Detailed ways

Exemplary embodiments of the present application are described below with reference to the accompanying drawings, which include various details of the embodiments of the present application to facilitate understanding, and should be considered as exemplary only. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present application. Also, descriptions of well-known functions and constructions are omitted from the following description for clarity and conciseness.

As shown in FIG. 1, in one embodiment, a method for processing traffic information is provided, including:

S101: Analyze the received signal to obtain traffic information carried in the signal.

S102: Search a pre-stored traffic information database according to the traffic information, and obtain a security detection result of the traffic information.

S103: In the case that the safety detection result is unsafe, determine that the traffic participant who sends the signal is an abnormal traffic participant.

In this embodiment, the above method may be executed in a security detection device. The safety detection device can be set on the roadside or in the patrol vehicle.

Signals may include vehicles transmitted using dedicated short-range communication technology (DSRC, Dedicated Short Range Communication), cellular link communication technology (LTE-V-Cell), short-range direct link communication technology (LTE-V-Direct), 5G communication technology, etc. Use wireless communication (V2X, Vehicle to Everything) signal.

Traffic information sent by traffic participants is carried in the V2X signal. Traffic participants may include vehicles and roadside traffic equipment.

The traffic information sent by the vehicle may include driving information of the vehicle, such as vehicle speed information, vehicle location information, vehicle size information and other different types of information.

Roadside traffic devices may include traffic lights, roadside speed limit devices, parking metering devices, and the like. The traffic information sent by the roadside traffic equipment may include different types of information, such as the status of traffic lights, the remaining time of the current light status, and speed limit information on the current road section. The types of the above traffic information can be divided according to the "Application Layer and Application Data Interaction Standard of the Vehicle Communication System of the Cooperative Intelligent Transportation System".

In addition, the traffic information may also include the serial number of the traffic participant, the serial number of the certificate, and the like. The certificate can be issued by the certificate management department, such as the traffic control department and other authoritative organizations. Each legal certificate has its corresponding certificate serial number. Traffic participants can use certificates to sign traffic information.

A traffic information database may be stored in the safety detection device, and the traffic information database may be downloaded from the cloud (server) or pre-stored. The traffic information database stores the safe value range of different types of traffic information, the safe value range of the value change, and the certificate serial number of the legal certificate. For example, the safe value range of the change period of the traffic lights is between 10 seconds and 90 seconds, the safe value range of the road speed limit is between 40km/h and 120km/h, and the safe value of the time change of the two traffic lights before and after. Values range from 1 to 5 seconds, etc. The traffic information database is used to provide reference data for the safety detection of traffic information.

The safety detection equipment analyzes the received signal, and can obtain the traffic information carried in the signal. The security detection device searches the traffic information database according to the different types of information parsed, so as to perform security detection.

Combined with the application scenario shown in Figure 2. Roadside traffic equipment includes speed limiters and traffic lights. The safety detection device can be installed on the roadside or in the patrol vehicle, so as to detect the signals sent by the roadside traffic device and the vehicle running on the road.

Taking a speed-limiting device as an example, the speed-limiting device broadcasts a speed-limiting signal, which contains the serial number, certificate serial number, traffic information type (speed-limiting) and data corresponding to key fields (speed-limiting data) of the speed-limiting device. and other information. For example, when the information broadcast by the speed-limiting device is between 40km/h and 120km/h, it can be confirmed that the speed-limiting device has passed the safety test. When the speed limit data is not between 40km/h and 120km/h, for example, the information broadcast by the speed limit device is 200km/h or 5km/h, it can be confirmed that the speed limit device is an abnormal traffic participant. Abnormal traffic participants may include that the speed limiting device may have been hacked, or that the speed limiting device is a fake device, etc.

In addition, whether the speed-limiting device is an abnormal traffic participant can also be confirmed by checking the validity of the certificate serial number. For example, the legal certificate serial number is stored in the traffic information database. The security detection equipment can obtain the certificate serial number from the traffic information. The obtained certificate serial number can be verified by using the legal certificate serial number, so as to determine whether the speed-limiting device is an abnormal traffic participant.

Through the above solution, the security of the traffic information is detected by the security detection device. When the detection result is unsafe, it can be detected and processed in time to effectively deal with the risk of traffic information being attacked.

As shown in FIG. 3, in one embodiment, step S102 includes:

S1021: Extract key fields of the traffic information and first numerical values corresponding to the key fields.

S1022: Acquire the safe value range of the first value corresponding to the key field in the traffic information database.

S1023: In the case that the first numerical value exceeds the safe value range of the first numerical value, determine that the safety detection result is unsafe.

Key fields in traffic information can be extracted using techniques such as semantic recognition. For example, "speed limit", "current vehicle speed", etc.

Each key field may correspond to a numerical value, that is, the first numerical value. For example: the key field is "current vehicle speed", and the corresponding first value is 200km/h.

According to the key field, the traffic information database is queried to obtain the safe value range of the first value corresponding to the vehicle speed. For example, the safe value range of the vehicle speed recorded in the traffic information database is 60km/h～120km/h. It is necessary to confirm whether the first value of 200km/h is within the safe value range. In the above-mentioned embodiment, it can be determined that the traffic participant whose current vehicle speed is 200 km/h is an abnormal traffic participant.

For another example, the key field is "red light duration", and the corresponding value is 35 seconds.

According to the key field, the traffic information database is queried to obtain the safe value range of the value corresponding to the red light duration. For example, the safe value range of the duration of the red light recorded in the traffic information database is 30 seconds to 90 seconds. It is necessary to confirm whether 35 is within the safe value range. In the above embodiment, it may be determined that it is safe to issue a traffic signal including a red light for a duration of 35 seconds.

Through the above solution, the security is judged by using the first value corresponding to the key field in the traffic information, and if it exceeds the security range, it can be determined to be attacked. As a result, even if an attacker uses a real certificate, he or she can be identified as insecure because the range of values in their traffic information exceeds the limit.

As shown in FIG. 4 , in an embodiment, in the case that the signal is a signal received multiple times, step S102 further includes:

S1024: Determine the amount of change of the first value in the traffic information obtained by analyzing the two adjacent signals received.

S1025: Obtain the safe value range of the variation in the traffic information database.

S1026: In the case that the change amount exceeds the safe value range of the change amount, determine that the safety detection result is unsafe.

The wireless communication signal for the vehicle may be a continuous signal, for example, a traffic signal will continuously broadcast the signal continuously, for example, it may broadcast once every 1 second.

Therefore, the safety detection device can receive the vehicle wireless communication signal many times. The key field and the corresponding first value can be parsed from each received signal. For example, the key field is "red light duration", and the first value parsed and extracted from two adjacent received signals is 35 seconds and 10 seconds, respectively. From this, it can be determined that the amount of change of the first value for two consecutive times is 25 seconds.

According to the key fields, the traffic information database is queried to obtain the safe value range corresponding to the change in the duration of the red light. For example, the safe value range corresponding to the change in the duration of the red light is 1 second to 5 seconds. In the case that the variation exceeds the safe value range, it is determined that the safety detection result is unsafe, that is, the traffic signal is determined to be an abnormal traffic participant.

Through the above solution, even if the first value is within the safe value range, it can be determined to be attacked when it mutates.

As shown in Figure 5, in one embodiment, the above method further includes:

S1011: Acquire certificate information from traffic information.

S1012: Determine the traffic participant who sends the signal according to the certificate information.

S1013: In the case that the traffic participant is an abnormal traffic participant, report the information of the abnormal traffic participant.

After the safety detection device receives the signal, it can obtain the traffic information by analyzing the signal. The traffic information can be the information signed by the certificate, so after the traffic information is correctly signed, the certificate serial number can be obtained. The certificate serial number obtained after correct signature verification can be verified by using the legal certificate serial number stored in the traffic information database. In addition, the certificate information may also be certificate plaintext, certificate password, and the like.

The signalling traffic participant can be identified on the basis of the certificate serial number. The legal certificate serial number is issued by the authority to the traffic participants, and the traffic participant who sends the signal can be determined through the certificate serial number. When the safety detection result is unsafe, it is determined to be an abnormal traffic participant.

Send the information about the abnormal traffic participants who signaled to the cloud (server). The relevant information can be certificate serial number, serial number, etc. Subsequent processing can be performed by the cloud (server) abnormal traffic participants, such as reporting to the certificate issuing authority to cancel their certificates, or broadcasting warnings to other traffic participants.

In the above manner, an insecure device can be locked out by using the certificate information, thereby facilitating subsequent processing of the device.

As shown in Figure 6, the present application provides a method for processing traffic information, comprising the following steps:

S601: Send a traffic information database to a security detection device, where the traffic information database is used to provide reference data for security detection of traffic information.

S602: Send the received information of the abnormal traffic participant to the target user.

The above steps can be performed by the cloud (server). The cloud (server) periodically sends the traffic information database to the security detection device, for example, the range of data update can be used as a condition for triggering the regular sending. The traffic information database stores the safe value range of the first data corresponding to different types of traffic information, the safe value range of the first data variation in two consecutive times, and the certificate serial number of the legal certificate. It is used to provide reference data for the security detection of traffic information.

When the safety detection device determines the abnormal traffic participant, it will report the information of the abnormal traffic participant. From this, the cloud (server) can obtain the information of the abnormal traffic participants. For example, it can be a certificate serial number, a serial number, and the like.

The cloud (server) can send the received information of abnormal traffic participants to the target user. The target user may be other traffic participants, such as vehicles near the abnormal traffic participants, and the above vehicles are informed that there are abnormal traffic participants. Alternatively, the target user may also be a certificate authority, so that the certificate issuing authority invalidates the certificate of the abnormal traffic participant.

Through the above solution, after the abnormal traffic participants are determined by using the traffic information, they can be dealt with in time. Effectively deal with the risk of traffic information being attacked.

Send information about abnormal traffic participants to the certificate authority and/or normal traffic participants.
