# Hardware / Embedded Interface Security
## 适用场景
- UART / JTAG / SWD 调试口发现
- 启动日志、root shell、引导打断
- 配合拆机提取 Flash
- 安全启动/加密 Flash 的可行性评估（非破坏性优先）
## 工作流
```text
□ 拆解授权设备；拍照标注测试点
□ 万用表找 GND/VCC/TX/RX；逻辑电平 1.8/3.3/5V
□ USB-TTL 只读日志；记录波特率
□ JTAG：枚举 IDCODE；评估是否锁定
□ 提取镜像 → 交接 firmware-pentest / ghidra
```
## 工具链
| 工具 | 用途 |
|------|------|
| USB-TTL / logic analyzer | UART |
| J-Link / CMSIS-DAP | 调试 |
| bus pirate / flipper（实验室） | 多协议 |
| binwalk / flashrom | 提取 |
