[Description]
怎樣開啟與關閉adb 的認證機制(google adb secure)
[Keyword]
adb secure , ro.adb.secure , adb RSA 指紋認證
[Solution]
MTK 版本號默認關閉adb 的地址認證機制，假設貴司須要開啟，能夠改動alps/build/core/main.mk

ifeq (true,$(strip $(enable_target_debugging)))
  # Target is more debuggable and adbd is on by default
  ADDITIONAL_DEFAULT_PROPERTIES += ro.debuggable=1
  ADDITIONAL_DEFAULT_PROPERTIES += ro.adb.secure=1 ==> 假設想在ENG Load新增此功能，加這行
  # Include the debugging/testing OTA keys in this build.
  INCLUDE_TEST_OTA_KEYS := true
else # !enable_target_debugging
  # Target is less debuggable and adbd is off by default
  ADDITIONAL_DEFAULT_PROPERTIES += ro.debuggable=0
  ADDITIONAL_DEFAULT_PROPERTIES += ro.adb.secure=1 ==> 假設想在USER Load新增此功能，加這行
endif # !enable_target_debugging

 

而ro.adb.secure 這個system property 對於adbd 的控制點在alps/system/core/adb/adb.c 中的
property_get("ro.adb.secure", value, "0");
auth_enabled = !strcmp(value, "1");
if (auth_enabled)
    adb_auth_init();
