NET• Cloudflare joins Signal as independent auditor
- Cloudflare joined Signal as an independent auditor for the app’s Key Transparency system supporting automatic key verification.
- Role aims to strengthen trust in end-to-end encryption by verifying a tamper-evident log of key changes for global consistency.
- Auditor pulls batches from the log, cryptographically checks consistency, then signs updates for Signal to distribute to users.
- Cloudflare said its auditor operates only on cryptographic proofs, without access to user identifiers, public keys, or message content.
- Move extends Cloudflare’s key-transparency work in messaging, following its 2024 appointment as a WhatsApp auditor.
