This isn’t because there’s no way to secure CAN communications, mind you. A strong implementation (and in fact, the industry standard) would involve two CAN security features, in addition to the implementation of firmware-level unique keys and ECDSA/RSA firmware signing. UDS Service 0x29 (introduced in ISO 14229-1:2020) uses asymmetric PKI-based certificate exchange for user authentication, and AUTOSAR SecOC for per-message authentication and freshness validation, preventing replay attacks. While these modifications would add some additional time to the firmware write operations, the Arm Cortex-M4 core included in the ECU’s XMC4500 is very efficient at cryptographic functions and the total delta would likely be only about 6 seconds.4 5 6

我非常喜欢FluxCD的模块化架构，不同的控制器处理协调过程的不同部分。源控制器确保OCI或Git源与磁盘上的内容一致，Kustomize控制器确保部署在集群上的清单与源控制器暴露的内容匹配，等等。这使得你可以轻松地选择适合你设置的部分。
