控制器局域网（CAN）是一种主要的车载网络，其安全性要求很高。已经提出了许多检测未授权数据传输的方法，例如异常检测和误用检测。然而，它们都没有防止未经授权的数据传输本身的能力。在本文中，我们提出了一种新的方法，实现预防以及检测。我们的方法可以有效地实现与电子控制单元的当前架构的最小变化。该方法即使在具有通过网关互连的多个总线的CAN中也有效。
There is a strong demand for the security of Controller Area Network (CAN), a major in-vehicle network. A number of methods to detect unauthorized data transmission, such as anomaly detection and misuse detection, have already been proposed. However, all of them have no capability of preventing unauthorized data transmission itself. In this paper, we propose a novel method that realizes the prevention as well as detection. Our method can be effectively implemented with minimal changes in the current architecture of Electronic Control Unit. The method works even in a CAN with multiple buses interconnected by gateways.
