Sustainable Trusted Computing: A Novel Approach for a Flexible and Secure Update of Cryptographic Engines on a Trusted Platform Module
Trusted computing is gaining an increasing acceptance in the
industry and finding its way to cloud computing.
With this penetration, the question arises whether the concept of hardwired security modules will cope with the increasing sophistication and security requirements of future IT systems and the
ever expanding threats and violations.
So far, embedding cryptographic hardware engines into the Trusted Platform Module (TPM) has been regarded as a security feature. However, new developments in cryptanalysis, side-channel analysis, and the emergence of novel powerful computing systems, such as quantum
computers, can render this approach useless.
Given that, the question arises: Do we have to throw away all TPMs and
lose the data protected by them, if someday a cryptographic
engine on the TPM becomes insecure?
To address this question, we present a novel architecture called Sustainable Trusted Platform Module (STPM), which guarantees a secure update of the TPM cryptographic engines without compromising the system’s trustworthiness.
The STPM architecture has been implemented as a proof-of-concept on top of a Xilinx Virtex-5 FPGA platform, demonstrating the test cases with an update of the fundamental hash and asymmetric engines of the TPM
