Fig. 1 is a flow 100 of some embodiments of a gateway information transmission method of the present disclosure. The gateway information sending method comprises the following steps:
In some embodiments, an executing body (e.g., a computing device) of the gateway information sending method may determine a gateway communication information sequence corresponding to the gateway node. The gateway node may be a node for transmitting data to gateway communication information. The gateway communication may be information communicated over the target network. The gateway communication information may include: a communication identity and a starting node identity. The target network may be a communication network on the target vehicle.

The originating node may be a node that generates gateway communications. The gateway node may be, for example, a CAN (Controller Area Network ) gateway node. The target network may be a CAN network. The communication identity may be 220. The starting node identification may be a. Wherein a may characterize the body control CAN.
In some optional implementations of some embodiments, the gateway node may include: a first gateway node and a second gateway node. The first gateway node and the second gateway node may be two different gateway nodes on the target vehicle.
Optionally, the determining, by the executing body, the gateway communication information sequence corresponding to the gateway node may include the following steps:

The initial gateway communication information in the initial gateway communication information set includes: initial communication identity and communication duration. The communication duration may be a duration during which the initial gateway communication information is communicated over the target network. The target network may be a communication network on the target vehicle described above. The initial communication identity may be an identity characterizing a class of corresponding initial gateway communication information. For example, the target network may be a CAN network.
And a second step of determining a weight score corresponding to the initial gateway communication information according to the initial communication identifier and the communication duration included in the initial gateway communication information for each initial gateway communication information in the initial gateway communication information set.
Wherein the weight score may characterize the order in which the corresponding initial gateway communication information is processed by the gateway node.
Optionally, the initial gateway communication information in the initial gateway communication information set may further include: and (3) a communication period. Wherein the communication period may be used to characterize the time period during which the initiating node generates the initial gateway communication information. The communication period may be 10ms.
In some optional implementations of some embodiments, the determining, by the executing body, a weight score corresponding to the initial gateway communication information according to an initial communication identifier and a communication duration included in the initial gateway communication information may include the following substeps:
and a first sub-step of determining a preset score as a weight score corresponding to the initial gateway communication information in response to determining that the communication time period included in the initial gateway communication information is greater than or equal to a preset threshold of a communication period.
The preset threshold may be a preset threshold for defining a communication duration. The preset score may be a maximum value of a preset weight score. For example, the preset threshold may be 70%. The predetermined score may be 100.
A second sub-step of, in response to determining that the communication duration is less than a preset threshold of the communication period, performing the following processing steps:
and a first processing step of determining an information processing grade corresponding to the initial gateway communication information according to the initial communication identifier included in the initial gateway communication information.
Wherein the information processing level may characterize the size of the initial communication identity. The smaller the initial communication identification, the higher the corresponding information processing level. The executing body can determine the information processing level corresponding to the initial gateway communication information by establishing a mapping relation between the initial communication identification and the information processing level.
As an example, when the initial communication flag is 101, the corresponding information processing level is 20. When the initial communication flag is 201, the corresponding information processing level is 10.

The communication duration level may characterize a duration of the communication duration. The larger the value of the communication duration, the higher the corresponding communication duration level. For example, the executing body may determine the communication duration level corresponding to the initial gateway communication information by establishing a mapping relationship between the communication duration and the communication duration level.
As an example, when the communication duration is 10ms, the corresponding communication duration level is 10 levels. When the communication duration is 20ms, the corresponding communication duration level is 20 levels.

Wherein, the preset weight coefficient comprises: a first weight coefficient and a second weight coefficient. The first weight coefficient may be a weight coefficient corresponding to the information processing level.

As an example, the execution body may add a product of the first weight coefficient and the information processing level to a product of the second weight coefficient and the communication duration level to obtain a weight score corresponding to the initial gateway information.
The first substep-the second substep described above are taken as an invention point of an embodiment of the present disclosure, and solve the second technical problem mentioned in the background section, namely that "the processing sequence of the gateway information is sequentially determined only according to the size of the communication identifier, the situation that the communication time of part of the gateway information exceeds the communication period may occur, and further, communication delay is caused. Based on this, in order to avoid the occurrence of a communication delay, first, in response to determining that the initial gateway communication information includes a communication time period greater than or equal to a preset threshold of a communication period, a preset score is determined as a weight score corresponding to the initial gateway communication information. Therefore, the weight score corresponding to the initial gateway communication information with longer communication duration is set to be the preset score with the largest value, so that the priority processing of the initial gateway communication information with longer communication duration is realized, the condition that the communication duration of the gateway communication information exceeds a communication period is avoided, and the condition of communication delay is avoided. Then, in response to determining that the communication duration is less than a preset threshold of the communication period, performing the following processing steps: and a first processing step of determining an information processing grade corresponding to the initial gateway communication information according to the initial communication identifier included in the initial gateway communication information. And a second processing step, determining a communication duration grade corresponding to the initial gateway communication information according to the communication duration included in the initial gateway communication information. And a third processing step of determining a weight score corresponding to the initial gateway communication information according to the information processing grade, the communication duration grade and a preset weight coefficient. The initial communication identifier and the communication duration are combined to determine the weight score, so that the processing sequence of the initial gateway communication information with longer communication duration is advanced, the condition that the communication time of part of gateway information exceeds a communication period due to the fact that the processing sequence of the initial gateway communication information is determined only by the size of the initial communication identifier is avoided, and the condition of communication delay is reduced.
And thirdly, determining the processing sequence number of the initial gateway communication information corresponding to the weight score in the weight score sequence according to the obtained weight score sequence to obtain an initial gateway communication information sequence.
As an example, the executing body may determine, as the processing sequence number of the initial gateway communication information corresponding to the weight score, the position where the weight score in the obtained weight score sequence is located, and obtain the initial gateway communication information sequence.
And step four, determining the initial gateway communication information in the odd digits in the initial gateway communication information sequence as the gateway communication information corresponding to the first gateway node, and obtaining the gateway communication information sequence corresponding to the first gateway node.
As an example, there may be four pieces of initial gateway communication in the initial gateway communication sequence described above. The execution body may determine initial gateway communication information in the first bit and the third bit in the initial gateway communication information sequence as gateway communication information corresponding to the first gateway node.
And fifthly, determining the initial gateway communication information in even number in the initial gateway communication information sequence as the gateway communication information corresponding to the second gateway node, and obtaining the gateway communication information sequence corresponding to the second gateway node.
As an example, there may be four pieces of initial gateway communication in the initial gateway communication sequence described above. The execution body may determine initial gateway communication information in the second bit and the fourth bit in the initial gateway communication information sequence as gateway communication information corresponding to the second gateway node.
The first step-the fifth step are taken as an invention point of some embodiments of the present disclosure, and solve the third technical problem mentioned in the background section, that when a gateway node receives multiple gateway information at the same time, forwarding processing needs to be sequentially performed on each gateway information according to a processing sequence, so that the processing speed is slower, and the sending efficiency of the gateway information is lower. In order to improve the efficiency of transmitting gateway information, first, an initial gateway communication information set is acquired. And secondly, for each initial gateway communication information in the initial gateway communication information set, determining a weight score corresponding to the initial gateway communication information according to an initial communication identifier and a communication duration included in the initial gateway communication information. Thus, the processing order of the initial gateway communication information can be determined according to the weight score. And then, determining the processing sequence number of the initial gateway communication information corresponding to the weight score in the weight score sequence according to the obtained weight score sequence to obtain an initial gateway communication information sequence. Therefore, the processing sequence of each initial gateway communication information in the initial gateway communication information set is determined through the initial communication identifier and the communication duration included in the initial gateway communication information, and the condition of information transmission delay is avoided. And then, determining the initial gateway communication information in the odd digits in the initial gateway communication information sequence as the gateway communication information corresponding to the first gateway node, and obtaining the gateway communication information sequence corresponding to the first gateway node. And finally, determining the initial gateway communication information in even number in the initial gateway communication information sequence as the gateway communication information corresponding to the second gateway node, and obtaining the gateway communication information sequence corresponding to the second gateway node. Therefore, the initial gateway communication information is distributed through the two gateway nodes, so that the two gateway nodes can process the gateway communication information at the same time, the information processing speed is improved, and the sending efficiency of the gateway information is improved.
The computing device may be hardware or software. When the computing device is hardware, the computing device may be implemented as a distributed cluster formed by a plurality of servers or terminal devices, or may be implemented as a single server or a single terminal device. When the computing device is embodied as software, it may be installed in the hardware devices listed above.

The present invention is not particularly limited herein.
It should be understood that the number of computing devices described above is merely illustrative. There may be any number of computing devices, as desired for an implementation.
and 1021, performing anti-counterfeiting verification on the gateway communication information according to the initial identification information set and the communication identification included in the gateway communication information to generate a verification result.
In some embodiments, the executing body may perform anti-counterfeit verification on the gateway communication information according to the initial identifier set and the communication identifier included in the gateway communication information, so as to generate a verification result.
In some optional implementations of some embodiments, the executing body performs anti-counterfeit verification on the gateway communication information according to the initial identifier information set and the communication identifier included in the gateway communication information, so as to generate a verification result, and may include the following steps:
and a first step of generating a verification result representing that the gateway communication information passes the anti-counterfeiting verification in response to determining that the initial identification set meets a target condition.
The target condition is that the initial identifier set has the same initial identifier as the communication identifier included in the gateway communication information. The initial set of identifiers may be a set that includes all communication identifiers in the event that the target vehicle is not intruded by foreign information.
And a second step of generating a verification result indicating that the gateway communication information fails the anti-counterfeiting verification in response to determining that the initial identification information set does not meet the target condition.
Optionally, after the initial set of identifiers satisfies the target condition in response to determining that the initial set of identifiers satisfies the target condition, the execution body may further execute the following steps:
first, a time difference between a time when the gateway node receives the gateway communication and a time when the target communication is received is calculated.
The target gateway communication information may be the gateway communication information that is received last by the gateway node and is the same as the communication identifier and the starting node identifier included in the gateway communication information.
And a second step of generating a verification result representing that the gateway communication information passes the anti-counterfeiting verification in response to determining that the time difference is in a preset interval of a communication period corresponding to the gateway communication information.
The preset interval may be an error interval of communication duration corresponding to gateway communication information with the same two communication identifiers and the same starting node identifier. For example, the communication period may be 10ms, and the error interval may be [8ms,12ms ].
The step 1021 is an invention point of some embodiments of the present disclosure, and solves the fourth technical problem mentioned in the background section, that in the process of sending gateway information, the validity of the received gateway information is not guaranteed, which is not performed with time-efficient verification. In order to ensure the validity of the gateway information, first, a time difference between the time when the gateway node receives the above-described gateway communication information and the time when the target communication information is received is calculated. And finally, generating a verification result representing that the gateway communication information passes the time-lapse verification in response to determining that the time difference is in a preset interval of a communication period corresponding to the gateway communication information. Since the communication of gateway communication information has a certain time period, when the time difference between two gateway communication information is large compared with the communication period, there may be a problem that the gateway communication information is invalid. Therefore, the validity of the gateway communication information is determined by generating a verification result of the time-lapse verification.
Optionally, after the step 1021, the execution body may further execute the following steps:
and responding to the fact that the verification result represents that the gateway communication information does not pass the anti-counterfeiting verification, and sending intrusion prompt information to display equipment.
The intrusion prompt information indicates that the target vehicle is intruded. The display device may be a device having a display function in the target vehicle.
Step 1022, in response to determining that the verification result represents that the gateway communication information passes the anti-counterfeit verification, determining the feature parameters corresponding to the gateway communication information according to the communication identifier and the initial node identifier included in the gateway communication information.
In some embodiments, the executing body may determine, in response to determining that the verification result indicates that the gateway communication information passes the anti-counterfeit verification, a feature parameter corresponding to the gateway communication information according to a communication identifier and a start node identifier included in the gateway communication information.
In some optional implementations of some embodiments, the determining, by the executing body, a feature parameter corresponding to the gateway communication information according to a communication identifier and a start node identifier included in the gateway communication information may include the following steps:
The first step is to multiply the number of the communication identifier included in the gateway communication information with the number of the initial node identifier to obtain the target identifier value.
And secondly, carrying out feature processing on the target identification value to obtain the feature parameters corresponding to the gateway communication information.
As an example, the execution body may perform feature processing on the target identification value by using a hash algorithm, to obtain the feature parameter. For example, the hash algorithm may be an MD (Message-Digest) 5 algorithm.
In some embodiments, the executing entity may search the target routing table according to the feature parameter to determine a communication receiving node corresponding to the gateway communication information.
As an example, the execution entity may search the target routing table and determine a communication receiving node corresponding to the same value as the feature parameter, which is present in the target routing table, as the communication receiving node corresponding to the gateway communication information.
Optionally, the target routing table may be obtained by:
first, a sample communication information set is acquired.
The sample communication information set may be a set containing all gateway communication information in a case that the target vehicle is not invaded by external information. The sample communication information includes: sample identity, sample start node identity, and sample receive node identity. Wherein the sample identification may be a unique identification identifying the category of the corresponding sample communication 0. The sample start node identification may be an identification characterizing a sample start node to which the sample communication corresponds. The sample start node may be a node that generates sample communications. The sample receiving node identification may be a unique identification of the node that received the corresponding sample communication.
And a second step of determining, for each sample communication in the sample communication set, a sample feature corresponding to the sample communication according to a sample identifier and a sample start node identifier included in the sample communication.
As an example, the execution body may hash the sample identifier and the sample start node identifier by using the same hash algorithm as in the step 1022 to obtain a sample feature corresponding to the sample communication information. For example, the hash algorithm may be an MD5 algorithm.
And thirdly, taking a sample characteristic corresponding to each sample communication information in the sample communication information set as a row and taking a sample receiving node identifier included in the sample communication information as a column to obtain the target routing table.
As an example, the above-mentioned target routing table may be:
wherein, the value in the table is 0, and no mapping relation exists between the characteristic sample and the sample receiving point mark. The value in the table is 1, and the mapping relation exists between the characteristic sample and the identification of the sample receiving point. For example, the sample receiving point corresponding to sample feature 1 is identified as B. The sample receiving point corresponding to sample feature 2 is identified as C. Sample reception points corresponding to sample feature 3 are identified as a and B.
In some embodiments, the executing entity may send the gateway communication information to the communication receiving node in various ways. The communication receiving node may be a node that receives the gateway communication information.
The above embodiments of the present disclosure have the following advantages: according to the gateway information sending method, the sending efficiency of the gateway information can be improved. Specifically, the reason why the transmission efficiency of gateway information is low is that: when determining the receiving node of the gateway information, the whole routing table needs to be traversed, and the speed is low, so that the sending efficiency of the gateway information is low. Based on this, the gateway information sending method of some embodiments of the present disclosure first determines a gateway communication information sequence corresponding to a gateway node. Wherein the gateway communication information includes: a communication identity and a starting node identity. Therefore, the communication receiving node corresponding to the gateway communication information can be determined according to the communication identifier and the initial node identifier included in the gateway communication information so as to transmit the gateway communication information. Then, for each gateway communication in the gateway communication sequence, the following steps are performed: and carrying out anti-counterfeiting verification on the gateway communication information according to the initial identification information set and the communication identification included in the gateway communication information so as to generate a verification result. Therefore, the condition that the vehicle is invaded by external information is avoided by carrying out anti-counterfeiting verification on the gateway communication information. And determining characteristic parameters corresponding to the gateway communication information according to the communication identifier and the initial node identifier included in the gateway communication information in response to determining that the verification result represents that the gateway communication information passes anti-counterfeiting verification. Thus, the characteristic parameters corresponding to the gateway communication information are obtained, so that the communication receiving node corresponding to the gateway communication information is determined according to the characteristic parameters. And searching the target routing table according to the characteristic parameters to determine the communication receiving node corresponding to the gateway communication information. Therefore, only the field with the characteristic parameter is needed to be found in the target routing table, and the communication receiving point corresponding to the characteristic parameter is used as the communication receiving point corresponding to the gateway communication information. Therefore, the communication receiving node corresponding to the gateway communication information can be rapidly determined without traversing the whole routing table. And sending the gateway communication information to the communication receiving node. This improves the efficiency of transmitting gateway information.
