[0084] see Figure 7 , Figure 7 The first embodiment of the MAC address-based allocation and secure communication system 100 of the present invention is shown, which includes:

[0085] The offline server 1 is used to construct a MAC address table according to the vehicle identification code and the MAC address segment assigned by the OEM and synchronize the MAC address table to the cloud server. The MAC address table includes the vehicle identification code of the target vehicle, the target vehicle The corresponding relationship between the ECU module and the MAC address, the MAC address corresponds to the ECU module one by one. It should be noted that when assigning MAC addresses to the ECU modules of the target vehicle, it is necessary to ensure that the MAC addresses of each ECU module of different vehicles of the same model are different, that is, to ensure that there is a one-to-one correspondence between the ECU modules and the MAC addresses and that each ECU module ha...

Abstract

The invention discloses an MAC address-based distribution method, which comprises the following steps that: a detection device acquires an MAC address table of a target vehicle from an offline serveraccording to a vehicle identification code, the MAC address table comprises a corresponding relationship among the vehicle identification code of the target vehicle, ECU modules of the target vehicleand MAC addresses, and the MAC addresses are in one-to-one correspondence with the ECU modules; the detection device allocates an MAC address to a target vehicle ECU module according to the MAC address table. The invention further discloses an MAC address-based secure communication method, a detection device, a gateway module and an MAC address-based allocation and secure communication system. According to the method disclosed in the invention, the MAC address is uniquely allocated to the ECU module of the whole vehicle, and therefore the information security of vehicle-mounted Ethernet communication can be effectively ensured.

Description

technical field [0001] The invention relates to the technical field of vehicle Ethernet security, in particular to a MAC address-based allocation method, a MAC address-based secure communication method, a detection device, a gateway module, and a MAC address-based allocation and secure communication system. Background technique [0002] With the rapid development of in-vehicle network communication technology, the application of in-vehicle Ethernet in automobiles is becoming more and more extensive. Entertainment systems and intelligent driving systems have gradually switched to in-vehicle Ethernet for signal transmission. Therefore, in order to ensure the Communication information security, the gateway needs to add security policies for data forwarding. [0003] At present, the gateway mainly realizes terminal access by setting a white list. For example, the prior art discloses a method of using a home gateway to prevent wireless network scraping, which implements device a...
