Hardware-in-the-Loop-Based Anti-theft Authentication Testing Method and System

Abstract

The invention discloses a hardware-in-the-loop-based anti-theft authentication testing method and system. The method includes: an anti-theft engine management system sends an authentication request message to an authentication simulation module, and performs a second round of encryption calculation according to a first encryption number , obtain the first encryption key; the authentication simulation module performs the first round of encryption calculation according to the random number seed, obtains the second encryption number, and compares whether the second encryption number is consistent with the first encryption number; The encrypted data is subjected to a second round of encryption calculation to obtain a second encryption key; the authentication simulation module sends an authentication response message to the anti-theft engine management system; the anti-theft engine management system compares whether the second encryption key is consistent with the first encryption key, to get the anti-theft certification result. In the hardware-in-the-loop-based anti-theft authentication testing method and system of the present invention, the anti-theft authentication logic of the EMS is tested and verified by simulating the anti-theft authentication function of the authentication module through the authentication simulation module.

Description

technical field [0001] The invention relates to the technical field of automobile electronic anti-theft, in particular to a hardware-in-the-loop-based anti-theft authentication test method and system. Background technique [0002] With the increasing number of car theft incidents, car anti-theft technology has become a hot issue that people pay attention to. Anti-theft engine management system (Engine Management System, EMS) is the core component of the engine anti-theft locking system, which is responsible for completing the anti-theft authentication between the ignition key and the engine, and its performance directly affects the engine anti-theft locking system. of normal work. [0003] The car anti-theft system includes electronic keys, electronic control circuits, alarm settings and actuators. The working principle of a typical engine anti-theft system is: by identifying the electronic key, after the key verification is passed, the authentication module and the engine...

AI Technical Summary

Problems solved by technology

Due to the limitation of the vehicle development process, the EMS anti-theft authentication logic cannot be verified until the actual vehicle loading is completed, resulting in a long overall test and certification cycle; and the anti-theft authentication error occurs on the actual vehicle, which is inconvenient to troubleshoot the cause of the problem
