怎样开启与关闭adb 的认证机制(google adb secure)
[Keyword]
adb secure , ro.adb.secure , adb RSA 指纹认证
[Solution]
MTK 版本号默认关闭adb 的地址认证机制，假设贵司须要开启，能够改动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 ==> 假设想在ENG Load新增此功能，加这行
  # 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 ==> 假设想在USER Load新增此功能，加这行
endif # !enable_target_debugging

 

而ro.adb.secure 这个system property 对于adbd 的控制点在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();
