A Mobile Trusted Platform Module (mTPM) Architecture

We present the architecture of a mobile Trusted Platform Module (mTPM). Current implementations of TPM architectures assume physical bindings between the TPM and a single hardware platform. In this paper we introduce an alternative where a TPM is bound to a single virtual machine (VM) on a portable device, following the specifications provided by the Trusted Computing Group (TCG). By communicating with the VM infrastructure on the host machine, an mTPM offers various security functions similar as a physical TPM does. The mTPM is a mobile solution that will be beneficial to any professional who requires a portable, secure computing environment.
