- [esp32]secure boot v1 및 flash encryption 목차
저는 esp-idf 4.3을 사용하고 있습니다.
secure boot 및 flash encryption의 절차를 정리해 두었습니다.
1. menuconfig 수정
> Security features -> Enable hardware Secure Boot in bootloader
Secure bootloader mode를 Reflashable로 변경
Sign binaries during build(NEW)
-> secure_boot_signing_key.pem 이름을 그대로 사용
Enable flash encryption on bootloader
-> Enable usage mode(Development(Not SECURE)
> bootloader config->bootloader log verbosity(error)
> Partition Table -> Offset of partition table을 0x10000으로 변경
2. PEM 파일 생성
bsp/esp32/components/esptool_py/esptool /python espsecure.py generate_signing_key secure_boot_signing_key.pem
생성한 후 secure_boot_signing_key.pem 파일을
apps/esp32/light_example/build/ 아래에 저장한다
3. bootloader 관련 파일 생성 (to build a Secure Boot enabled bootloader.)
python build.py esp32 light_example bootloader 수행
출력 위치는 apps/esp32/light_example/build/bootloader/
생성된 파일은
1) secure-bootloader-key-256.bin
2) bootloader.bin
3) bootloader-reflash-digest.bin (To reflash the bootloader after initial flash)
4. efuse burning
1) Burn secure boot key to efuse using
bsp/esp32/components/esptool_py/esptool/secure_boot$ python ../espefuse.py --port /dev/ttyUSB0 burn_key secure_boot_v1 secure-bootloader-key-256.bin
5. 최초 flash write
1) bootloader-reflash-digest.bin
python ../esptool.py -p /dev/ttyUSB0 -b 460800 --before default_reset --after hard_reset --chip esp32 write_flash --flash_mode dio --flash_size detect --flash_freq 40m 0x00 bootloader-reflash-digest.bin
2) bootloader
python ../esptool.py -p /dev/ttyUSB0 -b 460800 --before default_reset --after hard_reset --chip esp32 write_flash --flash_mode dio --flash_size detect --flash_freq 40m 0x1000 bootloader.bin
3) python build.py esp32 light_example flash monitor
( Run idf.py flash to build and flash the partition table and the just-built app image.)
( idf.py flash doesn’t flash the bootloader if Secure Boot is enabled.)
6. 이후 flash write
1) bootloader 및 bootloader-reflash-digest.bin를 다시 다운로드하는 경우
1) bootloader-reflash-digest.bin
python ../esptool.py -p /dev/ttyUSB0 -b 460800 --before default_reset --after hard_reset --chip esp32 write_flash --flash_mode dio --flash_size detect --flash_freq 40m --encrypt 0x00 bootloader-reflash-digest.bin
2) bootloader
python ../esptool.py -p /dev/ttyUSB0 -b 460800 --before default_reset --after hard_reset --chip esp32 write_flash --flash_mode dio --flash_size detect --flash_freq 40m --encrypt 0x1000 bootloader.bin
python build.py esp32 light_example encrypted-flash monitor
python ../esptool.py -p /dev/ttyUSB0 -b 460800 --before default_reset --after no_reset --chip esp32 write_flash --flash_mode dio --flash_size detect --flash_freq 40m --encrypt 0x10000 apps/esp32/light_example/build/partition_table/partition-table.bin 0x19000 apps/esp32/light_example/build/ota_data_initial.bin 0x20000 apps/esp32/light_example/build/light_example.bin
참고 1) 응용 프로그램이 정상적으로 Secure Boot에 맞게 Sign 되었는지 확인 명령(espsecure.py verify_signature --version 1 --keyfile apps ... )
python bsp/esp32/components/esptool_py/esptool/espsecure.py verify_signature --version 1 --keyfile apps/esp32/light_example/secure_boot_signing_key.pem apps/esp32/light_example/build/light_example.bin
