Design and implementation of mobile trusted module for trusted mobile computing

This paper presents the design and implementation of a Mobile Trusted Module (MTM) which should satisfy small area and low-power condition. Unlike the general Trusted Platform Module (TPM) for PCs, the MTM, that is to be employed in mobile devices, has very stringent limitations with respect to available power, circuit area and so on. Therefore, a MTM needs the spatially-optimized architecture and design method. We introduce the requirements for a MTM design and then implement a compact and power efficient MTM chip based-on the introduced requirements. The designed MTM can support all the necessary functions for trusted mobile platforms. The MTM chip covers 400 K logic gates and consumes at most 10 mA.
