The Key Exchange:

The Key Exchange: NoiseIK ▪ One peer is the initiator; the other is the responder. ▪ Each peer has their static identity – their long term static keypair. ▪ For each new handshake, each peer generates an ephemeral keypair. ▪ The security properties we want are achieved by computing ECDH() on the combinations of two ephemeral keypairs and two static keypairs. ▪ Session keys = Noise( ) ECDH(ephemeral, static), ECDH(static, ephemeral), ECDH(ephemeral, ephemeral), ECDH(static, static) ▪ The first three ECDH() make up the “triple DH”, and the last one allows for authentication in the first message, for 1-RTT.

The Key Exchange ▪ Very limited set of primitives: ▪ Elliptical curve Diffie-Hellman, hashing, authenticatedencryption. ▪ Just 1-RTT. ▪ Extremely simple to implement in practice, and doesn’t lead to the type of complicated messes we see in OpenSSL and StrongSwan. ▪ No certificates, X.509, or ASN.1: both sides exchange very short (32 bytes) base64-encoded public keys, just as with SSH.
