Detailed Description
The following description of the exemplary embodiments of the present application, taken in conjunction with the accompanying drawings, includes various details of the embodiments of the application for the understanding of the same, which are to be considered 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 in 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: and analyzing the received signals to obtain the traffic information carried in the signals.
S102: and searching a pre-stored traffic information database according to the traffic information to obtain a safety detection result of the traffic information.
S103: and under the condition that the safety detection result is unsafe, determining that the traffic participant sending the signal is an abnormal traffic participant.
The method described above in this embodiment may be performed in a security detection device. The safety detection equipment can be arranged on the road side and also can be arranged in the inspection vehicle.
The signal may include a vehicular wireless communication (V2X) signal transmitted using Dedicated Short Range Communication (DSRC), cellular link communication (LTE-V-Cell), Short range Direct link communication (LTE-V-Direct), 5G communication, and the like.
The V2X signal carries traffic information sent by the traffic participants. The traffic participants may include vehicles and roadside traffic devices.
The traffic information transmitted by the vehicle may include driving information of the vehicle, such as vehicle speed information, vehicle position information, vehicle size information, and other different types of information.
The roadside traffic equipment may include traffic signal lights, roadside speed limit equipment, parking billing equipment, and the like. The traffic information sent by the road side traffic equipment can comprise different types of information such as the state of a traffic light, the remaining time of the current light state, the speed limit information of the current road section and the like. The types of the traffic information can be divided according to an application layer and an application data interaction standard of the vehicular communication system of the cooperative intelligent transportation system.
In addition, the traffic information may include serial numbers, certificate serial numbers, and the like of the traffic participants. The certificate may be issued by a certificate management part, such as an authority like a department of delivery. Each legal certificate has its corresponding certificate serial number. The traffic participant may sign the traffic information with the certificate.
A traffic information database may be stored in the security detection device, and the traffic information database may be downloaded from a cloud (server) or may be pre-stored. The traffic information database stores the safety value range of different types of traffic information, the safety value range of numerical variation, the certificate serial number of a legal certificate and the like. For example, the safety value range of the change period of the traffic lights is between 10 seconds and 90 seconds, the safety value range of the road speed limit is between 40km/h and 120km/h, the safety value range of the time change amount of the traffic lights in two times before and after is between 1 second and 5 seconds, and the like. The traffic information database is used for providing reference data for the safety detection of the traffic information.
The safety detection equipment analyzes the received signal, and can obtain the traffic information carried in the signal. And the safety detection equipment queries in a traffic information database according to the analyzed information of different types so as to perform safety detection.
In connection with the application scenario shown in fig. 2. The roadside traffic equipment comprises speed limiting equipment and traffic signal lamps. The safety detection device may be provided on the road side or in the inspection vehicle to detect signals emitted by the road side traffic devices and vehicles traveling on the road.
Taking the speed limiting device as an example, the speed limiting device broadcasts a speed limiting signal, and the signal contains information such as a serial number, a certificate serial number, a traffic information type (speed limit) and data (speed limiting data) corresponding to a key field of the speed limiting device. For example, in the case where the information broadcast by the speed limiting device is between 40km/h and 120km/h, it is possible to confirm that the speed limiting device passes the security check. And when the speed limit data is not between 40km/h and 120km/h, for example, the information broadcast by the speed limit equipment is 200km/h or 5km/h, the speed limit equipment can be confirmed to be an abnormal traffic participant. The abnormal traffic participant may include that the speed limiting device may have been hacked, or that the speed limiting device is a forged device, etc.
In addition, whether the speed limiting equipment is an abnormal traffic participant or not can be confirmed by detecting the validity of the certificate serial number. For example, a traffic information database stores therein a legal certificate serial number. The security detection device may obtain the certificate serial number from the traffic information. The obtained certificate serial number can be verified by utilizing the legal certificate serial number, so that whether the speed limiting equipment is an abnormal traffic participant or not is determined.
Through the scheme, the safety of the traffic information is detected through the safety detection equipment. And under the condition that the detection result is unsafe, the traffic information can be timely found and processed, and the risk that the traffic information is attacked can be effectively responded.
As shown in fig. 3, in one embodiment, step S102 includes:
s1021: and extracting a key field of the traffic information and a first numerical value corresponding to the key field.
S1022: and acquiring a safety value range of a first numerical value corresponding to the key field in a traffic information database.
S1023: and determining that the safety detection result is unsafe under the condition that the first value exceeds the safety value range of the first value.
The key fields in the traffic information can be extracted by utilizing technologies such as semantic recognition and the like. Such as "speed limit", "current vehicle speed", etc.
Each key field may correspond to a value, i.e., a first value. For example: the key field is "current vehicle speed", and the corresponding first numerical value is 200 km/h.
And inquiring in a traffic information database according to the key field to obtain a safety value range of the first numerical value corresponding to the vehicle speed. For example, the safe value range of the vehicle speed is recorded in the traffic information database to be 60 km/h-120 km/h. It is necessary to confirm whether the first value of 200km/h is within the safe value range. In the above embodiment, it may be determined that the traffic participant who includes the current vehicle speed of 200km/h is an abnormal traffic participant.
As another example, the key field is "red light duration" and the corresponding value is 35 seconds.
And inquiring in a traffic information database according to the key field to obtain a safety value range of the value corresponding to the red light duration. For example, the safety value range of the red light time length is recorded in the traffic information database and is 30 seconds to 90 seconds. It is necessary to confirm 35 whether it is within a safe range of values. In the above embodiment, it may be determined that it is safe to emit a traffic signal light including a red light for a period of 35 seconds.
By the scheme, the safety is judged by utilizing the first numerical value corresponding to the key field in the traffic information, and if the first numerical value exceeds the safety range, the attack can be determined. Thus, even if an attacker uses a real certificate, insecurity can be identified because the numerical range in the traffic information exceeds the standard.
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: the variation of the first value in the traffic information analyzed from the signals received at two adjacent times is determined.
S1025: and acquiring the safe value range of the variable quantity in the traffic information database.
S1026: and determining that the safety detection result is unsafe under the condition that the variation exceeds the safety value range of the variation.
The wireless communication signal for the vehicle may be a continuous signal, such as a continuous broadcast signal that may be uninterrupted by a traffic light, and may be broadcast 1 time every 1 second, for example.
Therefore, the safety detection device can receive the wireless communication signal for the vehicle multiple times. The key field and the first value corresponding thereto can be parsed from each received signal. For example, the key field is "red light duration", and the first values parsed and extracted from the signals received twice in the vicinity are 35 seconds and 10 seconds, respectively. It can thus be determined that the first value changes 25 seconds two times in a row.
And inquiring in a traffic information database according to the key field to obtain a safety value range corresponding to the red light time length variation. For example, the safety value range corresponding to the red light time length variation is 1 second to 5 seconds. And under the condition that the variation exceeds the safety value range, determining that the safety detection result is unsafe, namely determining that the traffic signal lamp is an abnormal traffic participant.
Through the scheme, even if the first value is in the safe value range, the attack can be determined under the condition that the first value is mutated.
As shown in fig. 5, in one embodiment, the method further comprises:
s1011: certificate information is obtained from the traffic information.
S1012: and determining the traffic participant who sends the signal according to the certificate information.
S1013: and reporting the information of the abnormal traffic participants under the condition that the traffic participants are abnormal traffic participants.
After the safety detection equipment receives the signals, the traffic information can be obtained by analyzing the signals. The traffic information can be information signed by a certificate, so that the serial number of the certificate can be obtained after the traffic information is correctly signed. The certificate serial number obtained after the correct signature verification can be verified by utilizing the legal certificate serial number stored in the traffic information database. In addition, the certificate information may also be certificate plaintext, certificate password, or the like.
The signaling traffic participant can be determined from the certificate serial number. The legal certificate serial number is issued to the traffic participants by an authority, and the traffic participants who send signals can be determined through the certificate serial number. And determining the abnormal traffic participant when the safety detection result is unsafe.
And sending the related information of the abnormal traffic participant sending the signal to the cloud (server). The related information may be a certificate serial number, a serial number, etc. The abnormal traffic participants can be processed by the cloud (server), for example, the abnormal traffic participants are reported to a certificate issuing organization to cancel the certificate, or early warning broadcast is performed to other traffic participants.
By the mode, the unsafe equipment can be locked by utilizing the certificate information, so that the subsequent processing of the equipment is facilitated.
As shown in fig. 6, the present application provides a method for processing traffic information, including the following steps:
s601: and sending a traffic information database to the safety detection equipment, wherein the traffic information database is used for providing reference data for the safety detection of the traffic information.
S602: and sending the received information of the abnormal traffic participants to the target user.
The above steps may be performed by a cloud (server). The cloud (server) periodically sends the traffic information database to the security detection device, for example, the amplitude of data update may be used as a condition for triggering the periodic sending. The traffic information database stores the safety value range of the first data corresponding to different types of traffic information, the safety value range of the variable quantity of the first data in two adjacent times, the certificate serial number of a legal certificate and the like. For providing reference data for security detection of traffic information.
And when the safety detection equipment determines the abnormal traffic participants, reporting the information of the abnormal traffic participants. Therefore, the cloud (server) can acquire the information of the abnormal traffic participants. For example, a certificate serial number, etc.
The cloud (server) can send the received information of the abnormal traffic participants to the target user. The target user may be another traffic participant, such as a vehicle in the vicinity of the abnormal traffic participant, informing the vehicle of the existence of the abnormal traffic participant. Alternatively, the target user may be a certificate authority, so that the certificate issuing authority invalidates the certificate of the abnormal traffic participant.
By the scheme, after the abnormal traffic participants are determined by the traffic information, the abnormal traffic participants can be processed in time. Effectively deal with the risk that the traffic information is attacked.
