摘要:	車聯網及自動駕駛車是未來的趨勢，相關的技術也在蓬勃發展，目的是幫助免於交通意外事故及方便通訊。然而，技術的發展可以解決問題，但也產生一些安全性問題。其中之一的問題是惡意的電子控制單元(ECU)可能讓車子發生不可預期的災難，導致關鍵設備無法正常使用，稱為阻斷服務攻擊;或是惡意的ECU監聽車上訊息，透過車聯網外洩，導致駭客攻擊;或是惡意的ECU假意送出惡意訊息，讓行車缺乏安全。本研究提出一個輕量級的監測系統-LWSS，在不需修改通訊協定，或影響原有運作下，透過車用控制器網路(Controller Area Net work, CAN Bus)訊息傳送過程中，建立監測系統來偵測可能惡意的ECU攻擊，並即時通知自動駕駛機制，轉成手動駕駛模式，確保行車安全，期能達到防止惡意攻擊、控制汽車的目的。;Telematics and self-driving vehicles are the future, and related tech nologies are flourishing to help prevent traffic accidents and facilitate communication. However, the development of technology can solve the problem, but also produce some safety issues. One of these problems is that a malicious electronic control unit (ECU) can cause an unpre dictable disaster in a vehicle, resulting in the failure of critical equip ment, called a Denial of Service (DoS) attack; or a malicious ECU can listen to messages in the vehicle and leak them through the vehicle net work, leading to a hacking attack; or a malicious ECU can send malicious messages under false pretenses, making the vehicle unsafe to drive. Our research proposes a lightweight monitoring system - LWSS, which does not need to modify the communication protocol or affect the original operation, and establish a monitoring system to detect possi ble malicious ECU attacks during the transmission of messages through the Controller Area Network (CAN Bus), and immediately notify the automatic driving mechanism to switch to manual driving mode to en sure the safety of driving, which can achieve the purpose of preventing malicious attacks and controlling the vehicle.
