[0002] The problem of product counterfeiting is a long-standing one. While many companies have made significant efforts to prevent and combat counterfeiting, achieving some success, counterfeit and inferior products continue to persist. To regulate market order and prevent counterfeit and inferior goods from impacting product prices, damaging product image, undermining product credibility, and disrupting the market, manufacturers often print anti-counterfeiting codes on their products.

[0003] At present, anti-counterfeiting code encryption generation algorithms emerge in an endless stream, but most encryption generation algorithms have problems such as insufficient encryption strength and low algorithm efficiency. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a method, system, device and storage medium for generating an anti-counterfeiting code from a product number, which has the characteristics of high encryption strength and is not easy to crack.

[0011] First, the product's unique number and serial number are encrypted sequentially using the AES algorithm. The plaintext and key used in the AES encryption algorithm are reset using the product's unique number and serial number. The AES encryption result is combined with the product's unique number and serial number in an array operation to generate a plaintext. The plaintext is then subjected to a full-code conversion algorithm based on a predetermined number of arrays to generate the anti-counterfeiting code.

[0070] To make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention are described in further detail below with reference to the accompanying drawings.

[0071] like Figure 1 As shown, the method for generating an anti-counterfeiting code from a product number of the present invention comprises the following steps:

[0072] Step S1: Generate a unique number P for the product number according to a predetermined rule, and take a value N for the product sequence number within a predetermined length range;

[0073] Step S2: Perform AES encryption on the product number P and product serial number N according to the predetermined plaintext M1, plaintext M2, and key, and obtain the authentication code after taking the modulus algorithm;

[0074] Step S3: combining the product number, product serial number and authentication code into a plain code M;

[0075] Step S4, performing a full code conversion algorithm on the plain code according to the predetermined one-dimensional array key, the two-dimensional array cv, and the 10*10 two-dimensional arrays la0, la1, la2, la3, la4, la5, la6, and la7 to obtain an anti-counterfeiting code array;

[0076] Step S5: convert the anti-counterfeiting code array into a fixed-base character string to obtain an anti-counterfeiting code.

[0077] First, the product's unique number and serial number are encrypted sequentially using the AES algorithm. The plaintext and key used in the AES encryption algorithm are reset using the product's unique number and serial number. The AES encryption result is combined with the product's unique number and serial number in an array operation to generate a plaintext. The plaintext is then subjected to a full-code conversion algorithm based on a predetermined number of arrays to generate the anti-counterfeiting code. Therefore, compared to other anti-counterfeiting code encryption generation algorithms, the generation method of the present invention has the characteristics of high encryption strength and extreme difficulty in cracking, thereby ensuring the uniqueness and unforgeability of the anti-counterfeiting code.

[0078] Here, the anti-counterfeiting code array is converted into a fixed-base character string. The fixed-base character string can be hexadecimal, dodecimal, octal, etc., which is not limited here.

[0079] The product number in step S1 has P digits, Pn, including numeric characters '0' to '9'; the product serial number has N digits, Sn, including numeric characters '0' to '9'.

[0080] like Figure 2 As shown, the AES encryption operation in step S2 includes the following steps:

[0081] Step S2-1, converting the product number P into a hexadecimal product number array Pu, and converting the product sequence number N into a hexadecimal product sequence number array Su;

[0082] Step S2-2, iteratively replace the 1st, 3rd, ..., 2*Pn-1th bit data in the plaintext M1 according to the product number array to obtain plaintext M1-1;

[0083] Step S2-3, iteratively replace the 3rd, 6th, ..., 3*Pn bits of data in the key according to the product number array to obtain a new key K1;

[0084] Step S2-4: Perform AES encryption on the plaintext M1-1 and the new key K1 to obtain a first operation value, namely, the key K2;

[0085] Step S2-5, iteratively replace the 0th, 2nd, ..., 2*Sn-2th bit data in the plaintext M2 according to the product sequence number array to obtain plaintext M2-1;

[0086] Step S2-6: Use the key K2 to perform AES encryption on the plaintext M2-1 to obtain the second operation value, that is, the array K3.

[0087] It is used to reset the plaintext and key used in the AES encryption algorithm, the unique product number, and the product serial number.

[0088] like Figure 3 As shown, the modulo algorithm in step S2 includes the following steps:

[0089] Step S2-7, perform a modulo 10 operation on the array K3 bit by bit to obtain the third operation value, i.e., the array K3-1;

[0090] Step S2-8, take the 0th bit of the array K3-1 to obtain n1, i.e., iFirst;

[0091] Step S2-9, sum the array K3-1 from the first position to the iFirst position to obtain the fourth operation value, i.e., K3-2;

[0092] Step S2-10, perform a modulo 10 operation on K3-2 to obtain n2, i.e., iSecond;

[0093] Step S2-11, summing the iFirst+2th to 15th bits of the array K3-1 to obtain the fifth operation value, i.e., K3-3;

[0094] Step S2-12, perform a modulo 10 operation on K3-3 to obtain n3, i.e., iThree;

[0095] Step S2-13: Combine iFirst, iSecond, and iThree into an array to obtain the authentication code R, and proceed to step S3.

[0096] Used to perform a modulo algorithm on the AES algorithm encryption result to obtain the authentication code.

[0097] like Figure 4 As shown, the full code conversion algorithm in step S4 includes the following steps:

[0098] Step S4-1, cyclically assign values ​​to the one-dimensional array key bit by bit to obtain a one-dimensional array k; cyclically assign values ​​to the plaintext bit by bit to obtain a one-dimensional array X;

[0099] Step S4-2, performing 14 iterative operations on the one-dimensional array k and the one-dimensional array X to obtain a one-dimensional array X1;

[0100] Step S4-3: Shift the one-dimensional array X1 left by 8 bits to obtain an anti-counterfeiting code array Z.

[0101] The single iterative operation in the 14 iterative operations in step S4-2 includes the following steps:

[0102] Step S4-21, performing eight iterations of value assignment operations on the one-dimensional array k and the one-dimensional array X to obtain a one-dimensional array Zh;

[0103] Step S4-22, performing an 8-bit left shift operation on the one-dimensional array X, and assigning the first 8 bits of the one-dimensional array Zh to the last 8 bits of the one-dimensional array X to obtain the one-dimensional array X1;

[0104] Step S4-23: right-shift the one-dimensional array k by 1 bit to enter the next round of iteration.

[0105] The anti-counterfeiting code can be obtained by performing a full code conversion algorithm on the plain code according to a predetermined plurality of arrays.

[0106] Furthermore, the nth iteration of the eight iterations of the value assignment operation comprises the following steps:

[0107] Step S4-211: Take cv[j][0] to get t1, take cv[j][1] to get t2, take X[t1] to get Xu, take X[t2] to get Xw;

[0108] Step S4-212: Take Xu + k[j] to get Xuk, and perform a modulo 10 operation on Xuk to get Gu;

[0109] Step S4-213: Take Xw+k[j+8] to obtain Xwk, perform a modulo 10 operation on Xwk to obtain Qu, and take la[j][Gu][Qu] to obtain Yu;

[0110] Step S4-214: Calculate Yu + X[j] to obtain YuX, perform a modulo 10 operation on YuX to obtain YuX1, and then calculate Zh[j] = YuX1 to proceed to the next iteration. This is used to perform eight iterations of the assignment operation on the one-dimensional array k and the one-dimensional array X to obtain the one-dimensional array Zh.

[0197] Step S5: Convert the anti-counterfeiting code array Z into a hexadecimal or decimal character string to obtain a 12-digit anti-counterfeiting code 193032152719.

[0198] From the analysis of the above-mentioned specific embodiments 1 and 2, it can be seen that the anti-counterfeiting code generated by the method for generating an anti-counterfeiting code from a product number provided by this patent is not only related to the predetermined plaintext, key, and array, but also depends on the combination of the number of digits of the product number and the product serial number. Therefore, compared with other anti-counterfeiting code encryption generation algorithms, the method for generating an anti-counterfeiting code from a product number of the present invention has the characteristics of high encryption strength and is extremely difficult to crack, so as to ensure the uniqueness and unforgeability of the anti-counterfeiting code.

[0199] like Figure 7 As shown, the system for generating anti-counterfeiting codes from product numbers of the present invention includes a character string generation module, an authentication code generation module, a plain code generation module, an anti-counterfeiting code array generation module, and an anti-counterfeiting code generation module, and uses the above-mentioned method for generating anti-counterfeiting codes from product numbers to generate anti-counterfeiting codes;

[0200] String generation module: used to generate a unique number P for the product number according to a predetermined rule, and to take a value N for the product sequence number within a predetermined length range;

[0201] Authentication code generation module: used to perform AES encryption operation on product number P and product serial number N according to the predetermined plain text M1, plain text M2 and key, and obtain the authentication code after taking the modulus algorithm;

[0202] A plain code generation module: used to combine the product number, product serial number and authentication code into a plain code;

[0203] The anti-counterfeiting code array generation module is used to perform a full code conversion algorithm on the plain code according to the predetermined one-dimensional array key, the two-dimensional array cv, and the 10*10 two-dimensional arrays la0, la1, la2, la3, la4, la5, la6, and la7 to obtain the anti-counterfeiting code array;

[0204] The anti-counterfeiting code generating module is used to convert the anti-counterfeiting code array into a fixed-base character string to obtain the anti-counterfeiting code.

[0205] The AES algorithm is used to encrypt the product's unique number and serial number. The plaintext and key used in the AES encryption algorithm are reset using the product's unique number and serial number. The AES encryption result is combined with the product's unique number and serial number in an array operation to generate a plaintext. The plaintext is then converted to a full-code format using a predefined array of multiple arrays to generate the anti-counterfeiting code. Therefore, compared to other anti-counterfeiting code encryption generation systems, the generation system of the present invention boasts high encryption strength and is extremely difficult to crack, ensuring the uniqueness and unforgeability of the anti-counterfeiting code.
