When firing key is inserted into ignition lock and opens ignition switch (rotating to ON grades), the meeting of car body controller 102 exists
Start the antitheft verification process of transponder 101 in preset maximum delay time, and assert maximum time in preset single
Primary certification of the interior completion to transponder 101.Certification between transponder 101 and car body controller 102 has stringent timing to want
It asks, is considered as certification failure at that time if time-out.
Car body controller 102 sends the certification request to transponder 101, base station to base station by serial data interface first
Certification request is sent to transponder 101 by aforementioned wireless radio frequency mode, then the authentication information of transponder 101 is passed through into string
Row data-interface is transferred to car body controller 102.Authentication information is the distinctive information of each transponder 101, with vehicle body control
The authentication information of the transponder 101 of 102 successful match of device processed can be stored in the memory of car body controller 102.Vehicle

It shows a kind of preferable implementation, according to different consideration factors, may be implemented shown in Fig. 3 all, it can also be with
It only realizes a portion shown in Fig. 3, is described in detail for whole shown in Fig. 3 included below.
A phase is written in lower generation line in the engine management system 103 and car body controller 102 of same vehicle
Same key (ESK, Engine Secret Key).Engine management system 103 first makees the random number itself generated
Car body controller 102 is issued for activation code, and car body controller 102 is by the activation code received and the key of itself storage, fixed code
A reply code is calculated by Encryption Algorithm.If the authentication result of the antitheft certification of level-one is that certification passes through, car body controller
The reply code is returned to engine management system 103 by 102, if the authentication result of the antitheft certification of level-one is authentification failure,
Car body controller 102 returns to the information of the antitheft authentification failure of level-one to engine management system 103.Further, since replying code
Calculating needs the time, and in replying Calculative Process, car body controller 102 will send " replying code encryption operation carrying out "
Return information is to engine management system 103.
In the recoil state of the car body controller 102, if the authentication result of the antitheft certification of level-one is that certification passes through, send out
Motivation management system 103 will be compared to code and internal reference value is replied, the internal reference value be also by identical activation code,
Fixed code and ESK are calculated by identical Encryption Algorithm, the difference is that fixed code and ESK herein is stored in and starts
Value in machine management system 103.Only when fixed code, ESK and the car body controller 102 stored in engine management system 103
Middle storage is consistent, and when Encryption Algorithm is identical, and engine management system 103 will be to replying code and internal reference value is compared

The time of code, engine management system 103 was still from car body controller 102 more than after preset maximum activation code sending time
It receives for indicating the ongoing information of the antitheft certification of level-one or for indicating that replying code encryption calculates ongoing information
Engine management system 103 will just stop sending activation code and notify 102 authentification failure of car body controller, and No starting starts
Machine.
If engine management system 103 is after sending activation code to car body controller 102, in preset maximum reply
It is interior not receive any reply sent from car body controller 102, judge whether the number for sending activation code reaches preset
Maximum activation code transmission times, if not up to, sending same activation code to car body controller 102, if reaching, engine
Management system 103 notifies 102 authentification failure of car body controller, and No starting engine.
If engine management system 103 receives the error return from car body controller 102, engine management system
103 need to wait preset maximum retransmission delay time, and use new random number as activation code to restart and vehicle
The identification sequences of body controller 102.Verification process is identical as first time and car body controller 102 verification process.And such as
The secondary verification process with car body controller 102 of fruit engine management system 103 still fails, regardless of type
Failure, engine management system 103 will not all do any trial again, stop sending activation code and send authentification failure signal,
No starting state is set by engine.
