[0031] like Figure 1 As shown, the system architecture may include a server 101, a network 102 and a terminal device 103. The network 102 is used to provide a medium for a communication link between the terminal device 103 and the server 101.

[0036] Below, each step of the data encryption method in the exemplary embodiment of the present disclosure will be described in more detail with reference to the accompanying drawings and embodiments.

[0037] Figure 2 is a flow chart of a data encryption method according to an exemplary embodiment. The method provided by the embodiment of the present disclosure can be performed as follows Figure 1 The encryption end is shown to be executed, but the present disclosure is not limited to this.

[0038] like Figure 2 As shown, the data encryption method provided by the embodiment of the present disclosure may include the following steps.

[0039] In step S202, the data to be encrypted and the encryption key are obtained.

[0040] In the embodiments of the present disclosure, the data to be encrypted may include but is not limited to images, audio, video, and text; the encryption key may include but is not limited to images, audio, video, and text.

[0041] In the following examples, the data to be encrypted and the encryption key are both texts, but the present disclosure is not limited to this.

[0042] In step S204, a physical field is generated according to the data to be encrypted and the encryption key.

[0043] In the embodiments of the present disclosure, the physical field may be an electric field, a magnetic field or a gravitational field. The physical field may also be a composite field of an electric field and a magnetic field. The physical field may also be a composite field of an electric field and a gravitational field. The physical field may also be a composite field of a magnetic field and a gravitational field. The physical field may also be a composite field of an electric field, a magnetic field and a gravitational field.

[0044] In an exemplary embodiment, the physical field is a composite field of electric field, magnetic field and gravitational field.

[0045] In the disclosed embodiment, the first number to be encrypted can be determined based on the data to be encrypted and the first code table; the second number to be encrypted can be determined based on the encryption key and the second code table; wherein the first code table and the second code table can use different code tables to increase the security of encryption.

[0046] For example, the data to be encrypted may be split into individual characters, and the numerical value corresponding to each character may be obtained by searching in the first code table, and these numerical values ​​may be arranged in sequence to obtain the first number A1 to be encrypted.

[0047] The first number to be encrypted may be set to 256 bits. If the first number to be encrypted is less than 256 bits, it may be supplemented with 1 or 0. For example, 1 may be supplemented at the first digit of the first number to be encrypted, and 0 may be supplemented after 1.

[0048] For example, the encryption key may be split into individual characters, and the numerical value corresponding to each character may be obtained by searching in the second code table, and these numerical values ​​may be arranged in sequence to obtain the second number A2 to be encrypted.

[0049] In the disclosed embodiment, the physical parameters of the physical field may be determined according to the first number to be encrypted and the second number to be encrypted.

[0050] For example, the first number to be encrypted A1 can be divided by the second number to be encrypted A2 to obtain the result B1; the first number to be encrypted A1 can be divided by the second number to be encrypted A2 and the result B1 can be rounded to the integer; the first number to be encrypted A1 can be divided by the second number to be encrypted A2 and the result B2 can be obtained by taking the remainder.

[0051] In the disclosed embodiment, the physical parameters of the physical field may be determined based on the relevant characteristic values ​​of B1 and B2.

[0052] The relevant characteristic values ​​may include the number of digits and the specific values ​​of each digit.

[0053] In an exemplary embodiment, the physical parameters include the magnitude of the electric field and the direction of the electric field.

[0054] The direction of the field strength may be horizontal to the left, horizontal to the right, vertically upward, vertically downward, etc.

[0055] For example, the direction of the field strength of the electric field, magnetic field or gravitational field can be determined based on the number of digits in B1. If the number of digits in B1 is an odd number, the field strength direction is horizontally to the left (or horizontally to the right); if the number of digits in B1 is an even number, the field strength direction is vertically upward (or vertically downward).

[0056] For example, the direction of the field strength of the electric field, magnetic field or gravitational field can be determined based on the number of digits of B1 modulo 4. If the number of digits of B1 modulo 4 is 0, the field strength direction is horizontal to the left; if the number of digits of B1 modulo 4 is 1, the field strength direction is horizontal to the right; if the number of digits of B1 modulo 4 is 2, the field strength direction is vertically upward; if the number of digits of B1 modulo 4 is 3, the field strength direction is vertically downward.

[0057] For example, the direction of the field strength of the electric field, magnetic field or gravitational field can be determined based on the number of digits in B2. If the number of digits in B2 is an odd number, the field strength direction is horizontally to the left (or horizontally to the right); if the number of digits in B2 is an even number, the field strength direction is vertically upward (or vertically downward).

[0058] For example, the direction of the field strength of the electric field, magnetic field or gravitational field can be determined based on the number of digits of B2 modulo 4. If the number of digits of B2 modulo 4 is 0, the field strength direction is horizontal to the left; if the number of digits of B2 modulo 4 is 1, the field strength direction is horizontal to the right; if the number of digits of B2 modulo 4 is 2, the field strength direction is vertically upward; if the number of digits of B2 modulo 4 is 3, the field strength direction is vertically downward.

[0059] For example, the strength of the electric field, magnetic field or gravitational field can be determined based on the first three digits (or the first two digits, the middle two digits, the middle three digits, the last three digits, the last two digits, etc.) of the number B1.

[0060] For example, the strength of the electric field, magnetic field or gravitational field can be determined based on the first three digits (or the first two digits, the middle two digits, the middle three digits, the last three digits, the last two digits, etc.) of the number B2.

[0061] In the disclosed embodiments, a physical field may be generated according to physical parameters of the physical field.

[0062] In the disclosed embodiment, a physical field may be generated based on the determined field strength direction and magnitude of the electric field, the field strength direction and magnitude of the magnetic field, and the field strength magnitude and direction of the gravitational field.

[0063] It should be noted that the field strength of the electric field, the field strength of the magnetic field, and the field strength of the gravitational field may be 0, and the present disclosure does not impose any limitation on this.

[0064] In step S206, the attribute value of the charged particle is determined according to the data to be encrypted.

[0065] In the disclosed embodiment, the first number A1 to be encrypted may be determined according to the data to be encrypted and the first code table.

[0066] For example, the data to be encrypted may be split into individual characters, and the numerical value corresponding to each character may be obtained by searching in the first code table, and these numerical values ​​may be arranged in sequence to obtain the first number A1 to be encrypted.

[0067] In the disclosed embodiment, the property value of the charged particle may be determined according to the first number to be encrypted.

[0068] For example, the first number to be encrypted A1 can be divided by a preset number to obtain a result C1; the first number to be encrypted A1 can be divided by a preset number and rounded to obtain a result C1; the first number to be encrypted A1 can be divided by a preset number and modulo to obtain a result C2. The preset number can be 256, or can be set according to actual needs, and the present disclosure does not limit this.

[0069] In the disclosed embodiment, the property value of the charged particle may be determined based on the relevant characteristic values ​​of C1 and C2.

[0070] The relevant characteristic values ​​may include the number of digits and the specific values ​​of each digit.

[0071] In an exemplary embodiment, the property value of the charged particle includes at least one of a charged property of the charged particle, a charge amount, an initial velocity of the charged particle entering the physical field, and an incident coordinate.

[0072] For example, the charge property of a charged particle can be determined based on the number of digits in C1. If the number of digits in C1 is an odd number, the charged particle is positively charged; if the number of digits in C1 is an even number, the charged particle is negatively charged.

[0073] For example, the charge of a charged particle, the initial velocity of the charged particle entering the physical field, and the incident coordinates can be determined based on the first three digits of C2 (it can also be the first two digits, the middle two digits, the middle three digits, the last three digits, the last two digits, etc.).

[0074] For example, the charge properties of charged particles can be determined based on the number of digits in C2, and the charge amount of charged particles, the initial velocity of charged particles entering the physical field, and the incident coordinates can be determined based on the specific values ​​of each digit in C1.

[0075] It should be noted that the initial velocity of the charged particles entering the physical field may be 0, and the present disclosure does not impose any limitation on this.

[0076] In step S208, a target motion trajectory diagram of the charged particles is obtained according to the property values ​​of the charged particles and the physical field.

[0077] In the disclosed embodiment, the charging properties, charge amount, initial velocity and incident coordinates of the charged particles, and the magnitude and direction of the field strength of the physical field can be determined according to the above steps.

[0078] In the disclosed embodiment, the charged particles may be placed in the physical field to generate a target motion trajectory diagram of the charged particles.

[0079] Among them, placing charged particles into a physical field to obtain a target motion trajectory diagram of the charged particles can be obtained by direct calculation, through actual experimental operations, or through simulation software, and the present disclosure does not impose any restrictions on this.

[0080] In step S210, the encryption result of the data to be encrypted is obtained according to the coordinates of the charged particles in the target motion trajectory diagram of the charged particles.

[0081] In the embodiment of the present disclosure, part of the horizontal and vertical coordinates of the charged particles in the target motion trajectory diagram of the charged particles may be used as the encryption result of the data to be encrypted.

[0082] For example, the horizontal and vertical coordinates of a preset number (for example, 18) of points can be selected from the target motion trajectory diagram, and each coordinate can be accurate to two decimal places. The decimal point can be removed and the numbers can be concatenated in sequence to form a new number as the encryption result, or the number can be converted to 32-bit base 3 and used as the encryption result.

[0083] The data encryption method provided by the embodiment of the present disclosure can be applied in the process of storing user accounts and passwords.

[0084] The data encryption method provided by the embodiment of the present disclosure generates a physical field according to the data to be encrypted and the encryption key, determines the property value of the charged particle according to the data to be encrypted, combines the law of energy conversion, the law of uniformly accelerated motion, and the law of motion of objects under multiple forces, generates a target motion trajectory diagram of the charged particle, and obtains the encryption result of the data to be encrypted according to the coordinates of the charged particle in the target motion trajectory diagram of the charged particle. The data encryption method is an irreversible encryption method, and the encryption key is used to encrypt the data. The encrypted data cannot be reversely decrypted by the encryption key, which greatly increases the security of the data, reduces the situation where the encryption result is reversely decrypted according to the rainbow table due to the leakage of the encryption key, and improves the anti-attack ability of the encrypted data. In addition, according to the data encryption method, different encryption results can be obtained for the same data to be encrypted, thereby improving the security and anti-attack ability of the encrypted data.
