Group-Based Attestation: Enhancing Privacy and Management in Remote Attestation.
In: TRUST 2010
[Conference or Workshop Item] , (2010)

Abstract

One of the central aims of Trusted Computing is to provide the ability to attest that a remote platform is in a certain trustworthy state. While in principle this functionality can be achieved by the remote attestation process as standardized by the Trusted Computing Group, privacy and scalability problems make it difficult to realize in practice: In particular, the use of the SHA-1 hash to measure system components requires maintenance of a large set of hashes of presumably trustworthy software; furthermore, during attestation, the full configuration of the platform is revealed. In this paper we show how chameleon hashes allow to mitigate of these two problems. By using a prototypical implementation we furthermore show that the approach is feasible in practice.
