- The purpose of this study is to suggest a solution to recently emerging security threats to mobile devices and enable users to use mobile services in a secure manner. To that end, this paper presents the design and implementation method for a hardware security chip required for providing advanced mobile security services. The proposed method could be the fastest and most efficient approach among various approaches. This study implements a Mobile Trusted Module (MTM) chip as a hardware security chip and confirms its commercial potential through interface testing with a smartphone. The implemented MTM chip is based on a smart card IC, and it includes an interface conversion chip that supports the I/O interface with a mobile device. The chip size is 5mm × 5mm, and the chip does not consume more than 10 mA of current. In addition, it provides additional security functions, including the required functions for an MTM chip. Therefore, with the proposed hardware security chip, it is possible to establish a secure service execution environment for mobile devices.
