An integrity-based mechanism for accessing keys in a mobile trusted module

The data encryption is a good method to hide the original contents of data from hackers. The main components of the cryptography are keys and passwords. In recent, to protect the keys from the hackers, the keys are stored into hardware modules that are independent on a user terminal. Otherwise, the passwords are easily exposed by a variety of password hacking techniques. Moreover, to access keys in the hardware module, users also have to input the password of key or hardware module every time. To solve these problems, we propose a mechanism to access keys in the hardware module without any password. The mechanism was implemented on our prototype with new MTM and management daemons in android environment.
