Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
An exemplary embodiment of the present invention provides a communication method, and as shown in fig. 1, a processing flow of the method may include the following steps:
step S101, position information and a traveling direction of the first vehicle are acquired.
In an implementation, a Road Side Unit (RSU) may acquire position information and a driving direction of a first vehicle, and the position information and the driving direction may be transmitted by the first vehicle to the Road side device. A key agreement operation may first be performed with the roadside device before the first vehicle transmits any specific content.
The first vehicle may acquire an identity certificate of the first vehicle, and the first vehicle may perform signature processing on information based on the identity certificate of the first vehicle and send the signed information to the roadside device. The identity Certificate may be a Certificate issued by an Authority department, which may be a vehicle registration management department, etc., and the identity Certificate is signed by a Certificate Authority (CA).
The roadside device can also acquire an identity certificate of the roadside device, and the roadside device can also perform signature processing on information based on the identity certificate of the roadside device and send the information after the signature processing to the first vehicle. In this way, the roadside apparatus and the first vehicle can perform the authentication process based on the information after the signature process, which may also be referred to as a bidirectional authentication process. After passing through the bidirectional authentication process, the roadside apparatus may perform a key agreement operation with the first vehicle, and the first vehicle and the roadside apparatus may determine a communication key K required for their communication, respectivelySI. Communication key KSIMay be a symmetric key.
Negotiating a consistent communication key K between a first vehicle and a roadside deviceSIThereafter, the communication key K can be basedSICommunication is performed. The first vehicle may determine current position information and a driving direction, and a direction indicating device may be installed in the first vehicle, and the driving direction may be determined by the direction indicating device. After determining the current position information and the driving direction, the first vehicle may be based on the communication key KSIAnd encrypting the position information and the driving direction, and transmitting the encrypted position information and the encrypted driving direction to the roadside device. The roadside device may be based on the communication key KSIAnd decrypting the encrypted position information and the encrypted driving direction to acquire the position information and the driving direction of the first vehicle.
Or, the roadside device may also acquire position information of the first vehicle at a time when the two time intervals are the preset intervals, and determine the driving direction of the first vehicle based on the two position information. Still alternatively, the roadside apparatus may determine the traveling direction of the first vehicle based on the signal strength with the first vehicle.
Step S102, a position area which the first vehicle is possible to drive into is predicted based on the position information and the driving direction of the first vehicle.
In an implementation, a location area into which the first vehicle is likely to travel may be predicted based on location information of the first vehicle, a travel direction, and preset street network information. For example, as shown in fig. 2, the roadside apparatus may determine a first street on which the first vehicle is located based on the position information of the first vehicle and the street network information. Then, the roadside apparatus may determine all streets, including the second street and the third street, that the first vehicle may enter along the current driving direction, based on the driving direction of the first vehicle and the street network information.
And step S103, determining the roadside equipment corresponding to the position area.
In implementation, each roadside device corresponds to a fixed communication range, and after the installation position of any roadside device is selected, the communication range which can be covered by the roadside device is also fixed. The communication ranges of all roadside devices in the traffic system may be predetermined. After determining the location area into which the first vehicle is likely to travel, the current roadside device M may determine a roadside device that covers the location area into which the first vehicle is likely to travel.
Optionally, the step of determining the roadside apparatus corresponding to the location area may include: determining a first roadside device of a communication range coverage position area and a second roadside device adjacent to the first roadside device.
In implementation, in addition to determining the first roadside device of the communication range coverage location area, in the method provided in the embodiment of the present invention, after determining the first roadside device, a second roadside device associated with the first roadside device may be determined, where the second roadside device may be a device adjacent to the first roadside device, or a roadside device adjacent to the first roadside device.
Since the first vehicle may enter the communication range covered by the first roadside device, the first vehicle may also enter the communication range covered by the second roadside device adjacent to the first roadside device after a period of time.
Step S104, a first communication key corresponding to the first vehicle is obtained.
In implementation, as described above, the roadside device may determine the communication key K corresponding to the first vehicle through key agreement with the first vehicleSIThe roadside device may be based on the communication key KSICommunicating with a first vehicle.
Step S105, the first communication key is sent to the roadside device, so that the roadside device can communicate with the first vehicle based on the first communication key.
In implementation, the current roadside device M may determine the communication key K corresponding to the first vehicle through key agreement with the first vehicleSIIn the traffic system, a plurality of roadside apparatuses may be provided, including the current roadside apparatus M. For a plurality of roadside devices in a traffic system, a communication key is needed to be used in the process of communicating each roadside device with a first vehicle, and the process of communicating all the roadside devices with the first vehicle is neededIn (3), the same communication key, such as communication key K, may be usedSI. The communication key may be a symmetric key. At the beginning of establishing the traffic system, a plurality of roadside devices may perform key agreement based on the identity certificate, the agreed communication key may be used for communication between the roadside devices, and the agreed communication key may be a communication key of a long-term shared nature.
In this way, as long as the first vehicle accesses the traffic system, the same communication key can be used all the time, and different roadside devices can share the communication key, so that when the first vehicle switches to the accessed roadside device, the first vehicle does not need to negotiate the key with the newly accessed roadside device again. Thus, the computational overhead required for the key agreement operation is saved. Meanwhile, due to the fact that the time consumption of the key agreement process is long, multiple key agreement processes can be avoided through the method provided by the embodiment of the invention, the timeliness of determining the communication key of the roadside device and the first vehicle is improved, and the real-time performance of the communication process can be improved.
In order to further improve the real-time performance of the communication process, the current roadside apparatus M may predict a greater number of roadside apparatuses with higher accuracy, and may transmit the first communication key with the first vehicle to the determined roadside apparatuses in advance. The roadside device that receives the first communication key may store the first communication key locally, may perform communication based on the first communication key and the first vehicle if the first vehicle does enter a local communication range, and may delete the first communication key if the first vehicle does not enter the local communication range within a preset time period.
The first vehicle may be an unmanned vehicle, a manned vehicle, the first vehicle may be an automotive vehicle, an electric vehicle, or the like. The first vehicle may include an On Board Unit (OBU), and a part of the first vehicle in the method provided by the embodiment of the present invention may be implemented by the OBU. The method provided by the embodiment of the invention can be used in an unmanned scene, an assisted driving scene in a manned scene, and other possible scenes, and the embodiment of the invention is not limited. The method provided by the embodiment of the invention can be implemented based on a safety communication system, as shown in fig. 3, the system can comprise a current roadside device M, a first vehicle and other roadside devices M'.
Optionally, the method provided in the embodiment of the present invention may further include: determining a second vehicle having a communication need with the first vehicle; generating a second communication key of the first vehicle and the second vehicle; encrypting the second communication key by the first communication key; and sending the encrypted second communication keys to the first vehicle and the second vehicle respectively.
In implementation, the first vehicle is in the communication range of the current roadside apparatus M, and the communication range also includes a second vehicle, which may be one vehicle or a plurality of vehicles. All vehicles in the same communication range as the first vehicle may be determined as the second vehicle. The present roadside apparatus M may generate a second communication key required for communication between the first vehicle and the second vehicle for the first vehicle and the second vehicle. If the second vehicle is a plurality of vehicles, the second communication key may also be a plurality of keys, with different second vehicles using different keys.
Assuming that the set of vehicles with communication needs with the first vehicle is { V }, a plurality of duplets are included in { V }, each duplet being the first vehicle and a corresponding second vehicle, the duplet may be denoted as (I, J), where I represents the first vehicle, J represents the current second vehicle, and J belongs to { V }. Roadside equipment and first vehicle OBUICan be noted as KSIRoadside equipment and second vehicle OBUJCan be noted as KSJ，OBUIAnd OBUJCan be recorded as KIJ. Can pass through KSITo KIJEncryption by KSJTo KIJEncrypted, will pass KSIEncrypted KIJIs sent to the OBUIWill pass through KSJEncrypted KIJIs sent to the OBUJ. Since there are a plurality of second vehicles in the vehicle set { V }, the above operation can be performed for each second vehicle until the communication keys of the first vehicle and each second vehicle are obtained, and encryption will be performedAnd transmitting each processed communication key to the corresponding vehicle. Sending encrypted KIJWhile the OBU can be usedIAnd OBUJIs sent to the corresponding vehicle so that the vehicle can determine the specific vehicle to which the received communication key corresponds by identification. The communication key is only known to the device it is legally holding during the transmission and subsequent communication phases. The first vehicle and the second vehicle may encrypt and integrity protect the communication information with a symmetric encryption algorithm and a message authentication code algorithm using a second communication key.
Optionally, the second vehicle is a vehicle whose distance from the first vehicle is less than or equal to a preset distance threshold.
In practice, in addition to determining all vehicles within the same communication range as the vehicle having the communication demand with the first vehicle, the vehicles may be screened. These vehicles may be screened according to distance, direction of travel, speed, current location, etc.
The wayside device may determine a distance between the first vehicle and the second vehicle, and if the distance is less than or equal to a preset distance threshold, the second vehicle is a vehicle having a communication demand with the first vehicle. When the distance to the first vehicle is small, the second vehicle and the first vehicle are relatively close to each other. The second vehicle and the first vehicle can exchange running condition information with each other, so that the second vehicle and the first vehicle can determine the running condition of the opposite side and the running environment around the opposite side, and further can judge and decide how to run safely.
In addition, the average vehicle speed of the vehicles may be preset, and if the speed of the first vehicle is greater than the average vehicle speed, it indicates that the first vehicle is traveling faster, and the first vehicle can easily catch up with the vehicle ahead, and at this time, the preset distance threshold may be increased by a certain distance value, that is, the vehicle farther away from the first vehicle is also included in the range of the vehicle having the communication demand with the first vehicle.
Optionally, the method provided by the embodiment of the present disclosure may further include: and if the driving direction of the second vehicle is the same as the driving direction of the first vehicle, transmitting the second communication key to the roadside device.
In implementation, the current roadside apparatus M may transmit all the communication keys related to the first vehicle to the other roadside apparatuses M', and the current roadside apparatus M may determine, among all the communication keys, a communication key held by a second vehicle having the same traveling direction as the first vehicle. If the driving direction of the second vehicle is different from the driving direction of the first vehicle, and it is highly likely that the second vehicle is no longer on the same road with the first vehicle for the next period of time, they no longer need to communicate, so it is possible to determine vehicles having the same driving direction as the first vehicle, and only transmit the first vehicle and the communication keys of these vehicles to the other roadside devices M'. Further, the vehicle information of the first vehicle may also be transmitted to the other roadside apparatus M'.
The other roadside apparatus M' may encrypt the communication keys of the first vehicle and the second vehicle based on the first communication key after receiving them, and transmit the encrypted communication keys of the first vehicle and the second vehicle to the first vehicle. The first vehicle may communicate with the second vehicle based on the received communication key.
The first vehicle can determine other vehicles needing to communicate, a communication key corresponding to the identification of the other vehicles is searched in the received communication key, if the communication key corresponding to the identification of the other vehicles can be searched, the communication key corresponding to the identification of the other vehicles is communicated with the other vehicles based on the communication key corresponding to the identification of the other vehicles, if the communication key corresponding to the identification of the other vehicles cannot be searched, a communication key between the first vehicle and the other vehicles is requested from the roadside device, the roadside device can assist in generating the communication key between the first vehicle and the other vehicles, and the first vehicle can communicate with the other vehicles based on the newly generated communication key.
After the first vehicle leaves the communication range of the roadside apparatus, the key material related to the first vehicle is deleted when a preset time length is reached. Further, the vehicle information of the first vehicle may also be deleted.
By the method provided by the embodiment of the invention, when a first vehicle accesses the traffic system, a first communication key is negotiated with any roadside device in the traffic system, different roadside devices can share the first communication key, and further, when the first vehicle switches to the accessed roadside device, the first vehicle does not need to negotiate the key with the newly accessed roadside device again. Thus, the computational overhead required for the key agreement operation is saved. Meanwhile, due to the fact that the time consumption of the key agreement process is long, multiple key agreement processes can be avoided through the method provided by the embodiment of the invention, the timeliness of determining the communication key of the roadside device and the first vehicle is improved, and the real-time performance of the communication process can be improved.
