[0055] Figure 5 This is a block diagram illustrating an apparatus for generating random numbers according to an exemplary embodiment. Detailed Implementation

[0056] To enable those skilled in the art to better understand the technical solutions of this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings.

[0057] It should be noted that the terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this disclosure are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this disclosure described herein can be implemented in orders other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0058] Figure 1 This is a flowchart illustrating a random number generation method according to an exemplary embodiment, such as... Figure 1 As shown, the random number generation method includes the following steps.

[0059] In step S11, multiple sets of solar spectral information are acquired, and each set of solar spectral information includes band spectral information of multiple spectral bands.

[0060] In many scenarios, random numbers are required. For example, when two programs interact, random numbers can be appended to the serial number to ensure the uniqueness of the request serial number. Alternatively, random numbers can be used to update the parameter keys in file encryption / decryption or system interaction scenarios to ensure data security. In addition, when persisting data, random numbers can be added to the append to obtain the primary key identifier, which greatly ensures the uniqueness of the primary key.

[0061] In this disclosure, random numbers can be generated based on solar spectral information. Since solar spectral information is constantly changing, the generation of random numbers is more random and uncertain. The solar spectrum can be divided into visible and invisible light. Visible light, after scattering, is divided into seven colors: red, orange, yellow, green, cyan, blue, and violet. Each color of visible light corresponds to a different wavelength band, with red light having a longer wavelength, orange light having a shorter wavelength than red light, and so on, with violet light having the shortest wavelength. Invisible light is divided into two types: infrared light, which has a longer wavelength than red light, and ultraviolet light, which has a shorter wavelength than violet light. The solar spectral information used in this application may include the spectral information of all the above-mentioned bands, or the spectral information of several of them; no specific limitation is made.

[0062] In this step, multiple sets of solar spectral information can be obtained. The solar spectral information includes band spectral information of multiple bands. The band spectral information can refer to the sum or average value of the irradiance values ​​of each wavelength in the corresponding band, or the irradiance value of the median wavelength in the corresponding band, or the maximum, minimum or median value of the irradiance values ​​of each wavelength in the corresponding band. In addition, it can refer to the wavelength with the largest irradiance value in the corresponding band. The specific details are not limited.

[0063] In one implementation, the step of acquiring multiple sets of solar spectral information may include: randomly determining multiple locations and the corresponding time point for each location; and collecting solar spectral information for each location at the corresponding time point. In other words, based on the randomly determined locations and time points, the solar spectral information for that location at that time point is collected. Thus, due to the randomness of the locations and time points, the randomness of the collected solar spectral information is greater, and the randomness of the subsequently obtained random numbers is also greater.

[0064] In step S12, the intermediate value corresponding to each group of solar spectral information is determined based on the included band spectral information.

[0065] After acquiring solar spectral information, for each set of solar spectral information, an intermediate value can be determined based on the spectral information of the included bands. Specifically, the minimum, average, or maximum value of the included bands can be taken, or a preset algorithm can be used to calculate the intermediate value from the included bands.

[0066] In one implementation, each set of solar spectral information includes spectral information from nine bands: the first band, the second band, the third band, the fourth band, the fifth band, the sixth band, the seventh band, the eighth band, and the ninth band. The step of determining the intermediate value corresponding to each set of solar spectral information based on the included spectral bands can include:

[0067] For any set of solar spectral information, the sum of the second and third band spectral information is determined, and the quotient of the first band spectral information and the sum is determined, as the first parameter; the product of the fourth and fifth band spectral information, the reciprocal of the cosine of the sixth band spectral information, and the sine of the seventh band spectral information are determined, as the second parameter; the product of the tangent of the eighth band spectral information and the ninth band spectral information is determined, as the third parameter; and the sum of the first, second, and third parameters is determined as the intermediate value corresponding to any set of solar spectral information.

[0068] For example, the above process can be represented by the following formula:

[0069] R1=k1 / (k2+k3)+(k4*k5) / cos(k6)*sin(k7)+tan(h1)*z1

[0070] Where R1 represents the intermediate value corresponding to a certain set of solar spectral information, k1 represents the first band spectral information in the set of solar spectral information, k2 represents the second band spectral information in the set of solar spectral information, k3 represents the third band spectral information in the set of solar spectral information, k4 represents the fourth band spectral information in the set of solar spectral information, k5 represents the fifth band spectral information in the set of solar spectral information, k6 represents the sixth band spectral information in the set of solar spectral information, k7 represents the seventh band spectral information in the set of solar spectral information, h1 represents the eighth band spectral information in the set of solar spectral information, z1 represents the ninth band spectral information in the set of solar spectral information, and cos, sin, and tan represent cosine operation, sine operation, and tangent operation, respectively.

[0071] The correspondence between the spectral information of the first to ninth bands and the various bands in the solar spectrum can be determined randomly or according to preset rules. For example, the spectral information of the first band can be associated with the red light band, the spectral information of the second band with the orange light band, the spectral information of the third band with the yellow light band, the spectral information of the fourth band with the green light band, the spectral information of the fifth band with the cyan light band, the spectral information of the sixth band with the blue light band, the spectral information of the seventh band with the violet light band, the spectral information of the eighth band with the infrared band, and the spectral information of the ninth band with the ultraviolet light band.

[0072] In step S13, at least one digit is selected from each intermediate value according to the preset digit selection rule, and the selected digits are recombined to obtain the target random number.

[0073] After determining the median value corresponding to each set of solar spectral information, the median value can be digitized. Several digits can be selected from the median value, and then the selected digits can be recombine to obtain the target random number. The preset digit selection rules can include various methods, such as taking the middle two digits of each median value for recombination, or taking the first and last two digits of each median value for recombination, etc., and there are no specific limitations.

[0074] In one implementation, the digit selection rule includes the digit selection position, digit selection length, digit selection direction, and fill character corresponding to each intermediate value. Therefore, the step of selecting at least one digit from each intermediate value according to the preset digit selection rule, and recombining the selected digits to obtain the target random number may include:

[0075] For any intermediate value, determine the digit at the specified position within that intermediate value as the target number. If the length of the remaining digits along the specified direction is not less than the specified position length, select a digit of that specified position length as a candidate value for the intermediate value. If the length of the remaining digits along the specified direction is less than the specified position length, fill the remaining digits with a padding character to obtain a string that meets the specified position length, which is then used as a candidate value for the intermediate value. Randomly recombine multiple candidate values ​​to obtain the target random number. The padding character can be either a number or a letter; there are no specific restrictions.

[0076] In other words, for a given intermediate value, first determine the corresponding position, such as the starting position, the halfway point, or the one-third point, etc.; then, at the position, select a number of digits along the selection direction. For example, if the position is the halfway point, you can select two digits backward from the halfway point, or three digits forward from the halfway point. If the remaining digit length in the selection direction is less than the selection length, use padding characters to fill the gaps, resulting in a string that matches the selection length, which is then used as a candidate value. For example, continuing the above example, if there is only one digit backward from the halfway point, add a padding character to obtain a string containing two characters, which is then used as a candidate value; or, if there is only one digit forward from the halfway point, add two padding characters to obtain a string containing three characters, which is then used as a candidate value. Finally, randomly recombine multiple candidate values ​​to obtain the target random number.

[0077] In this way, the generation of random numbers involves multiple calculations through a hybrid splicing strategy of solar spectral data, which further increases the difficulty of cracking the code and helps to improve the randomness, security and uniqueness of the target random numbers.

[0078] For example, solar spectral information can include four sets, with corresponding intermediate values ​​of the first, second, third, and fourth intermediate values. Then, the position corresponding to the first intermediate value can be set to the halfway point, the position length to 3, the position direction to backward, and the fill character to 0; the position corresponding to the second intermediate value can be set to the one-third point, the position length to 1, the position direction to backward, and the fill character to 2; the position corresponding to the third intermediate value can be set to the one-quarter point, the position length to 2, the position direction to backward, and the fill character to f; and the position corresponding to the fourth intermediate value can be set to the starting position, the position length to 2, the position direction to backward, and the fill character to t.

[0079] In other words, the first intermediate value is truncated to half its length, and three positions are taken from the index. If there are fewer than three positions, 0 is added. The second intermediate value is truncated to half its length, and one position is taken from the index. If there are fewer than three positions, 2 is added. The third intermediate value is truncated to half its length, and two positions are taken from the index. If there are fewer than three positions, f is added. The fourth intermediate value is truncated to two positions from the starting position. If there are fewer than four positions, t is added.

[0080] According to the above settings, if the first median value is 56842567, then take 3 digits from the halfway point to select the candidate value corresponding to the first median value as 256; if the second median value is 94784358, then take 1 digit from the one-third point to select the candidate value corresponding to the second median value as 7; if the third median value is 60487610, then take 2 digits from the one-quarter point to select the candidate value corresponding to the third median value as 48; if the fourth median value is 40849502, then take 2 digits from the starting position to select the candidate value corresponding to the fourth median value as 40. After random recombination, the target random number is 72564048.

[0081] like Figure 2 The diagram shown is a logical schematic of a random number generation method according to an exemplary embodiment. First, considering different regional and temporal differences, the acquisition unit collects four sets of solar spectral information, recording the spectral information of the visible and invisible light bands, including:

[0082] Visible light band spectral information array: {red band spectral information, orange band spectral information, yellow band spectral information, green band spectral information, cyan band spectral information, blue band spectral information, violet band spectral information};

[0083] Invisible light band spectral information values: ultraviolet band spectral information and infrared band spectral information.

[0084] Then, the processing unit calculates the collected solar spectral information to obtain four sets of intermediate value arrays corresponding to the solar spectral information. Next, a bitwise operation is performed on the intermediate value arrays, selecting at least one digit from each intermediate value. The selected digits are then rearranged to obtain the target random number.

[0085] As can be seen from the above, the technical solution provided by the embodiments of this disclosure uses the ever-changing solar spectrum in nature to construct a highly random calculation model. Since the solar spectrum is constantly changing, the generation of random numbers is highly time-sensitive and difficult to copy and crack, thereby improving the randomness, security and uniqueness of the target random number.

[0098] In one implementation, the solar spectral information includes four sets, with corresponding intermediate values ​​being a first intermediate value, a second intermediate value, a third intermediate value, and a fourth intermediate value. The first intermediate value corresponds to a position at the halfway point, a position length of 3, a position direction of backward, and a fill character of 0. The second intermediate value corresponds to a position at the one-third point, a position length of 1, a position direction of backward, and a fill character of 2. The third intermediate value corresponds to a position at the one-quarter point, a position length of 2, a position direction of backward, and a fill character of f. The fourth intermediate value corresponds to a position at the starting point, a position length of 2, a position direction of backward, and a fill character of t.

[0099] As can be seen from the above, the technical solution provided by the embodiments of this disclosure uses the ever-changing solar spectrum in nature to construct a highly random calculation model. Since the solar spectrum is constantly changing, the generation of random numbers is highly time-sensitive and difficult to copy and crack, thereby improving the randomness, security and uniqueness of the target random number.

[0104] As can be seen from the above, the technical solution provided by the embodiments of this disclosure uses the ever-changing solar spectrum in nature to construct a highly random calculation model. Since the solar spectrum is constantly changing, the generation of random numbers is highly time-sensitive and difficult to copy and crack, thereby improving the randomness, security and uniqueness of the target random number.
