论文摘要
汽车市场对于网络攻击的盈利是有利可图的。汽车上安装的电子控制单元（ECU）通常在关键和敌对的环境中运行。因此，汽车制造商和政府都支持减轻汽车领域的风险和威胁的举措。本地互连网络（LIN）是汽车字段中最常用的通信协议之一。当今的LIN总线只有一些轻型安全机制可以通过消息身份验证代码（MAC）确保完整性。但是，几个限制的局限性使得将这些技术应用于Lin网络充满挑战，使几辆车辆仍然没有受到保护。本文介绍了LIN多路复用MAC（LINMM），这是一种使用标准LIN通信将信号调制到多重MAC数据的新方法。 Linmm允许传输MAC有效载荷，并与标准LIN协议的所有版本保持后卫兼容性。
The automotive market is profitable for cyberattacks with the constant shift toward interconnected vehicles. Electronic Control Units (ECUs) installed on cars often operate in a critical and hostile environment. Hence, both carmakers and governments have supported initiatives to mitigate risks and threats belonging to the automotive domain. The Local Interconnect Network (LIN) is one of the most used communication protocols in the automotive field. Today's LIN buses have just a few light security mechanisms to assure integrity through Message Authentication Codes (MAC). However, several limitations with strong constraints make applying those techniques to LIN networks challenging, leaving several vehicles still unprotected. This paper presents LIN Multiplexed MAC (LINMM), a new approach for exploiting signal modulation to multiplex MAC data with standard LIN communication. LINMM allows for transmitting MAC payloads, maintaining fullback compatibility with all versions of the standard LIN protocol.
