Abstract

An identity authentication system for a vehicle comprises a vehicle door near-field recognition device and a vehicle starting near-field recognition device. The vehicle door near-field recognition device comprises an SE chip, a vehicle door MCU chip and a vehicle door NFC chip, and the vehicle starting near-field recognition device comprises a starting MCU chip and a starting NFC chip. The NFC chip with a short-distance communication function is used so that communication is prevented from being stolen, and door opening and starting functions are prevented from being authenticated at the same time; an SE chip with an authentication algorithm is adopted so that the information of a non-contact card or a car key supporting an NFC interface mobile equipment form cannot be illegally forged; the SE chip is adopted to realize safe identity authentication, and a trusted computing environment is realized for authentication information data of NFC communication; and two or more module modes share one SE chip so that only the content of one SE chip needs to be modified when information stored in the SE chip is modified, and a modification range is reduced.

Description

technical field [0001] The present invention relates to the technical field of information security, and more particularly, to a vehicle identity authentication system and method. Background technique [0002] With the development of modern society, people's living standards are constantly improving, and the number of vehicles in society is also increasing. In addition to mechanical car keys, current vehicles are often equipped with keyless entry systems and keyless start systems. The user can open the door and start the vehicle with the configured smart key. When using the smart key to open the car door, identity authentication is required once, and identity authentication is required again when starting the vehicle. The entire operation needs to complete identity authentication twice. [0003] The existing smart key uses wireless communication technology to communicate with the vehicle system, and there is a risk of information relay attack. When the smart key is away f...
