Embodiment 1

[0109] The data transmission control method in this embodiment includes:

[0110] On the data provider side:

[0111] S01: Based on the agreed algorithm, the data provider adds the sending timestamp to the original data to obtain the first string carrying the sending timestamp;

[0112] Wherein, the first character string includes at least two parts, and each part is separated by 8 hexadecimal numbers FF: the first part is a 17-bit transmission time stamp, which is the current time when the original data is sent, according to year (YYYY) month ( MM) day (DD) hour (HH) minute (mm) second (ss) millisecond (SSS) sequence; the second part is the length of the original data.

[0113] S02: According to the preset first rule, two first substrings are intercepted from the first character string; the details are as follows: starting from the 50th character of the first character string, a total of 25 characters are intercepted backward, that is, intercepting The 50th to 74th bits are t...

Embodiment 2

[0133] The data transmission control method in this embodiment includes:

[0134] On the data provider side:

[0135] S01: Based on the agreed algorithm, the data provider adds the sending timestamp to the original data to obtain the first string carrying the sending timestamp;

[0136] Wherein, the first character string includes at least two parts, and each part is separated by 8 hexadecimal numbers FF: the first part is a 17-bit transmission time stamp, which is the current time when the original data is sent, according to year (YYYY) month ( MM) day (DD) hour (HH) minute (mm) second (ss) millisecond (SSS) sequence; the second part is the length of the original data.

[0137] S02: According to the preset first rule, intercept two first substrings string1 and string2 from the first character string;

[0138] S03: According to the preset second rule, rearrange the intercepted first substrings to obtain the first rearranged substrings; details are as follows: string1 and str...

Embodiment 3

[0153] The data transmission control method in this embodiment includes:

[0154] On the data provider side:

[0155] S01: Based on the agreed algorithm, the data provider adds the sending timestamp to the original data to obtain the first string carrying the sending timestamp;

[0156] Wherein, the first character string includes at least two parts, and each part is separated by 8 hexadecimal numbers FF: the first part is a 17-bit transmission time stamp, which is the current time when the original data is sent, according to year (YYYY) month ( MM) day (DD) hour (HH) minute (mm) second (ss) millisecond (SSS) sequence; the second part is the length of the original data.

[0157] S02: According to the preset first rule, intercept two first substrings string1 and string2 from the first character string;

[0158] S03: According to the preset second rule, rearrange the intercepted first substrings to obtain the first rearranged substrings, specifically: string1 and string2 are con...

Abstract

The invention provides a data transmission control method and device, a storage medium and a terminal. The method comprises: enabling a data provider to add a sending timestamp to original data basedon an agreed algorithm to obtain a first character string; intercepting and rearranging the first character string according to a preset first rule and a preset second rule to obtain a first rearranged sub-character string; adding user information data to the first rearranged sub-character string to obtain a second character string; intercepting and rearranging the second character string according to a preset third rule and a preset fourth rule to obtain a second rearranged sub-character string; and sending encrypted data formed by assembling the first character string and the second rearranged sub-character string according to a predetermined format to a data receiver. In the data transmission process of the data provider and the data receiver, the data content is encrypted and processedby using the timestamp information and the user information data, and the data receiver is verified, so that the data is not easy to crack and counterfeit, and the risk that the data content is attacked and embezzled by a third party is reduced.

Description

technical field [0001] The invention relates to the technical field of data communication, in particular to a data transmission control method, device, storage medium and terminal. Background technique [0002] The rapid development of network technology makes data transmission penetrate into all aspects of life, and the subsequent network security issues have become the focus of attention. For example, in data transmission, illegal persons will steal character strings and directly send random character strings to the server, which may steal user information. [0003] Up to now, many technologies have been proposed for data transmission control methods, such as shifting and XORing plaintext data through key operations to realize data encryption. If it cannot be decrypted correctly, only incomprehensible characters can be obtained. string (that is, garbled characters). However, due to the fixed length of the key, the time to break through the brute force method is getting s...
