Abstract EN
Android system has been one of the main targets of hacker attacks for a long time.
At present, it is faced with security risks such as privilege escalation attacks, image tampering, and malicious programs.
In view of the above risks, the current detection of the application layer can no longer guarantee the security of the Android system.
The security of mobile terminals needs to be fully protected from the bottom to the top, and the consistency test of the hardware system is realized from the hardware layer of the terminal.
However, there is not a complete set of security measures to ensure the reliability and integrity of the Android system at present.
Therefore, from the perspective of trusted computing, this paper proposes and implements a trusted static measurement method of the Android system based on TrustZone to protect the integrity of the system layer and provide a trusted underlying environment for the detection of the Android application layer.
This paper analyzes from two aspects of security and efficiency.
The experimental results show that this method can detect the Android system layer privilege escalation attack and discover the rootkit that breaks the integrity of the Android kernel in time during the startup process, and the performance loss of this method is within the acceptable range.
