People can browse various information through the internet and can perform activities such as payment, file sending and receiving, instant messaging and the like.

Specifically, the data structure of the encrypted data may be defined in advance so that the encrypted data is in the same form as the SHA256 sequence, thereby avoiding attracting the attention of an attacker.
In some optional embodiments of the present disclosure, a data structure of the encrypted data is as shown in fig. 4, and fig. 4 is a schematic diagram of the data structure of the encrypted data. The SHA256 sequence is a 256-bit binary character sequence, and the conversion is 64 bits as hexadecimal characters, and the data structure of the encrypted data of the embodiment of the disclosure adopts the hexadecimal characters.

Of course, it should be understood that the order of the different storage bits described above can be adjusted according to practical applications, and is only illustrated by way of example and should not be construed as limiting the technical solution of the present disclosure.
With the above explanations as background, the technical solutions of the present disclosure are explained below with reference to specific examples. Fig. 1 is a flowchart of an encrypted transmission method based on data in the form of an SHA256 sequence according to a first embodiment of the present disclosure. As shown in fig. 1, the method for encrypted transmission of data based on the SHA256 sequence format according to this embodiment may include the following steps:
s101: and acquiring data to be encrypted.
When data needs to be encrypted, the data to be encrypted needs to be acquired first. Generally, the data to be encrypted does not exceed 52 bits (hexadecimal), and when the data to be encrypted exceeds 52 bits, the data to be encrypted can be divided into data segments with the maximum length not exceeding 52 bits. The following description is made for the case where the data to be encrypted does not exceed 52 bits.
S102: and writing the data to be encrypted into the data storage bits of the transmission sequence in the SHA256 sequence form, and encrypting the data stored in the data storage bits by using an encryption key to generate encrypted data.
In this embodiment, the transmission sequence includes: the data encryption method comprises the steps of storing a storage bit of an encrypted data check code, a storage bit of an encrypted data check complement code, a storage bit of an encryption type, a storage bit of an encryption key, an initial identification bit of encrypted data in the data storage bit, and a storage bit of an encrypted data length. And generating n random numbers by using a random number generation algorithm, writing the generated n random numbers into the data storage bits, and replacing the random numbers pre-stored in the corresponding positions in the data storage bits by using the values in the data to be encrypted when the data to be encrypted is written into the data storage bits.
Specifically, a random number may be selected from the data storage bits, a start position of the selected random number is recorded in a start identification bit of the encrypted data in the data storage bits, characters of the data to be encrypted are sequentially written from the start position, and the incompletely written characters are continuously written from the start position of the data storage bits.
For example, the length of the data to be encrypted is 23 bits, the random number selected from the data storage bits is 14 th bit among 12 th to 63 th bits, and since 14+23<56, that is, the data to be encrypted can be completely accommodated from the 14 th bit to the 63 th bit of the data storage bits, the data to be encrypted is sequentially written from the 14 th bit. For another example, the length of the data to be encrypted is 23 bits, the random number selected from the data storage bits is 44 th bits of 12 th to 63 th bits, since 44+23>63, that is, the data to be encrypted cannot be completely accommodated from the 44 th bit to the 63 th bit of the data storage bits, the data to be encrypted is still sequentially written from the 44 th bit, the data to be encrypted can be written into the 63 th bit, and the remaining 3 bits are sequentially written from the 12 th bit, that is, the data to be encrypted is stored in the 12 th to 14 th bits of the data storage bits, and the 44 th to 63 th bits.
After the data to be encrypted is written into the data storage bits, the data in the data storage bits needs to be encrypted, that is, the data to be encrypted written into the data storage bits and the random numbers which are not replaced in the data storage bits are encrypted.
In the embodiment of the present disclosure, the data to be encrypted is encrypted by using an exclusive or algorithm. And encrypting the data stored in the data storage bits by using the encryption key by adopting a plurality of different XOR algorithms to generate encrypted data, wherein different encryption modes correspond to different numerical values. Specifically, the first value corresponds to no encryption operation; the second numerical value correspondingly uses the encryption key to sum the character segments in the data to be encrypted, and 16 is subtracted from the numerical value with the summation result larger than 16 until the summation result is smaller than 16; the third numerical value correspondingly uses the encryption key to perform difference calculation on the character segments in the data to be encrypted, and 16 is added to the numerical value with the difference calculation result smaller than 0 until the difference calculation result is larger than 0; the fourth numerical value correspondingly uses the encryption key to carry out XOR operation on the character segments in the data to be encrypted; the fifth numerical value correspondingly uses the encryption key to perform exclusive or operation on the character segment generated after the character segment in the data to be encrypted is turned over; the sixth numerical value corresponds to the digit of the numerical value corresponding to the encryption key in a manner of circularly translating characters in the data to be encrypted to the left; the seventh numerical value corresponds to the digit of the numerical value corresponding to the encryption key in a manner of circularly translating the characters in the data to be encrypted to the right; the character segment is the character segment in the data to be encrypted, and the length of the character segment is the same as that of the encryption key. The different values may be numbers from 0 to 6, respectively. For example, the second value (1) corresponds to summing the character segments in the data to be encrypted by using the encryption key, since it is mentioned above that the encryption key is a hexadecimal character, for example, the encryption key is a, the corresponding binary code is 1011, the character segment bit 6 in the data to be encrypted (the corresponding character segment is 0110), a +6 is greater than 16, 16 should be subtracted, and the result is 1, the encrypted character is 0001, that is, 1 is represented by hexadecimal code. Similarly, the xor operation is also performed by converting the hexadecimal code into the binary code, and then performing the xor operation on each bit of the character to be encrypted by using each bit of the key.
Through the process, the encryption of the data in the data storage bit is completed.
S103: transmitting a transmission sequence in the form of a SHA256 sequence comprising said encrypted data.
After encryption of the data in the data storage bits is completed, a transmission sequence in the form of a SHA256 sequence is sent that includes the encrypted data.
The encryption transmission method based on the SHA256 sequence form data can encrypt the data and reduce the attention of an attacker to the encrypted data.
In addition, as an optional embodiment of the present disclosure, in the above embodiment, after the encryption of the data in the data storage bits is completed, the transmission sequence may be added to a transmission queue including one or more normal SHA256 codes for transmission, that is, the transmission sequence is sent together with the normal SHA256 codes, and since the data structure of the transmission sequence is consistent with the normal SHA256 codes, it is difficult to attract the attention of an attacker. When the transmission sequence needs to be identified from the transmission queue, the common SHA256 codes in the transmission queue may be verified, and when the common SHA256 codes in the transmission queue satisfy (s + leftover)% parity = =0, it may be determined that the corresponding common SHA256 codes as the transmission sequence, where s is the sum of integer values composed of data in data storage bits, data in the data storage bits constitutes one integer value every 4 bits, leftover is an encrypted data check code, and leftover is an encrypted data check complement code. Specifically, the 12 th bit to the 63 th bit of the corresponding data storage bit in the normal SHA256 code may be sequentially combined from low to high into one integer value every 4 bits, so as to form 13 integer values, and then the values are accumulated to obtain s. And recognizing the common SHA256 code meeting the conditions as a transmission sequence, decrypting the data of the data storage bit according to the storage bit of the encryption type, the storage bit of the encryption key, the initial identification bit of the encryption data in the data storage bit and the data stored in the storage bit of the encryption data length, extracting the data to be encrypted, and completing decryption of the transmission sequence.
