Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
In order to which vehicle device and backstage complete authentication, it is necessary to corresponding certificate is injected into vehicle device, in the initial stage of development stage,
Producing line does not integrate certificate function of injecting also, is unable to satisfy the exploitation demand of early period；In the process of development, if Developmental Engineer needs
It refills certificate or replaces certificate, then need to go to realize to producing line, need producing line to coordinate to arrange, low efficiency and process
Complexity is difficult to meet exploitation demand.
For this purpose, can satisfy the need of certificate injection and verifying certificate the present embodiment provides a kind of producing line certificate injected system
It asks.Referring to Figure 1, vehicle device including certificate to be implanted is simulated with the producing line simulation tool of vehicle device serial communication and with producing line
The KMS system of tool connection.
For car networking project, in order to guarantee the legitimacy of vehicle device and server, vehicle device upon connection platform server when, need
A two-way authentication is done, to ensure the legal of other side's identity, in order to complete authentication, needs to inject to vehicle device and demonstrate,prove
Book.Wherein producing line simulation tool injects certificate to vehicle device for convenience, to facilitate the debugging of developer, the exploitation ring of the tool
Border can be VisualStudio, and development language is c#.
Wherein, producing line simulation tool is connected to by the dll file interface for calling supplier to provide and is deployed in Intranet
KMS system sends vehicle device by serial ports for the certificate data that KMS system issues, and is saved in the security partitioning of vehicle device.
Based on above-mentioned producing line certificate injected system, on the other hand the present embodiment also provides a kind of producing line certificate method for implanting,
Including producing line simulation tool initialization procedure and certificate injection process.
Specifically includes the following steps:
S100, vehicle device and producing line simulation tool establish connection；
In this step, handshake procedure is established between vehicle device and producing line simulation tool, and the computer of producing line simulation tool is installed
After the completion of being connected with the hardware of vehicle device, producing line simulation tool is opened, is then powered on to vehicle device, powered on a string of the transmission of rear car chance and hold
Finger enables, and producing line simulation tool can return to a string of reply datas and be given to vehicle device, and vehicle device again returns to response, completes to shake hands.
S200, producing line simulation tool read the sequence number of vehicle device；
In order to guarantee that vehicle device can complete the injection of certificate, therefore, to assure that vehicle device has corresponding sequence number, and producing line simulates work
Tool sends the instruction for reading sequence number, and vehicle device can return to a string of sequence numbers.
Wherein step S100 and S200 is the preflood processing step of certificate, between step S200 and step S300, also
Increase the step of clicking initialization key, in order to complete the injection of certificate.For this purpose, initialization procedure, that is, inject the mistake of certificate
Journey can click initialization button after shaking hands successfully and reading vehicle device sequence number, to complete the injection of certificate.Specifically
It is as follows:
S300, producing line simulation tool call KMS system to generate certificate data by initialization command, and certificate data is sent out
It send to vehicle device, completes the injection of certificate data.
Refer to Fig. 2-4, certificate data injection process the following steps are included:
After S301, vehicle device receive the initialization command of producing line simulation tool transmission, the corresponding interface is called to generate certificate registration
Data；
After S302, producing line simulation tool receive the certificate registration data of vehicle device, call relevant interface that KMS system is enabled to generate card
Book data
Certificate data is sent vehicle device by S303, producing line simulation tool.
In step S303, certificate data is sent vehicle device by producing line simulation tool, in the process due to certificate data
It is larger, in order to realize that stablizing for mass data is transmitted, certificate data is disassembled as unit of frame in the present embodiment；Vehicle device often connects
A frame certificate data is received, returns to corresponding ack to producing line simulation tool；Producing line simulation tool transmits after receiving corresponding ack
Next frame certificate data, until having sent last frame.
After the injection for completing certificate data, needs to verify the integrality of certificate and complete vehicle device authentication test.
In verifying certificate integrity procedure, after vehicle device receives all certificate datas, it is complete that vehicle device returns to verifying certificate
Property signal to producing line simulation tool, producing line simulation tool calls the integrality of corresponding interface verifying certificate data.
After completing certificate integrity verification, need to complete one-time identity authentication using certificate to test, it can to ensure that certificate is
With what is used.The authentication test process is the same with the normal backstage completion authentication procedures that connect.
Based on the producing line simulation tool in above-mentioned producing line certificate injected system, the present embodiment also provides a kind of producing line simulation work
The operation sequence of tool, the operation sequence use process is as follows described:
Use step:
1, refer to Fig. 5, open catalogue ConvertPackge (17.5.9V1.1) bin Debug
PCInitSys.exe；
2, it is accomplished manually the connection of hardware serial ports；
3, it after connecting and opening serial ports, is powered on to vehicle device, simulative serial port tool can shake hands with vehicle device automatically, at this time
Initialization button goes out, and needs first to read either write sequence number；
4, Fig. 6 is referred to, clicks and reads sequence number, wherein " 43 47 30 30 31 38 32 3,130 30 30 30 30
34 " be sequence number；The sequence number of 14byte can also be written in the text box of sequence number to vehicle device write sequence number, then click
" write sequence number "；
5, Fig. 7 is referred to, after reading or writing sequence number, is clicked " initialization ", vehicle device will automatically begin to initialize.
Note: just can be performed, to wait after needing the process initiation for first waiting the SVSecurity in SOC due to initialization
After vehicle device interface is got up, then after waiting 10-20s, then click " initialization ".To ensure serial ports connection during initialization
Stablize.It is had after initializing successfully and plays frame prompt.
In conclusion producing line certificate injected system provided in an embodiment of the present invention, it can be direct by producing line simulation tool
Certificate is injected to vehicle device, in the development phase, KMS system and its certificate authority function directly can be verified by producing line simulation tool
Can, improve system builds efficiency；Facilitate engineer directly to debug vehicle device processing and save the logic of certificate, it is ensured that is going to produce
When line is debugged, the function of the part has just been completed after debugging, improves development efficiency；It needs directly make when vehicle device certificate
