초록

As the usage of mobile devices becomes diverse, a number of attacks on Android also have increased. Among the attacks, Android can be compromised by flashing a new image of compromised Android Linux. In order to solve this problem, we propose SeBo (Secure Boot System) which prevents compromised Android Linux by guaranteeing secure boot environment for mobile devices based on ARM TrustZone architecture. SeBo checks the hash value of the Android Linux image before the Android Linux executes. SeBo detects all the attacks within 5 seconds. Moreover, since SeBo only trusts the Secure Bootloader from Secure World, SeBo can reduce the additional overhead of checking the Normal Bootloader from Normal World.
