[0039] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0040] As an example, with the development of network data transmission, big data analysis and other technologies, how to ensure the security of data has become an important demand for protecting user privacy, enterprise trade secrets and the like. In the traditional data security protection process, the traditional algorithm used is too monotonous and is rarely maintained, and the same key is often used for a long time to encrypt data, which leads to the key being easily cracked, and in turn leads to data leakage, seriously affecting user privacy and enterprise trade secrets.

[0041] To this end, one of the core points of the application is to construct a key generation system that cooperates with the natural environment, reasonably utilize the physical conditions formed in nature, obtain corresponding biological signals through the richness and randomness of nature, and generate corresponding keys based on the biological signals, thereby achieving more secure, random and convenient key generation. Specifically, the application can be applied to a key generation system, which can include a data processing device, a data acquisition device connected to the data processing device, and a plurality of sonar collection sensors connected to the data acquisition device. Each sonar collection sensor is located at a different ocean depth and is used to collect sonar from organisms in the corresponding ocean area. In the process of generating a key, the sonar collection sensor can obtain a data collection signal sent by the data acquisition device and collect sonar information corresponding to the organisms in the ocean area based on the data collection signal. The sonar information includes at least the audio frequency of different organisms at different ocean depths and the collection timestamp, which is used to mark the current collection operation. Then, the data acquisition device can obtain the sonar information collected by each sonar collection sensor at the same time point, mix the audio frequency according to the audio frequency, and obtain an audio array corresponding to different organisms in different ocean areas. The audio array includes the audio frequency and the audio wavelength of each organism. Then, a key generation formula is obtained, and the audio array is substituted into the key generation formula to obtain a sequence corresponding to the sonar information. The sequence is randomly taken, and a dynamic key for data encryption is generated. The data processing device is used to perform corresponding data encryption operations according to the dynamic key, thereby ensuring the richness and uncertainty of data collection through the sonar collection sensors at different ocean depths, generating a key based on these data, making the generated key more random, and improving the security of the key. On the other hand, the sonar information corresponding to different ocean areas is mixed and summarized, and a corresponding key is generated through the key generation formula, further increasing the complexity of the key and improving the security of data encryption based on the key.

[0042] Reference Figure 1 , a structure block diagram of a key generation system provided in an embodiment of the application is shown, which can specifically include a data processing device, a data acquisition device connected to the data processing device, and a plurality of sonar collection sensors connected to the data acquisition device. Each sonar collection sensor is located at a different ocean depth and is used to collect sonar from organisms in the corresponding ocean area. Wherein,

[0043] The sonar collection sensor is used for acquiring a data collection signal sent by the data collection device, and collecting sonar information corresponding to organisms in the marine area based on the data collection signal, wherein the sonar information at least includes audio frequencies of different organisms located in different marine depths and a collection timestamp, and the collection timestamp is used for marking the current collection operation;

[0044] The data collection device is used for acquiring the sonar information collected by each sonar collection sensor at the same time point, mixing the audio frequencies according to the audio frequencies, obtaining an audio array corresponding to different organisms located in different marine areas, and the audio array includes the audio frequencies and audio wavelengths of each organism; then a key generation formula is acquired, the audio array is substituted into the key generation formula, a number sequence corresponding to the sonar information is obtained, and a dynamic key used for data encryption is generated by randomly taking positions of the number sequence;

[0045] The data processing device is used for performing corresponding data encryption operation according to the dynamic key.

[0046] Optionally, the data processing device can be a mobile terminal, a PC terminal, a server or the like, and can be used for performing corresponding data processing operation, such as data storage and data transmission; the data collection device can be used for generating a corresponding key according to an organism signal; and different sonar collection sensors can be located in different marine depths, and are used for collecting sonar information of organisms in a marine area in a preset range of the marine depth. Figure 2 In an example, FIG. 1 shows a setting schematic diagram of a sonar collection sensor provided in an embodiment of the present application, and the sonar collection sensor is deployed in a marine area. For the sonar collection sensor, corresponding sonar collection sensors can be respectively deployed in different marine depths, for example, can be deployed in a marine depth of 500 meters, 1000 meters or the like away from a horizontal plane, and sonar information of organisms near the depth is collected, including sonar information of corresponding fish, so as to reasonably utilize physical generation conditions in nature, and the diversity of source data generation is ensured by the richness of marine organisms (audio frequencies of different species are greatly different), and the security of a subsequently generated key is fundamentally ensured, and marine ecological environments of each depth of the marine are different, audio of multiple environments is listened to and collected, the generation process is difficult to be copied, and the periodic maintenance of the key in the system can be met due to the richness of marine species.

[0047] It should be noted that the data processing device can also be a software program that can run on the data acquisition device to control the data acquisition device to send corresponding data acquisition signals to each sonar collection sensor through the data acquisition device, and obtain sonar information collected by each sonar collection sensor, and the like, and the present application does not limit this.

[0048] In the embodiment of the present application, when the user needs to encrypt the data on the data processing device by performing corresponding operations, the data processing device can respond to the user operation and generate a corresponding data acquisition instruction, and then send the data acquisition instruction to the data acquisition device, so that the data acquisition device converts the data acquisition instruction into a corresponding data acquisition signal, and sends the data acquisition signal to each sonar collection sensor located at different ocean depths, so as to collect corresponding sonar information through the sonar collection sensor. Optionally, for the encryption required scene, it can include data transmission, data storage, digital signature, permission token generation, and the like, and the present application does not limit this.

[0049] In a specific implementation, each sonar collection sensor can perform a corresponding information collection operation at the same time point after receiving the data acquisition signal, so as to collect the audio frequency corresponding to the sound emitted by different organisms at different ocean depths at the same time point through different sonar collection sensors and the corresponding collection timestamp. Wherein, for the collection timestamp, it can be used to mark the current collection operation, and at the same time, the collection timestamp can be associated with the subsequently generated key. On the one hand, the key is generated by collecting corresponding sonar information, which not only ensures the diversity and security of the source data generation, but also ensures the randomness of the key generation. On the other hand, the key is marked by the collection timestamp, which ensures the uniqueness of the key and facilitates subsequent data tracing.

[0050] After the multiple sonar collection sensors collect the sonar information of the organisms in different layers of sea areas at the same time point, the collected sonar information can be transmitted to the data acquisition device. The data acquisition device can effectively extract the data of the sonar information to obtain the audio frequency of the sound emitted by different organisms at different ocean depths and the collection timestamp, and then mix the sound frequency according to the audio frequency to obtain the corresponding audio array of different organisms in different sea areas.

[0051] Specifically, the data acquisition device can obtain audio sound waves, and calculate the audio wavelengths corresponding to the sound emitted by each organism by using the audio hertz corresponding to each organism and the audio sound waves. Then, the audio hertz and the audio wavelengths corresponding to each organism are sequentially stored in an array to obtain an audio array corresponding to different organisms in different sea areas. Thus, a set of audio arrays containing different organisms in each sea area can be obtained through the above process, improving the complexity and uncertainty of the data, further improving the security of the initial data, and the audio arrays collected in different deep sea areas do not need to be disposed separately. For example, {x1, y1; x2, y2; x3, y3; …; x N , y N}, the former of each set of values can be audio hertz, and the latter can be audio wavelength.

[0052] When the data acquisition device generates the corresponding audio array, a key generation formula for generating a key can be further obtained, and the audio array is substituted into the key generation formula to obtain a sequence corresponding to the sonar information, and the sequence is randomly taken to generate a dynamic key for data encryption. Thus, on the one hand, the sonar information corresponding to organisms located at different ocean depths is obtained by the sonar collection sensor located at different ocean depths, which ensures the richness and uncertainty of data collection. The generation of the key based on these data makes the generated key more random, improving the security of the key. On the other hand, the sonar information corresponding to different ocean regions is mixed and processed, and the corresponding key is generated by the key generation formula, further increasing the complexity of the key and improving the security of the data encryption based on the key.

[0053] In an optional embodiment, the data acquisition device can substitute the audio hertz and the audio wavelengths corresponding to each organism into the following key generation formula to obtain a sequence corresponding to the sonar information:

[0054] ×cos(y1)+ ×cos(y2)+ ×cos(y3)+…+ ×cos(y N )=α,

[0055] wherein x n represents audio hertz, and y n represents audio wavelength.

[0056] After the corresponding sequence is obtained through the above process, the data acquisition device can generate a dynamic key for data encryption based on the sequence by randomly taking bits. Specifically, the data acquisition device can obtain a key length corresponding to the data acquisition instruction; randomly take bits from the sequence using the key length to obtain a random sequence corresponding to the key length and used for data encryption, and then send the dynamic key to the data processing device, so that the data processing device can perform corresponding data encryption operations based on the dynamic key, thereby constructing a key generation system that cooperates with the natural environment, reasonably utilizing the physical conditions in nature, obtaining corresponding biological signals through the richness and randomness of nature, and generating a corresponding key based on the biological signals to achieve a more secure, random and convenient key generation.

[0057] In the embodiments of the present application, the key generation system can be applied, which can include a data processing device, a data acquisition device connected to the data processing device, and a plurality of sonar collection sensors connected to the data acquisition device, each sonar collection sensor being located at a different ocean depth for collecting sonar of organisms in the corresponding ocean area. In the process of generating a key, the sonar collection sensor can obtain a data acquisition signal sent by the data acquisition device and collect sonar information corresponding to the organisms in the ocean area based on the data acquisition signal. The sonar information at least includes the audio frequency of the sound emitted by different organisms at different ocean depths and the collection timestamp, which is used to mark the current collection operation. Then the data acquisition device can obtain the sonar information collected by each sonar collection sensor at the same time point, and mix the sound frequency according to the audio frequency to obtain an audio array corresponding to different organisms in different ocean areas, the audio array including the audio frequency and the audio wavelength of each organism. Then the key generation formula is obtained, and the audio array is substituted into the key generation formula to obtain a sequence corresponding to the sonar information, and the sequence is randomly taken to generate a dynamic key for data encryption. The data processing device is used to perform corresponding data encryption operations according to the dynamic key, so that on the one hand, the sonar collection sensors located at different ocean depths obtain the sonar information corresponding to the organisms located at different ocean depths, ensuring the richness and uncertainty of data collection, and the key is generated based on these data, making the generated key more random and improving the security of the key. On the other hand, the sonar information corresponding to different ocean areas is mixed and summarized, and the corresponding key is generated through the key generation formula, further increasing the complexity of the key and improving the security of the data encryption based on the key.

[0058] In order for those skilled in the art to better understand the technical solutions in the embodiments of the present application, the following will be exemplarily described by an example:

[0059] Referring to Figure 3 , a flowchart of key generation provided in an embodiment of the application is shown, which can specifically include: when a data processing device needs to maintain operation, it can actively request a data collection device to obtain a corresponding key, the data collection device can generate a key through periodic sonar data on one hand, and can also send a corresponding data collection signal to each sonar collection sensor in real time to collect real-time sonar information. Specifically, each sonar collection sensor can collect sound frequency of organisms in the sea area to which it belongs at the same time point, and determine the corresponding audio wavelength and audio hertz based on the sound frequency, and then the data collection device can further merge the audio arrays of different sea areas to obtain an audio array in which audio hertz and audio wavelength are stored, and then substitute the audio array into the following formula to obtain a corresponding sequence:

[0060] ×cos(y1)+ ×cos(y2)+ ×cos(y3)+…+ ×cos(y N )=α

[0061] After obtaining the sequence through the above process, the sequence can be randomly taken to generate a corresponding dynamic key, and then the dynamic key can be returned to the data processing device so that it can complete corresponding data encryption operation.

[0062] Referring to Figure 4 , a step flowchart of a dynamic key generation method provided in an embodiment of the application is shown, which is applied to a data collection device including sonar collection sensors located at different sea depths, and can specifically include the following steps:

[0073] Wherein, x n is used to represent the audio hertz, y n is used to represent the audio wavelength.

The sonar information at least includes the audio frequency of the sound emitted by different organisms at different ocean depths and the collection timestamp, which is used to mark the current collection operation. Then the data acquisition device can obtain the sonar information collected by each sonar acquisition sensor at the same time point, and mix the sound frequency according to the audio frequency, to obtain an audio array corresponding to different organisms in different ocean areas, which includes the audio frequency and the audio wavelength of each organism. Then the key generation formula is obtained, and the audio array is substituted into the key generation formula to obtain a sequence corresponding to the sonar information, and the sequence is randomly taken to generate a dynamic key for data encryption. The data processing device is used to perform corresponding data encryption operation according to the dynamic key, so as to obtain the sonar information corresponding to the organisms at different ocean depths through the sonar acquisition sensors at different ocean depths, which ensures the richness and uncertainty of data acquisition. The key is generated based on these data, so that the generated key is more random, and the security of the key is improved. On the other hand, the sonar information corresponding to different ocean areas is mixed and summarized, and the corresponding key is generated through the key generation formula, which further increases the complexity of the key and improves the security of the data encryption based on the key.
