Short paper: Lightweight remote attestation using physical functions
Abstract
Remote attestation is a mechanism to securely and verifiably obtain information about the state of a remote computing platform. However, resource-constrained embedded devices cannot afford the required trusted hardware components, while software attestation is generally vulnerable to network and collusion attacks. In this paper, we present a lightweight remote attestation scheme that links software attestation to remotely identifiable hardware by means of Physically Unclonable Functions (PUFs). In contrast to existing software attestation schemes, our solution (1) resists collusion attacks, (2) allows the attestation of remote platforms, and (3) enables the detection of hardware attacks due to the tamper-evidence of PUFs.
