, and the levels of the classification include at least the first priority, the second priority and the third priority. By setting different priorities for the data, the important data is processed first, and the less important or unimportant data is processed later, so that the important data can be transmitted and processed in time, ensuring the timely priority processing of the important data.

[0067] Example 3

[0068] See also Figure 3 Based on Example 1 or Example 2, step S4 also includes an encryption key string encryption process, which is as follows:

[0069] S41: scrambling the specified characters in the encryption key character string generated by the chaotic system according to a specified scrambling algorithm;

[0070] S42: shuffling the encrypted key string after scrambling according to a specified shuffling algorithm;

[0071] S43: The encrypted key character string after the random processing is reversed by using a reverse slicing algorithm.

[0072] By scrambling the encryption key string based on the specified characters, replacing the specified characters with other characters, and then scrambling them through the scrambling algorithm, all the characters in the scrambled key string are scrambled according to the specified rules. At this time, even if the intruder steals the relevant data, he will not be able to know the key string because he does not know the scrambling and scrambling rules, which greatly improves the security of data communication. The security of the key transmission process is further improved by reversing the order.

[0073] The decryption process in step S5 also includes the following process:

[0074] S51: The encrypted key character string after the reverse processing is reversed again according to the reverse slicing algorithm;

[0075] S52: performing reverse shuffling of the encrypted key character string after the re-reversal processing based on a specified shuffling processing algorithm;

[0076] S53: Perform reverse scrambling on the designated characters of the reverse scrambled encryption key character string according to a designated scrambling algorithm to obtain a decryption key character string.

[0077] In the edge server, the specified characters in the encryption key string generated by the chaotic system are scrambled according to the specified scrambling algorithm, the encrypted key string after scrambling is scrambled according to the specified scrambling algorithm, and the encrypted key string after scrambling is reversed by the reverse slicing algorithm. After the data is encrypted by the encryption key, the encryption key string is scrambled, scrambled and reversed, and transmitted to the terminal device for reverse processing, reverse scrambling and reverse scrambling to obtain the decryption key, which further improves the security of the edge data communication process.

[0078] In step S5, after processing the acquired data, the edge server processing node stores the processed data or feeds the data back to the corresponding terminal device.

[0079] See also Figure 2, a secure and efficient data communication system based on an edge server, used to implement any of the above-mentioned secure and efficient communication methods based on an edge server, including a data classification module, a data grading module, a data transmission module, a data processing module and an edge server processing node, wherein the data classification module, the data grading module and the data transmission module are connected to a terminal device, and the data processing module is arranged on the edge server processing node.

[0080] The data classification module is used to classify the data collected or generated by the terminal device, and the classification includes structured data and unstructured data; the data classification module is used to classify the classified data, and the classification includes the first priority, the second priority and the third priority. The priority represents the priority of data processing. When the data of the first priority, the second priority and the third priority exist at the same time, the data of the first priority is processed first, the data of the second priority is processed secondly, and the data of the third priority is processed last. The data priority can also be adjusted according to the specific situation and can be divided into more levels of priority. The data transmission module is used to transmit the classified and graded data to the edge server processing node for processing. The data transmission module will transmit according to the priority of the data. The data with a high priority will be transmitted first, that is, the data of the first priority is transmitted first, the data of the second priority is transmitted secondly, and the data of the third priority is transmitted last. The data processing module is used to process the acquired data.

[0081] The secure and efficient data communication system based on the edge server also includes a cache module set at the edge server processing node end, the cache module is used to store temporary processing data, and also includes a path selection module, the path selection module is connected to the terminal device, and is used to select a transmission path for the data collected and generated by the terminal device after classification and grading.

[0082] In summary, the secure and efficient communication method and system based on the edge server provided by the present invention first creates an edge server processing node, and divides the edge server processing nodes into types and levels; then the terminal device collects data or generates data; then the collected or generated data is processed, classified and graded; and the classified, graded and processed data are sent to the corresponding edge server processing node according to the type and level; finally, the edge server processing node processes the acquired data. This communication processing process does not require long-distance data transmission, and is processed by an edge server processing node that is closer to the terminal device, which greatly reduces the data transmission distance, improves data communication efficiency, and improves the security of data transmission; and by classifying and grading the edge server processing nodes and data, using the corresponding edge server processing nodes to process the corresponding data, the data processing efficiency is further improved.

[0083] In the edge server, the specified characters in the encryption key string generated by the chaotic system are scrambled according to the specified scrambling algorithm, the encrypted key string after scrambling is scrambled according to the specified scrambling algorithm, and the encrypted key string after scrambling is reversed by the reverse slicing algorithm. After the data is encrypted by the encryption key, the encryption key string is scrambled, scrambled and reversed, and transmitted to the terminal device for reverse processing, reverse scrambling and reverse scrambling to obtain the decryption key, which further improves the security of the edge data communication process.
