If the items below still feel unfamiliar, you usually get a better result by preparing first instead of rushing in.
C语言
SM2密码算法
数字签名与验签
嵌入式软件移植
NXP S32K148开发板
MISRA C与CERT C规范
The real friction is usually not library usage. It is validation, time allocation, and task framing.
难点不只是实现可用的SM2，而是把算法作为软件库正确移植进Crypto协议栈，并在指定ECU上复现、验证和优化。作品还要面对代码相似度、编码安全规范与漏洞扫描要求，同时决赛会比较集成耗时、资源消耗和运行性能；参赛作品需签署CLA并向“小满”项目贡献。
