Confidential Computing and Related Technologies: A Review

Publikation: Vorabdruck/Dokumentation/BerichtVorabdruck (Preprint)



With a broad spectrum of technologies for the protection of personal data, it is important to be able to reliably compare these technologies to choose the most suitable one for a given problem. Although technologies like Homomorphic Encryption have matured over decades, Confidential Computing is still in its infancy with not only informal but also incomplete and even conflicting definitions by the Confidential Computing Consortium (CCC). In this work, we present key issues in definitions and comparison among existing technologies by CCC. We also provide recommendations to achieve clarity and precision in the definitions as well as fair and scientific comparison among existing technologies. We emphasize on the need of formal definitions of the terms and pose it as an open challenge to the community.
