Therefore, the configuration of the ECU can be dynamically added or modified according to the actual running state of the ECU without stopping and flameout or upgrading the version of the ECU.
According to the above architecture, the information configuration method provided in the embodiment of the present application is described in detail below with reference to fig. 2.

and S101, the client sends the running state information of the ECU to the server in real time.
The client runs on each ECU of the vehicle-mounted Ethernet, the server runs on the TBOX, and the client and the server can be connected with each other through a vehicle-mounted Ethernet switch. The client reports the running state information of the ECUs to the server periodically, and the running state information of the ECUs in the vehicle can represent the running state conditions of the ECUs in the vehicle, for example, the running state information can include information such as CPU utilization rate, memory utilization rate, firewall logs and host security check logs.
And S102, the server sends the ECU running state information to the cloud server.
The server establishes a Transmission Control Protocol (TCP) connection with the cloud server, and when receiving the ECU running state information sent by the client, the server reports the ECU running state information to the cloud server.

The preset configuration rule can be a configuration rule preset by a user, the cloud server determines which configuration information is issued to the client according to the running state information of the ECU, and the configuration parameters in the configuration information can be parameters for adding, modifying and deleting network layer firewall rules. For example, when the CPU utilization of an ECU in the ECU operating state information is greater than 80%, and the number of network connections from an Internet Protocol (IP) address exceeds a threshold, corresponding configuration information is obtained from a preset configuration rule, where the configuration information includes a control (iptables) command for adding a Discard (DROP) data packet from the IP.
For example, when the cloud server finds that the CPU utilization rate in the running state information of the ECU (AVM 2) is greater than 80%, finds that the number of TCP connections from the ip192.168.8.112 and the destination port 5312 is greater than a threshold according to the number of network connections collected from the AVM2, where the threshold may be set to range from 30 to 50, and the cloud server considers that the ECU is under a certain network attack, and the cloud server may send the following network-layer firewall configuration information to the ECU (AVM 2):
target ECU AVM2
Source IP 192.168.8.211
Source port any
Destination port 5312
Protocol TCP
Input interface eth1
Movement of DROP
And S104, the cloud server sends configuration information to the server.
And after determining the configuration information to be issued, the cloud server sends the configuration information to the server through the TCP connection.
S105, the server sends the configuration information to the client.
And the server analyzes the configuration information sent by the cloud server and sends the configuration information to the client of the ECU corresponding to the ECU running state information.
And S106, the client configures the ECU based on the configuration parameters in the configuration information.
And the client receives the configuration information, and adds, modifies and deletes the network layer firewall rules according to the configuration parameters in the configuration information. For example, in S103, after the ECU (AVM 2) receives the network-layer firewall configuration information sent by the cloud server, the client running on AVM2 may add the following network-layer firewall rules:
iptables-A INPUT-i eth1-s 192.168.8.211-p tcp--dport 5312-j DROP
according to the embodiment of the application, the ECU running state information is sent to the server in real time through the vehicle-mounted Ethernet switch through the client, so that the server sends the ECU running state information to the cloud server, the cloud server determines whether the configuration of the ECU needs to be dynamically updated or not based on the ECU running state information, and the configuration information is sent to the server. And then, the client receives the configuration information sent by the server through the vehicle-mounted Ethernet switch, and configures the ECU based on the configuration parameters of the ECU in the configuration information. Therefore, the configuration of the ECU can be dynamically added or modified according to the actual running state of the ECU without stopping and flameout or upgrading the version of the ECU.
Based on this, fig. 3 shows a flowchart of an information configuration method provided in an embodiment of the present application, where the information configuration method is applied to a client.

In the embodiment of the application, the electronic control unit ECU running state information is sent to the server in real time through the client, so that the server sends the ECU running state information to the cloud server, the cloud server determines whether the configuration of the ECU needs to be dynamically updated or not based on the ECU running state information, and the configuration information is sent to the server. Then, the client receives the configuration information sent by the server and configures the ECU based on the configuration parameters of the ECU in the configuration information. Therefore, the configuration of the ECU can be dynamically added or modified according to the actual running state of the ECU without stopping and flameout or upgrading the version of the ECU.
In some embodiments, the information configuration method may further include:
and sending configuration response information to the server, wherein the configuration response information can comprise the configuration parameters of the ECU, and the configuration response information is used for updating the configuration file stored by the server based on the configuration parameters of the ECU.

In some embodiments, when the server and the client successfully establish a security transport layer protocol TLS connection, the server sends configuration information analyzed by the server to the client through the vehicular ethernet switch, where the configuration information analyzed by the server may be obtained by analyzing a configuration file stored in the server, or may be obtained by analyzing configuration information issued by the cloud server by the server.
If the configuration information analyzed by the server is obtained by analyzing the configuration file stored by the server, as an example, as shown in fig. 4, S0, after the server is started, reading and analyzing the local configuration file; s1, after a client is started, establishing TCP connection with a server; s2, if ciphertext transmission is needed, the client side and the server establish TLS connection; s3, after the TLS connection is successfully established, the server sends an HELLO message to the client; s4, the client receives the HELLO message and sends an HELLO ACK message to the server to confirm that the HELLO message of the server is received; s5, the client sends a HELLO message to the server; s6, the server receives the HELLO message and sends an HELLO ACK message to the client to confirm that the HELLO message sent by the client is received; s7, the client receives the HELLO ACK message and sends a READY message to the server; s8, the server receives the READY message and sends a READY ACK message to the client to inform the client that the READY message sent by the client is received; s9, the server issues configuration information to the client according to the result of the configuration file analysis, wherein the configuration information comprises ECU network topology information, network layer firewall configuration and the like; s10, the client receives the configuration information and adds a network layer firewall rule according to the configuration information; s11, the client sends a configuration response message to the server, and the configuration response message comprises the processing result of the configuration information. If the server does not receive the configuration response message for a while, the configuration information is retransmitted to the client.
Therefore, after the server analyzes the configuration file stored in the server, the server sends the configuration information analyzed by the server to the client through the vehicular Ethernet switch under the condition that the server and the client successfully establish the TLS connection, so that the local configuration file of the server can be encrypted during transmission, and the security of interactive data is ensured.
In some embodiments, the information configuration method may further include:
sending a handshake message to a server under the condition that a TLS connection is successfully established between a client and the server;
updating the ECU state timestamp under the condition of receiving a response message sent by the server based on the handshake message;
under the condition that the ECU state timestamp exceeds the preset time and is not updated, disconnecting the TLS connection;
and sending a request for establishing the TCP connection and the TLS connection to the server, wherein the request is used for establishing the TCP connection and the TLS connection between the server and the client.
After the client and the server successfully establish the TLS connection, the client sends a handshake message to the server, where the handshake message may include a HELLO message, the response message may be a HELLO ACK message, the ECU state timestamp is updated when the response message sent by the server is received, if the preset time is not updated, the TLS connection is disconnected, and the TCP connection and the TLS connection are re-established, where the preset time may be any time preset by a user, and may be, for example, 25s.
As an example, as shown in fig. 5, a keep-alive mechanism is started between a server and a client, S0, and at a time t1, the client sends a HELLO packet to the server; s1, a server receives a HELLO message and sends HELLO ACK to a client; s2, when the client receives the HELLO ACK message sent by the server, refreshing an ECU state timestamp; s3, at the time of t1+ 5S-t 1+20S, the client sends a HELLO message to the server end every 5S, but does not receive the HELLO ACK message sent by the server all the time; s4, at the moment of t1+25S, when the time stamp of the ECU state subtracted from the current time is more than or equal to 25S, the state of the ECU is changed into a LOST (LOST) state; s5, the client disconnects the original TLS connection; and S6, the client and the server reestablish TLS connection.
In the embodiment of the application, the client sends the handshake message to the server under the condition that the client and the server successfully establish the TLS connection, the ECU state timestamp is updated under the condition that the response message sent by the server based on the handshake message is received, the TLS connection is disconnected under the condition that the ECU state timestamp exceeds the preset time and is not updated, and then the request for establishing the TCP connection and the TLS connection is sent to the server again. The keep-alive mechanism can improve the reliability and self-recovery capability of a control channel between the server and the client, and ensure real-time data transmission between the server and the client.
