Algorithm 1 Elliptic curve Diffie-Hellman (ECDH) key agreement.
1:	Agree upon domain parameters (p, a, b, G, n, h)
2:	Alice:
3:	Private key: dA ⇐ A random integer in range: [1, n − 1]
4:	Public key: QA ⇐ dAG
5:	Alice's key pair will be (dA, QA)
6:	Send QA to Bob
7:	Bob:
8:	Private key: dB ⇐ A random integer in range: [1, n − 1]
9:	Public key: QB ⇐ dBG
10:	Bob's key pair will be (dB, QB)
11:	Compute (xk, yk) ⇐ dBQA, where xk is the shared key
12:	Send QB to Alice
13:	Alice:
14:	Compute (xk, yk) ⇐ dAQB, where xk is the shared key
