[0025] To make the objectives, technical solutions, and advantages of this disclosure more apparent, exemplary embodiments according to this disclosure will now be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this disclosure, and not all embodiments of this disclosure. It should be understood that this disclosure is not limited to the exemplary embodiments described herein.

[0026] Figure 1 The flowchart illustrates an exemplary embodiment of the present disclosure of a key generation method. This method can be applied to a terminal device, which may be a server, computer, laptop, tablet, or mobile phone, etc. Figure 1 As shown, the method in this embodiment of the disclosure may include:

[0027] Step S101: In response to receiving the key generation instruction, read the pre-constructed target key cube;

[0028] The key generation instruction includes the data length of the target key to be generated, and the target key cube includes... The target key cube is divided into random number units and is divided into... Each of the subkey cubes includes a subkey cube. There are 1 random number unit, and each random number unit corresponds to a random number;

[0029] Step S102, based on the subkey cube association information, in the From each subkey cube, a random number is sequentially selected from any random number unit within the target number of subkey cubes to generate the target key;

[0030] Wherein, the subkey cube association information includes, with the Each subkey cube in the subkey cube is associated with multiple optional subkey cubes, wherein each optional subkey cube is a subkey cube that allows random number selection in the next iteration after a random number is selected in each subkey cube, and the target number is equal to the data length.

[0031] In summary, the key generation scheme method provided in this disclosure can pre-construct a target key cube containing multiple random number units and divide the target key cube into multiple sub-key cubes. This allows for the selection of random numbers from a target number of key cubes of equal length to the data during the key generation process, based on the association information between the sub-key cubes. Since each sub-key cube also contains multiple random number units, the flexibility in selecting random numbers within each sub-key cube is greater. This not only increases the number of target keys that can be generated but also enhances the randomness of the generated target keys, thereby increasing the complexity of the generated target keys.

[0032] The following are Figure 1 The specific implementation methods of each step in the illustrated embodiment are described in detail below:

[0033] In step S101, the terminal device, in response to receiving the key generation instruction, reads the pre-constructed target key cube.

[0034] In this embodiment of the disclosure, the key generation instruction includes the data length of the target key to be generated. The unit of data length can be bytes, and the specific length can be determined based on the user's actual needs. This embodiment of the disclosure does not limit this. For example, the data length can be 8 bytes or 10 bytes.

[0035] It should be noted that the target key cube includes The target key cube is divided into random number units and is divided into... Each of the subkey cubes includes a subkey cube. Each random number unit corresponds to a random number; where m and n can be specification parameters of the target key cube, which can be determined based on actual needs, and this disclosure does not limit them.

[0036] It is understandable that before receiving the key generation instruction, the terminal device can build the target key cube in advance, so that in the key acquisition scenario, the key can be generated directly based on the pre-built target key cube, thereby improving the efficiency of target key generation.

[0037] In one alternative implementation, the process of the terminal device constructing the target key cube may include: in response to receiving a key cube construction instruction, generating a key cube based on a first specification parameter in the key cube construction instruction. A random number, and according to the... m random number matrices are constructed from a set of random numbers, wherein the random number matrices include... The random number units, The random numbers in each random number unit are different, and the random numbers in the random number units at the same position in the m random number matrices are different; then, the m random number matrices are stacked to obtain an initial key cube, and based on the... A random number is used to perform a random number deduplication check on each face of the initial key cube to obtain a deduplication result; further, if the deduplication result indicates that there is a key cube face to be processed on the initial key cube, then based on the... A target random number is determined by a set of random numbers on the cube of the key to be processed, wherein the cube of the key to be processed contains the same random number, and the target random number is the [missing information]. In a random number matrix, the random numbers not included on the key cube to be processed are selected. Finally, the positions of the identical random numbers and the target random number in the target random number matrix are swapped to obtain the target key cube, wherein the target random number matrix is ​​the random number matrix containing the identical random numbers. After superimposing the constructed random number matrices into a key cube, the random numbers on each face of the key cube can be deduplicated to ensure the randomness of the random numbers in the random number units on each face of the constructed key cube, thereby ensuring the randomness of the random numbers in the random number units of each sub-key cube, further improving the randomness of the key generated based on the key cube.

[0038] It should be noted that, in this embodiment of the disclosure, the first rule parameter is a random number parameter, and the random number matrix specification parameter is m. Specifically, the first rule parameter can be determined based on actual needs, and this embodiment of the disclosure does not limit it; wherein, the terminal device can generate based on the first specification parameter. A random number, and according to the... The first specification parameter m can be used to construct m random number matrices. Specifically, the value of m can be determined based on actual needs, and this embodiment does not limit this. The number of bits in the random numbers can also be determined based on actual needs, and this embodiment does not limit this.

[0039] For example, assuming the first rule parameter is 16, the terminal device can generate 256 random numbers, and construct 16 rules based on these 256 random numbers. A random number matrix of specified size (containing 256 random number units), where random numbers can range from 0x00 to 0xFF; for example... Figure 2 As shown, Figure 2 An embodiment of this disclosure is shown. A random number matrix of specified specifications.

[0040] It is understood that, in the embodiments of this disclosure, the terminal device is based on the... The process of constructing an m random number matrix from a set of random numbers may include: repeating the process m times... A random number is randomly filled into... The process of generating m initial random number matrices is as follows: During the generation of the m random number matrices, the terminal device needs to ensure that the random numbers in the random number cells at the same position in the m random number matrices are different.

[0041] Another example is the initial key cube constructed by the terminal device based on the first rule parameter 16, such as... Figure 3 As shown, the initial key cube consists of 16... The random number matrix A1-A16 of the specified standard are superimposed to generate the key cube. If there are identical random numbers on the surface along the negative y-axis, assuming that the identical random numbers are random numbers x in the random number units of random number matrix A2 and random number matrix A12, and the target random number is determined to be y based on 256 random numbers, then the random numbers y and x in random number matrix A2 can be swapped; or, the random numbers y and x in random number matrix A12 can be swapped to obtain the target key cube.

[0042] In one optional implementation, after constructing the target key cube, the terminal device may further: divide the target key cube into segments based on the second specification parameter in the key cube construction instruction. Each subkey cube is first identified; then, subkey cubes adjacent to each subkey cube in terms of points, lines, and faces are determined, resulting in multiple optional subkey cubes associated with each subkey cube; finally, these are combined with... Each subkey cube is associated with multiple optional subkey cubes, yielding subkey cube association information. After constructing the target key cube, it can be divided into multiple subkey cubes. By utilizing the adjacency relationships between subkey cubes based on points, lines, and surfaces, the optional subkey cubes that can be used for random number selection in each subkey cube can be determined. This subkey cube association information facilitates rapid key cube generation during the key generation process.

[0043] It should be noted that in the embodiments of this disclosure, the second specification parameter is the partitioning specification parameter of the subkey cube. The second specification parameter can be n, and specifically, it can be determined based on actual needs. This embodiment of the disclosure does not limit this.

[0044] Based on the adjacency relationship between the surfaces of the subkey cubes and other subkey cubes, the multiple subkey cubes can be divided into a first subkey cube and a second subkey cube. Each face of the first subkey cube has an adjacent subkey cube, while at least one face of the second subkey cube does not have an adjacent subkey cube. The multiple optional subkey cubes associated with the first subkey cube include 26, while the multiple optional subkey cubes associated with the second subkey cube include 17.

[0045] For example, if the second specification parameter is 3, then the target key cube is divided into... Subkey cube, such as Figure 4 As shown, Figure 4 It shows a segmented into A schematic diagram of the target key cube of the sub-key cubes.

[0046] In one alternative implementation, the terminal device may read a pre-built target key cube in response to receiving a key generation instruction.

[0047] In step S102, the terminal device, based on the subkey cube association information, in the... From each of the subkey cubes, a random number is selected from any random number unit within the target number of subkey cubes to generate the target key.

[0048] In this embodiment of the disclosure, the subkey cube association information includes, with the Each subkey cube in the subkey cube is associated with multiple optional subkey cubes, wherein the optional subkey cubes are subkey cubes that allow random number generation in the next iteration after a random number is selected in each subkey cube.

[0049] Understandably, if the selected subkey cube is the first subkey cube, then the number of optional subkey cubes associated with the first subkey cube includes 26; if the selected subkey cube is the second subkey cube, then the number of optional subkey cubes associated with the second subkey cube includes 17.

[0050] In one alternative implementation, the terminal device, based on the subkey cube association information, in the... The process of generating the target key by sequentially selecting random numbers from any random number unit within the target number of subkey cubes in the subkey cubes includes: in the... Select any one of the subkey cubes to obtain the target subkey cube. Next, select a random number from any random number unit within the target subkey cube to obtain the random numbers to be combined. Then, query the subkey cube association information for multiple optional subkey cubes associated with the target subkey cube. Further, determine any one of the multiple optional subkey cubes associated with the target subkey cube as the updated target subkey cube, and repeat the above process by selecting a random number from any random number unit within the target subkey cube to obtain the random numbers to be combined, until the target number of random numbers to be combined are selected from the target number of subkey cubes. Finally, combine the target number of random numbers to be combined to obtain the target key. Based on the subkey cube association information, a target number of random numbers can be selected from multiple subkey cubes with a target number of subkey cubes of equal data length to generate the target key, ensuring the randomness and reliability of the generated key.

[0051] In one optional implementation, the process by which the terminal device combines the target number of random numbers to be combined to obtain the target key may include: combining the target number of random numbers to be combined in a random order to obtain the target key. The target number of random numbers to be combined, which are selected to be the same length as the data, can be randomly combined to further enhance the randomness of the obtained target key.

[0052] In one optional implementation, the process by which the terminal device combines the target number of random numbers to be combined to obtain the target key may include: combining the target number of random numbers to be combined in the order in which they were selected to obtain the target key.

[0053] For example, with the first rule parameter being 16, and the target key cube being divided into... In the case of multiple subkey cubes, if the data length is 8 bytes, and since the target key cube contains 4096 random number units, and there are 26 or 17 optional subkey cubes associated with each subkey cube, the terminal device can generate w keys, where...

[0054] ;

[0055] As can be seen, the target key cube can generate at least 28 trillion and at most 855 trillion keys for terminal devices, which greatly increases the number of keys that can be generated.

[0056] In an optional implementation, the terminal device may further: in response to receiving a key cube update instruction, construct an updated target key cube based on the updated first specification parameter and the updated second specification parameter in the key cube construction instruction, and determine the updated sub-key cube association information, wherein the updated first specification parameter is greater than the original first specification parameter, and the updated second specification parameter is greater than the original second specification parameter. If the number of keys that can be generated from the constructed target key cube still cannot meet the requirement for the number of random keys, it may be considered to increase the parameters used to construct the key cube and the parameters used to divide the key cube to construct a target key cube that can generate more keys for the terminal device.
