Improving the scalability of platform attestation
Frederic Stumpf, Andreas Fuchs, Stefan Katzenbeisser, Claudia Margot Eckert · 2008
In the process of platform attestation, a Trusted Platform Module is a performance bottleneck, which causes enormous delays if multiple simultaneously attestation requests arrive in a short period of time. In this paper we show how the scalability of platform attestation can be improved. In this context, we propose three protocols that enable fast and secure integrity reporting for servers that have to handle many attestation requests. We implemented all of our protocols and compared them in terms of security and performance. Our proposed protocols enable a highly frequented entity to timely answer incoming attestation requests.
