[0033] The implementation details of the technical solution of this application are described in detail below:

[0034] Figure 1 FIG. 1 is a flow chart showing a communication method based on radio spectrum strength according to an embodiment of the present application. Figure 1 As shown, the communication method based on radio spectrum strength includes at least steps S110 to S150, which are described in detail as follows:

[0035] In step S110, test data is initialized, and spectrum intensity data of the wireless network is detected through the test data.

[0036] In this embodiment, the test data is initialized to simulate various conditions in a wireless network environment, and then the test data is used to detect the spectrum strength data of the wireless network, so as to evaluate and analyze the performance of the wireless network and the use of spectrum resources.

[0037] In one embodiment of the present application, the initialization test data and detecting the spectrum strength data of the wireless network through the test data include: initializing the generation of test data, transmitting the test data based on the communication path of the communicating parties, and collecting the spectrum strength data of the wireless network in real time during the transmission of the test data.

[0038] In one embodiment of the present application, diverse test data may be randomly generated, and the test data may include not only data under conventional communication scenarios, but also abnormal data and data under extreme conditions, to ensure the comprehensiveness and effectiveness of the test.

[0039] In one embodiment of the present application, a spectrum analyzer is pre-deployed on a communication path between two communicating parties to collect spectrum intensity data of the wireless network in real time during the transmission of test data.

[0040] The above process, by initializing the test data and transmitting it on the communication path, collects the spectrum strength data of the wireless network in real time, providing basic data support for the subsequent communication process. This method can ensure that the data collection is consistent with the actual application scenario, and improve the accuracy and practicality of the data.

[0041] In step S120, the spectrum intensity data is preprocessed to generate a first characteristic parameter for characterizing the spectrum intensity, an encryption key is generated based on the first characteristic parameter, and a dynamic key sequence is generated according to the encryption key.

[0042] In this embodiment, the collected spectrum intensity data is preprocessed to extract the first characteristic parameter of the current spectrum state; then, the first characteristic parameter is used as input to generate an encryption key through a specific algorithm; finally, a dynamic key sequence is generated based on the encryption key for subsequent data encryption, communication security or access control of spectrum resources, so as to ensure the security of wireless communications and efficient use of spectrum resources.

[0043] like Figure 2 As shown, in one embodiment of the present application, the spectrum intensity data is preprocessed to generate a first characteristic parameter for characterizing the spectrum intensity, an encryption key is generated based on the first characteristic parameter, and a dynamic key sequence is generated according to the encryption key, including:

[0044] S210, filtering the spectrum intensity data based on a sliding window to generate filtered data, and calculating a first characteristic parameter of the filtered data in each sliding window based on the filtered data;

[0045] S220, generating an encryption key corresponding to each sliding window based on the first characteristic parameter corresponding to each sliding window;

[0046] S230: Generate a dynamic key sequence based on the encryption keys corresponding to all the sliding windows.

[0047] In one embodiment of the present application, in the process of generating a dynamic key sequence, the spectrum intensity data is first filtered using a sliding window. Assume that the spectrum intensity data is a time series ,in t Indicates time, Indicates at time t The length of the sliding window is defined as W , then for each window i ( i =1,2,…, N ),in N is the total number of windows, and the data in the window can be expressed as , which corresponds to the generated filtered data for:

[0048]

[0049] in, W represents the length of the sliding window, Indicates at time t +1 spectral intensity, Indicates at time t The spectrum intensity, t Indicates time, i Indicates the window ID.

[0050] After generating the filtered data, the first characteristic parameter of the filtered data in each sliding window is calculated based on the filtered data. for:

[0051]

[0052] For each sliding window i , and its corresponding first characteristic parameter is , used to characterize the spectrum intensity corresponding to the current sliding window. In order to generate an encryption key, the first characteristic parameter is mapped to a fixed key space. Based on the first characteristic parameter corresponding to each sliding window, the encryption key corresponding to each sliding window is generated. for:

[0053]

[0054] in, L represents the sliding window factor, r is the encryption factor, represents the mean of the filtered data, mod M represents the M Modulo operation to ensure that the key within a fixed range.

[0055] Afterwards, the encryption keys corresponding to all sliding windows are (i=1,2,…,N) are arranged in order to generate a dynamic key sequence , used to encrypt data to be transmitted.

[0056] In the above process, the spectrum intensity data is preprocessed, the first characteristic parameter is extracted by sliding window filtering and other methods, and the encryption key and dynamic key sequence are generated based on these parameters. This method can make full use of the characteristics of the spectrum intensity data to generate an encryption key that matches the current communication environment, thereby improving the security of data transmission.

[0057] In step S130, the data to be transmitted is encrypted by using the dynamic key sequence to generate encrypted data.

[0058] In this embodiment, based on the spectrum intensity data, a second characteristic parameter that can reflect the transmission characteristics of the wireless network is first determined, and then a suitable encrypted data transmission path is selected according to the characteristic parameter to ensure secure transmission and efficient use of data in the wireless network.

[0059] In one embodiment of the present application, encrypting the data to be transmitted by using the dynamic key sequence to generate encrypted data includes:

[0060] Dividing the data to be transmitted into data blocks of preset sizes;

[0061] Each of the data blocks is encrypted based on the dynamic key sequence to generate an encrypted data block, and the encrypted data blocks are concatenated to generate encrypted data.

[0062] In one embodiment of the present application, the importance and access frequency of the data to be transmitted are obtained, and the size of the data block is determined according to the importance and access frequency of the data to be transmitted, so as to divide the data to be transmitted into data blocks. Specifically, for critical data or frequently accessed data, it can be divided into smaller data blocks for faster transmission and decryption.

[0063] Optionally, each segmented data block is marked with a data identifier, which includes information such as the sequence number, size, and checksum of the data block. These data identifiers will be used for data verification and reorganization in subsequent encryption, transmission, and decryption processes.

[0064] According to the sensitivity and transmission requirements of the data to be transmitted, one or more encryption algorithms are selected for encryption. In order to increase the encryption speed, parallel processing technology can be used. Multiple data blocks are assigned to different processor cores or threads for simultaneous encryption.

[0065] After all the data blocks are encrypted, they are concatenated into a complete encrypted data stream in their original order. During the concatenation process, data identifiers or separators are inserted to distinguish different data blocks and ensure that the data can be reassembled correctly when decrypted.

[0066] Optionally, after the splicing is completed, the encrypted data stream is verified for integrity. For example, a hash value or checksum of the data is calculated and compared with the hash value or checksum of the original data. If the verification fails, it indicates that an error occurred during the encryption or splicing process, and the encryption and splicing operations need to be performed again.

[0067] In the above process, the generated dynamic key sequence is used to encrypt the data to be transmitted, and the data is encrypted into multiple data blocks and then spliced. This method not only improves the security of data transmission, but also maintains the integrity of the data during the data transmission process to prevent the data from being tampered with or stolen.

[0068] In step S140, a second characteristic parameter for characterizing a transmission property of a wireless network is determined according to the spectrum intensity data, and a transmission path of the encrypted data is determined according to the second characteristic parameter.

[0069] In this embodiment, by analyzing the spectrum intensity data, a second characteristic parameter that can represent the current transmission characteristics of the wireless network can be identified and extracted. Subsequently, the second characteristic parameter is used as a decision basis to determine the optimal or appropriate transmission path for encrypted data in the wireless network to ensure secure data transmission and optimize network performance.

[0070] In one embodiment of the present application, determining a second characteristic parameter for characterizing a transmission property of a wireless network according to the spectrum intensity data, and determining a transmission path of the encrypted data according to the second characteristic parameter includes:

[0071] Determining, based on the spectrum intensity data, a second characteristic parameter for characterizing a transmission property of the wireless network;

[0072] Determining a fitness parameter of the wireless network according to the second characteristic parameter;

[0073] A transmission path for the encrypted data is determined according to the fitness parameter.

[0074] In an embodiment of the present application, a second characteristic parameter for characterizing the transmission property of the wireless network is determined based on the spectrum intensity data, wherein the second characteristic parameter includes the communication rate of the wireless network, the energy per bit of the network signal, and the noise power spectrum density. The above process can be directly obtained by detection and will not be described in detail here.

[0075] Determine the fitness parameter of the wireless network according to the second characteristic parameter for:

[0076]

[0077] in, θ Indicates the parameter configuration of the current wireless network. R ( θ ) represents the communication rate, Represents the energy per bit of the network signal, represents the noise power spectral density, C ( θ ) represents computational complexity or resource consumption. α , β and γ is a weight coefficient used to balance the priorities among different objectives.

[0078] After the fitness parameter is calculated, the transmission path of the encrypted data is determined according to the fitness parameter. The above process determines the second characteristic parameter according to the spectrum intensity data, and determines the fitness parameter of the wireless network based on these parameters, thereby selecting the optimal transmission path. This method can dynamically adapt to changes in the wireless network environment, ensure that data can avoid interference and congestion during transmission, and improve the efficiency and reliability of data transmission.

[0079] In one embodiment of the present application, it also includes:

[0080] Constructing a first database table based on the spectrum intensity data, the first database table including timestamps, communication frequencies corresponding to each timestamp, and strength information of network signals;

[0081] constructing a second database table based on the transmission path, wherein the second database table includes a source address, a destination address, a path identifier, and a path parameter of the transmission path;

[0082] The first database table and the second database table are associated and stored.

[0083] In this embodiment, a first database table is constructed based on the spectrum intensity data, and a second database table is constructed based on the transmission path. The first database table focuses on the spectrum intensity data, and records in detail the communication frequency and network signal intensity information at each timestamp. It is used to track and analyze the changes in the spectrum over time, which is crucial for monitoring the dynamic characteristics of the wireless communication environment.

[0084] The second database table is used to store information related to the transmission path, including the source address and destination address of the transmission path, as well as the path identifier used to uniquely identify each path and the path parameters that describe the path characteristics. By associating the two tables, not only can spectrum data and path data be managed independently, but they can also be easily linked when needed, so as to deeply analyze how spectrum conditions affect the selection and performance of transmission paths, greatly enhancing the data availability and analysis depth.

[0085] In step S150, the encrypted data is transmitted to a recipient based on the transmission path.

[0086] In one embodiment of the present application, after determining a suitable transmission path, the encrypted data is securely transmitted to the recipient via this path, ensuring that the data transmission process in the wireless network is both secure and reliable.

[0087] In one embodiment of the present application, it is also possible to: obtain real-time spectrum intensity data; and dynamically adjust the transmission path according to changes in the spectrum intensity data.

[0088] In wireless communications, it is crucial to rationally select spectrum resources to avoid signal conflicts and interference. Spectrum analysis technology can be used to analyze signals in different frequency bands and find idle or low-interference frequency bands, thereby achieving selective use of spectrum. When spectrum strength data changes, the system can dynamically adjust the transmission path based on these changes and select the frequency band with the best network quality for communication, thereby improving communication quality and reliability.

[0089] The above process obtains spectrum strength data in real time and dynamically adjusts the transmission path according to the changes in the data. This method can reflect the changes in the wireless network environment in real time, ensure that the data can always choose the best path during transmission, and further improve the efficiency and reliability of data transmission.

[0090] The technical solution of the present application is to initialize test data, detect the spectrum intensity data of the wireless network through the test data; pre-process the spectrum intensity data to generate a first characteristic parameter for characterizing the spectrum intensity, generate an encryption key based on the first characteristic parameter, and generate a dynamic key sequence according to the encryption key; encrypt the data to be transmitted through the dynamic key sequence to generate encrypted data; determine the second characteristic parameter for characterizing the transmission attribute of the wireless network according to the spectrum intensity data, and determine the transmission path of the encrypted data according to the second characteristic parameter; based on the transmission path, transmit the encrypted data to the receiver. The above process detects the spectrum intensity data of the wireless network in real time by initializing the test data, and then pre-processes the spectrum intensity data to extract the first characteristic parameter characterizing the current spectrum intensity, and generates an encryption key and a dynamic key sequence accordingly. This process not only ensures the security of data transmission, but also enhances the complexity and unpredictability of encryption by utilizing the dynamic changes of spectrum characteristics. At the same time, the second characteristic parameter determined according to the spectrum intensity data can intelligently select the optimal transmission path and optimize the data transmission efficiency. Finally, the encrypted data is securely transmitted to the receiver through the selected transmission path. The whole process not only ensures the security of communication, but also improves the efficiency and flexibility of transmission.
