Allocation method, secure communication method, detection device, gateway module and system

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...
