The data encryption method adopts a key for encryption.
A second aspect of this embodiment provides a method for generating an identification code uuid (universal Unique identifier), which is shown in fig. 1 and includes the following steps:
and S1, acquiring the code of the product, wherein the product can be an embedded device, and the code of the embedded device at least comprises a group of main control chip codes UID of the product. The codes of the embedded device include, but are not limited to, a main control chip code uid (uniform identification) of the embedded device, a product serial code pid (product identification) of the embedded device, and some memory chip codes of the embedded device and sensor chip codes with communication interfaces, such as a temperature sensor chip code, a pressure sensor chip code, and an acceleration sensor chip code.
The code of the embedded device includes a main control chip code UID-1 of the embedded device, a serial code PID of the embedded device and a memory chip code UID-2 of the embedded device.
S2, generating a current timestamp selecting seconds from a specified date to a current time point, the specified date may be according to a common standard, such as: 1/1970; customization can also be selected, such as: 1 month and 1 day in 2000;
and S3, combining the current time stamp with the code of the product to generate an identity recognition code UUID. The merging method adopts a method of splicing according to data bits, and specifically comprises the following steps, with reference to fig. 2:
s31, the current time stamp is expressed by 16-system numbers: taking 0 min 0 s at 8 o 'clock 1/1970 as an example of the starting time, and 0 min 0 s at 0 o' clock 1/2022 as a time point of timestamp generation, the second timer is 1640966400, and the 16-system is 0x61CF 2900.
S32, the coding of the embedded device adopts 16-system digital representation; the code of the embedded device comprises a main control chip code UID-1(11170026) of the embedded device, a serial code PID (including a model number (A016), a batch number (AB01) and a serial number (0009)) of the embedded device and a memory chip code UID-2(4026) of the embedded device.
At S33, it is determined that the number of 16-ary digits is 32 and the number of connectors "-" is 4.
And S34, determining the segmentation mode of the 16-system number through the connector "-", wherein the segmentation mode of the 16-system number is as follows: 8-4-4-4-12.
S35, splicing the current timestamp and the codes of the embedded equipment in sequence according to a segmentation mode by adopting n-system digital representation to obtain an identity recognition code UUID:
(61CF2900-A016-AB01-0009-11170026-4026), referring to FIG. 3, FIG. 3 is a schematic diagram of UUID.
For the serial code PID of the device, if the data bits are insufficient, the redundant coding bits in the PID can be reduced properly, and the redundant coding can adopt a mapping conversion mode. If the code contains the complete date code: 20220202, which can be reduced to a number in the range of 0-0xFFFF, the encoded bits are reduced by half.
Some UIDs adopt digital string codes, can be represented by 16 systems during storage, further reduce code occupation, and realize that codes contain more information contents. The use of 16-ary coding saves space on code footprint, and the most space-saving is for example the decimal number 1000, denoted 0x3E8 by 16, 0x1000 by BCD8421 and 0x31303030 by ASCII.

The data shifting, data negation, data exclusive or, data mapping and data encryption methods are lossless data transformation methods, and original data can be restored; the linear equation method, the cyclic redundancy check method and the hash table residue removal method are all lossy data transformation methods, original data cannot be recovered, and the transformed data can save coding bit resources.
Example (c): the code is expressed by 16-system numbers.
Data shifting: the contract data is shifted left or right by a few bits as a whole, 0x4321 cycles left by three bits, the obfuscated data is 0x190A, and the reverse operation is to cycle right by three bits.
Data inversion: taking the code 0x4321 as an example, the inverted code is 0xBCDE, and the reverse operation is inverted again.
Data exclusive or: taking encoding 0x4321 as an example, XOR-ing with 0x1234 is then 0x5115, and the reverse operation is to XOR 0x4321 with 0x1234 again.
Data mapping: taking the encoding 0x4321 as an example, it is agreed to exchange 0bit and 7bit of each byte, and after mapping, the result is 0xC2a0, and the reverse operation is to exchange 0bit and 7bit of each byte again.
Data encryption and decryption are carried out by adopting an AES key;
the plaintext is: 154956EC2022AB 010009111700264026;
the AES key is: C5D6E7
The ciphertext is:
W618UdhXhfXMZV2Rm0xZ106XI18i/Ix1gHWZ2k1uguqgYXSAvEZZ8ai6X34KinkN。
the linear equation: the linear equation is in the form of the new code C ═ aX + bY + cZ, where X, Y, Z is the original code, a, b, C are coefficients, and C is the alias code. For example, codes 0x1234, 0x5678, and 0x9ABC are mixed by coefficients 1, 2, and 3 in this order, and the result is 0x8F58, and only the lower 16 bits of data are retained as a result of the operation.
Cyclic redundancy: taking the CRC-16/MODBUS check calculation method as an example, the CRC operation result of the code 0x123456789ABC is 0x2D 48.
Hash table residue removal method: the residue is selected to be 65521, and the hash result of encoding 0x123456789ABC is 0xACB 3.
In a third aspect of the present invention, a computer-readable storage medium is provided, where the computer-readable storage medium is used for storing a program code, and the program code is used for executing the method for generating the UUID of the identification code or the system for generating the UUID of the identification code.
