Referring to fig. 6, before the system 10 for anti-theft security authentication is put into use, each key and identifier need to be written into each component of the system 10 for anti-theft security authentication, so that, on the basis of the first embodiment, steps 208 to 209 may be added, which are as follows:
step 208, the offline learning device acquires the vehicle identification code, and generates a user key, a key, an engine key and an electronic lock key according to the vehicle identification code; the user keys comprise a first user key and a second user key, the key keys comprise a first key, a second key and a third key, the engine keys comprise a first engine key and a second engine key, and the electronic lock keys comprise a first electronic lock key, a second electronic lock key and a third electronic lock key.
Specifically, the vehicle id is generally a vehicle chassis number, which is a string of characters consisting of a plurality of letters and numbers, and has uniqueness, wherein the user key consists of four digits or letters or a mixture of numbers and letters, for example, let the user key be a1A2A3A4The specific generation process is as follows: obtaining the third last digit character V of the vehicle identification code3According to V3To obtain A1And A2，A1Is 9-V3Value of (A)2Is 10-V3A value of (d); obtaining last character V of vehicle identification code1And a detection station G according to V1And G to give A3And A4Wherein, if 9-G is not less than 7, then A3Is 3+ V1The ones digit of the value of (a); a. the4Is 7+ V1The ones digit of the value of (a) is in the corresponding character X in the preset first corresponding table; if 7 is more than or equal to 9-G is more than or equal to 5, then A3A single digit of a value of 7+ V1; a. the4Is 3+ V1The ones digit of the value of (a) is in the corresponding character X in the preset first corresponding table; if 5 is more than or equal to 9-G is more than or equal to 3, then A3Is 1+ V1The ones digit of the value of (a); a. the4Is 9+ V1The ones digit of the value of (a) is in the corresponding character X in the preset first corresponding table; if 3 is more than or equal to 9-G is more than or equal to 1, then A3Is 5+ V1The ones digit of the value of (a); a. the4Is 5+ V1The ones digit of the value of (a) is in the corresponding character X in the preset first corresponding table; if 9-G is less than or equal to 1, then A3Is 9+ V1The ones digit of the value of (a); a. the4Is 1+ V1According to A, the ones of the values of (A) correspond to the corresponding characters X in a preset first corresponding table1、A2、A3And A4Then the user key A can be generated1A2A3A4. Is worth mentioningIs that V1、V3And G are each an integer of 0 to 9 inclusive.
It is noted that the third last digit character V of the vehicle identification code3Last character V1And the detection station G is a number, the first corresponding table stores the corresponding relation between the number 0-9 and letters or numbers, and can be set by a vehicle manufacturer, for example, 1 corresponds to 7, 8 corresponds to C and the like in the first corresponding table. The user key generation process will be described below by taking a specific example, for example: v3Is 3, V1Is 1, G is 1, and 8 in the first mapping table corresponds to C, then A1Is 6, A2Is 7, A3Is 4, A4C, the user key is 674C.
The key is composed of ten digits or letters or a mixture of digits and letters, e.g. let the user key be C1C2C3C4C5C6C7C8C9C10The engine key is composed of eight digits or letters or a mixture of the digits and the letters, and the engine key is C1C2C3C4C5C6C7C8The electronic lock key is composed of two digits or letters or a mixture of the digits and the letters, and is C9C10. The specific generation process is as follows: obtaining the third last digit character V of the vehicle identification code3The penultimate character V of the vehicle identification code2And the last character V of the vehicle identification code1According to V1、V2And V3To obtain C1～C10Wherein, C1＝V3，C2＝V2，C3Is a V1+V2Ones of the value of (C)4Is a V2-V1Absolute value of (C)5Is a V1+V3Ones of the value of (C)6Is a V3-V1Absolute value of (C)7Is a V2+V3Ones of the value of (C)8Is a V3-V2Is in a preset rangeCorresponding characters Y, C in two correspondence tables9Is a V1+V2+V3Ones of the value of (C)10Is a V3-V2-V1The ones digit of the absolute value of the character is in a corresponding character Z in a preset third corresponding table; according to C1～C10Then the key secret key C can be generated1C2C3C4C5C6C7C8C9C10Engine key C1C2C3C4C5C6C7C8And electronic lock key C9C10. It is worth mentioning that V1、V2And V3Are integers of 0 or more and 9 or less.
It should be noted that the second correspondence table and the third correspondence table both store correspondence between numbers 0 to 9 and letters or numbers, and the second correspondence table and the third correspondence table may be set by a vehicle manufacturer, for example, 3 corresponds to F, 7 corresponds to 4 in the second correspondence table, 2 corresponds to 9, 5 corresponds to C in the third correspondence table, and so on. The generation process of the key, the engine key and the electronic lock key will be described below by taking a specific example, for example: v3Is 3, V2Is 0, V1Is 1, 3 in the second correspondence table corresponds to F, 2 in the third correspondence table corresponds to 9, C1Is 3, C2Is 0, C3Is 1, C4Is 1, C5Is 4, C6Is 2, C7Is 3, C8Is F, C9Is 4, C10Is 9, so the key is 3011423F49, the engine key is 3011423F, and the electronic lock key is 49.
