Example is connected, server does decryption processing to Data0 ' using the first preset-key MK, obtains the second ciphertext data
(Rand0、HASH0)。
The process of signal control device is similar, is not described in more detail here.
Step S313 obtains the first Hash number after first data are carried out Hash operation with default hash algorithm, when
When the first Hash number is consistent with second data, the first random number is generated, and described in using first random number
Default hash algorithm obtains the second Hash number after carrying out Hash operation, and first random number and the second Hash number is pre- with first
If key obtains third encryption data after being encrypted, third encryption data is sent to the on board unit, so that described vehicle-mounted
Unit is verified after receiving the third encryption data, and when verifying is completed, then the on board unit is built with the server
Vertical interface channel.
Example is connected, server carries out Hash operation with default hash algorithm to (Rand0), if obtaining is cryptographic Hash and solution
Close obtained cryptographic Hash HASH0 is identical, then generates the first random number R and1, carries out Hash fortune with default hash algorithm to Rand1
It calculates, obtains HASH1；And using MK1 encryption (Rand1, HASH1), Data1 ' is obtained, and Data1 ' is sent on board unit.
Step S314 obtains third Hash number after the third data are carried out Hash operation with default hash algorithm, when
When the third Hash number is consistent with the 4th data, the second random number is generated, and described in using second random number
Default hash algorithm obtains the 4th Hash number after carrying out Hash operation, and second random number and the 4th Hash number is pre- with second

Preferably, first data and first random number can be subjected to Hash fortune using default hash algorithm
First key is obtained after calculation, i.e., Hash is done to (Rand0+Rand1), uses cryptographic Hash as first key TK1, that is, subsequent vehicle-mounted
Data transmission between unit and server all carries out encryption and decryption with TK1.
Likewise, the third data and second random number can also be carried out Hash using default hash algorithm
The second cipher key T K2 is obtained after operation, that is, the data transmission between follow-up signal control device and server is all added with TK2
Decryption.
Step S320, receives and stores the initial information that the on board unit is sent, and the initial information includes vehicle letter
Breath and traffic route.
Wherein, information of vehicles may include license plate number, type (fire-fighting, public security, rescue etc.), it is possible to understand that, not office
It is limited to this.
If the initial information that the on board unit is sent to server is encrypted with the first key TK1, step S320
It may include: to receive the on board unit encrypted initial information of the first key；By the encrypted initial letter
Breath is decrypted with the first key, obtains the initial information.
Step S330, if receiving the current location information that the on board unit is sent every prefixed time interval.
Wherein, prefixed time interval can be preset according to demand, such as 1 second.
If the current location information that the on board unit is sent to server is encrypted with the first key TK1, step
S330 may include: receive the on board unit is sent every prefixed time interval it is encrypted currently with the first key
Location information；Current location information is obtained after the encrypted current location information is decrypted with the first password.
Step S340, when the current location of the vehicle at a distance from the traffic intersection within a preset range, to described
Signal control device sends traffic clearance instruction, so that the vehicle passes through the traffic intersection.
Referring to Fig. 1, vehicle driving is let pass as from west to east, in order to make vehicle quickly through crossing, the traffic is let pass
Instruction can be with are as follows: west straight trip eastwards, west south are turned right, west is northwards turned left；No through traffic in other directions.
At this point, the server can for communication security, can the traffic let pass instruction encryption, therefore the step
S340 may include: that the traffic is let pass to instruct to be encrypted with second key, obtain encrypted clearance instruction；It will
The encrypted clearance instruction is sent to the signal control device, so that the signal control device second key
Decryption obtains the traffic clearance instruction.
It is extensive to send traffic to the signal control device after vehicle passes through the traffic intersection by step S350
Multiple instruction, so that the signal control device carries out the control of traffic lights according to preset rules.
At this point, the server can for communication security, can the traffic restore instruction, therefore the step S350
It may include: that the traffic is restored instruction to be encrypted with second key, obtain encrypted recovery instruction；It will be described
Encrypted recovery instruction is sent to the signal control device, so that the signal control device the second key solution
It is close, it obtains the traffic and restores instruction.
Traffic data processing method provided in an embodiment of the present invention, by constantly obtaining the current location information of vehicle, and
According to the traffic route of the current location information and vehicle, come judge vehicle at that time whether exterior traffic crossing, if reached,
Then the signal control device sends traffic clearance instruction, so that the vehicle passes through the traffic intersection, when vehicle passes through road
After mouthful, traffic is sent to the signal control device and restores instruction, so that the signal control device is carried out according to preset rules
The control of traffic lights, this mode are conducive to the arrival scene of special vehicle quickly, safe, execute task；And due to
Information of vehicles and traffic route are stored in server, are advantageously implemented monitoring and management to vehicle.Further, Ke Yitong
It crosses between server and on board unit, server and signal control device and establishes exit passageway, complete the safe transmission of data.And
And, it is to be understood that the method input cost is low, favorable expandability.
