Universal Remote Attestation for Cloud and Edge Platforms
Simon Ott, Monika Kamhuber, Joana Pecholt, Sascha Wessel · 2023
With more computing workloads being shifted to the cloud, verifying the integrity of remote software stacks through remote attestation becomes an increasingly important topic. During remote attestation, a prover provides attestation evidence to a verifier, backed by a hardware trust anchor. While generating this information, which is essentially a list of hashes, is easy, examining the trustworthiness of the overall platform based on the provided list of hashes without context is difficult. Furthermore, as different trust anchors use different formats, interaction between devices using different attestation technologies is a complex problem.
