Research on the Secure Boot Scheme of Automotive MCU
摘要
Abstract
With the development of Internet technology,attacks against vehicles occur frequently.Hackers can flash malware into the automotive MCU to maliciously control the vehicle or steal important information.For the above attack scenarios,it is necessary to add secure boot to the automotive MCU.Functions are protected to ensure that only legitimate software can be run.This paper first conducts an in-depth study of the current mainstream secure boot schemes,summarizes their performance and shortcomings in terms of safety,stability,and low time-consuming,and then proposes an optimization scheme for low-time-consuming performance,and finally verified the feasibility and effectiveness of the optimization scheme through the built physical system.The results show that sampling verification and compilation optimization can protect as much important code as possible while satisfying the time-consuming verification.关键词
