Remote attestation is an important security mechanism designed to detect software attacks, typically
realized as a challenge‐response protocol. It allows a trusted verifier to capture the state of a piece of
software, before execution, of a (potentially untrusted or malware‐infected) remote device ‐ a prover.
Static attestation only provides assurance of the integrity of the piece of software (the binaries) but does
not verify its execution. More recently, several attestation schemes are proposed to also capture the
dynamic state of a remote device to enable detection of a wide range of runtime attacks. However, all
schemes in literature mainly focus on the different mechanisms at the prover’s side. In their attempts to
reduce the workload on the prover (often a low‐end embedded device), many assumptions are made with
regards to the capabilities of the verifier. In this thesis/HiWi, we aim to investigate and evaluate the
verifier’s end of these schemes to evaluate remote attestation protocols comprehensively.

Analyzing the state‐of‐art remote attestation schemes in order to validate their assumptions.
Implementation of the different verifier models for different schemes.
Evaluation and comparison of the different verifier models.
