车内组的密钥分配
摘要：
本公开涉及一种车内组的密钥分配。一种网关包括实现硬件随机数生成器的硬件安全模块(HSM)和维护密钥注入状态表(KIST)的非暂时性存储器。所述网关被配置为：响应于从生产线下线(EOL)工具接收到用于开始密钥分配的触发，将使用硬件随机数生成器生成的密钥分配给多个电子控制单元(ECU)；响应于完成密钥分配，将密钥注入状态表发送到生产线下线工具。响应于通过车辆总线接收到车辆电子控制单元的唯一标识符(UID)，将使用硬件随机数生成器生成的密钥按照加密消息发送到所述电子控制单元。响应于第二加密消息中的来自所述电子控制单元的成功指示，更新密钥注入状态表，以指示所述密钥被应用于所述电子控制单元。
摘要（英）：

The present invention discloses an in-vehicle group key distribution. A gateway includes a hardware security module (HSM) implementing a hardware random number generator and a non-transitory memory maintaining a key injection status table (KIST). The gateway is programmed to distribute keys generated using the random number generator to a plurality of electronic control units (ECUs) responsive toa trigger to begin key distribution received from an end-of-line (EOL) tool, and send the KIST to the EOL tool responsive to completion of the key distribution. A key generated using a hardware randomnumber generator is sent in an encrypted message to a vehicle electronic control unit (ECU), responsive to receiving a unique identifier (UID) of the ECU over a vehicle bus. Responsive to an indication of success from the ECU in a second encrypted message, a key injection status table (KIST) is updated to indicate that the key was applied to the ECU.
