The key server can perform a first elliptic curve Diffie-Hellman (ECDH) key exchange using the device public key and a network private key to derive a secret X1. The key server can send the secret X1 to the server. The server can derive an ECC PKI key pair and send to the device the server public key. The server can conduct a second ECDH key exchange using the derived server secret key and the device public key to derive a secret X2. The server can perform an ECC point addition using the secret X1 and secret X2 to derive a secret X3. The device can derive the secret X3 using (i) the server public key, a network public key, and the device private key and (ii) a third ECDH key exchange."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"ECDHE key exchange for server authentication and a key server","description":"A server can receive a device public key and forward the device public key to a key server.
