Introducing Zero-Knowledge Proofs for Private Web Attestation with Cross/Multi-Vendor Hardware

This post introduces the development and open-sourcing of a Zero-Knowledge Proof system for private web attestation. This innovation aims to enhance user privacy by allowing websites to verify the authenticity of hardware security keys without learning sensitive information like the manufacturer or model, thereby reducing the risk of user identification and moving beyond the limitations of existing WebAuthn attestation. It represents a significant step in Cloudflare's ongoing efforts to improve privacy across the internet.
