In view of the problem that a password generated by using a fixed algorithm can be cracked in a reverse-pushing manner, embodiments of the present application provide a data processing method, an apparatus, an electronic device, and a computer-readable storage medium, so as to reduce the possibility of cracking the password and improve the security of data transmission, which is described below by embodiments.

The first embodiment is as follows:

to facilitate understanding of the present embodiment, a data processing method disclosed in the embodiments of the present application will be described in detail first. The data processing method is applied to first equipment, communication connection is established between the first equipment and second equipment, initialization parameters aiming at the same three-body system are set in the first equipment and the second equipment, and the initialization parameters comprise: presetting a time interval, the mass of each target particle, and an initial three-dimensional vector velocity and an initial three-dimensional space coordinate of each target particle at an initial moment; three target particles are provided; fig. 1 shows a flowchart of a data processing method provided in an embodiment of the present application, and as shown in fig. 1, the method includes the following steps:

s101: determining a second three-dimensional vector velocity and a second three-dimensional space coordinate of each target particle at a target moment according to a preset time interval, the mass of each target particle and a first three-dimensional vector velocity and a first three-dimensional space coordinate of each target particle at the first moment; the difference between the first moment and the target moment is a preset time interval, and the first moment is the previous moment of the target moment; the difference between the first time and the initial time is an integer of preset time interval.

In a three-body system, three target particles A, B, C are assumed to be in space, each of which has a mass m₁、m₂、m₃The initial three-dimensional space coordinates of the three target particles at the initial time are respectively P_A0(P_XA，P_YA，P_ZA)、P_B0(P_XB，P_YB，P_ZB)、P_C0(P_XC，P_YC，P_ZC) Three target particles at the beginning of the initial timeThe first three-dimensional vector velocity is V_A0(V_XA，V_YA，V_ZA)、V_B0(V_XB，V_YB，V_ZB)、V_C0(V_XC，V_YC，V_ZC). Then in a three system, there are two conclusions:

conclusion 1: function f (m) cannot be found₁，m₂，m₃，P_A0，P_B0，P_C0，V_A0，V_B0，V_C0T), when the initialization parameters and the target time are not known, the three-dimensional space coordinates of the three target particles at the target time t can be obtained, namely, when the initialization parameters and the target time are not known, the three-dimensional space coordinates of the three target particles at the target time t cannot be expressed by a formula.

Conclusion 2: whenever there is a change in the initialization parameters, no matter how small the change is, the three-dimensional spatial coordinates of the three target particles will be distinct over time.

In a specific embodiment, the target mass point refers to a point having mass but no volume or shape, and having no effect on the size and shape of the object, or having a non-significant effect that is negligible, we consider the object approximately as an ideal object having only mass but negligible volume and shape, to replace the object's point having mass.

The preset time interval Δ t is a value greater than 0, and the preset time interval Δ t is generally set to be small. Mass m of each target particle_a、m_b、m_cMay be the same or different; similarly, the initial three-dimensional space of each target particle may be the same or different, and the initial three-dimensional vector velocity of each target particle may be the same or different.

In a specific embodiment, the initial time is not later than the first time, and the first time differs from the initial time by an integer number of preset time intervals, for example, the integer may be 0, 1, 2, 3, etc. When the difference between the first time and the initial time is 0 preset time interval, the first time and the initial time are represented asThe same moment; when the time difference between the first time and the initial time is 1 preset time interval, the time difference indicates that the first time is the next time of the initial time, namely when the initial time is t₀When the predetermined time interval is Δ t, the first time is t₀+Δt。

In the embodiment of the application, the initial three-dimensional space coordinates P of three target particles at the initial moment_A0(P_XA0，P_YA0，P_ZA0)、P_B0(P_XB0，P_YB0，P_ZB0)、P_C0(P_XC0，P_YC0，P_ZC0) And the initial three-dimensional vector velocities V of the three target particles at the initial time_A0(V_XA0，V_YA0，V_ZA0)、V_B0(V_XB0，V_YB0，V_ZB0)、V_C0(V_XC0，V_YC0，V_ZC0) Is floating point type data.

In the embodiment of the present application, the mass of each target dot occupies 8 bytes in the device, and the mass of three target dots occupies 3 × 8-24 bytes.

The initial three-dimensional space coordinates of each target dot contain values in three directions, and the number of bytes occupied by the value in each direction is 8 bytes, so that the number of bytes occupied by the initial three-dimensional space coordinates (in the three directions) of each target dot is 3 × 8 to 24 bytes, and the number of bytes occupied by the initial three-dimensional space coordinates of the three target dots is 3 × 3 × 8 to 72 bytes.

Similarly, the initial three-dimensional vector velocity of each target dot also includes values in three directions, and the number of bytes occupied by the value in each direction is 8 bytes, so that the number of bytes occupied by the initial three-dimensional vector velocity of each target dot (in three directions) is 3 × 8 to 24 bytes, and the number of bytes occupied by the initial three-dimensional space coordinates of the three target dots is 3 × 3 × 8 to 72 bytes.

Therefore, the total mass of the three target particles, the initial three-dimensional space coordinates, and the initial three-dimensional vector velocity occupy 24+72+72 bytes 168 in the device.

S102: according to a preset condition, a first number of first target characters are selected from a first target sequence consisting of a second three-dimensional vector speed corresponding to a target moment and a second three-dimensional space coordinate, and the selected first target characters are determined as an encryption password.

And combining and arranging characters contained in the second three-dimensional vector speed and characters contained in the second three-dimensional space coordinate according to a preset condition to obtain a first target sequence, and selecting a first number of first target characters from the first target sequence. Wherein the first number is a positive integer.

S103: and encrypting the target data by using the encryption password to obtain target encrypted data, and sending the target encrypted data and the target time to the second equipment so that the second equipment generates a decryption key according to the target time.

In a possible implementation mode, the target data comprises data to be encrypted in the same encryption period; or, the target data comprises at least one data to be encrypted.
