Reconfigurable trusted computing in hardware

Trusted Computing (TC) is an emerging technology towards building trustworthy computing platforms. The Trusted Computing Group (TCG) has proposed several specifications to implement TC functionalities by extensions to common computing platforms, particularly the underlying hardware with a Trusted Platform Module (TPM). However, actual TPMs are mostly available for workstations and servers nowadays and rather for specific domain applications and not primarily for embedded systems. Further, the TPM specifications are becoming monolithic and more complex while the applications demand a scalable and flexible usage of TPM functionalities. In this paper we propose a reconfigurable (hardware) architecture with TC functionalities where we focus on TPMs as proposed by the TCG specifically designed for embedded platforms. Our approach allows for (i) an efficient and scalable design and update of TPM functionalities, in particular for hardware-based crypto engines and accelerators, (ii) establis...
