How E2EE - Signal Protocol secures WhatsApp and Signal chats WhatsApp and Signal use the Signal Protocol with Diffie-Hellman (DH), X3DH, Double Ratchet, Prekeys, and Key Derivation Functions for true end-to-end encryption.

Ever wondered how #WhatsApp and #Signal keep your chats #private?

Both use the #SignalProtocol — a mix of X3DH and Double Ratchet to constantly change #encryption keys.

Even if one message is compromised, the rest stay safe.

$\mathsf{Skye}$: An Expanding PRF based Fast KDF and its Applications A Key Derivation Function (KDF) generates a uniform and highly random key-stream from weakly random key material. KDFs are broadly used in various security protocols such as digital signatures and key...

[2/3] 🚀 **Performance Boost:**
✅ For DH sources, Skye surpasses the state-of-the-art HKDF by 4x-47x.
✅ This results in up to 64% overall speed-up in Signal's key generation phase.
