Definition of elliptic curve: & nbsp; & nbsp; & nbsp; an elliptic curve is a curve which satisfies the equation in the projective plane & nbsp; & nbsp; & nbsp; y2z + a1xyz + a3yz2 = X3 + a2x2z + a4xz2 + a6z3. & nbsp; a process of encrypted communication using elliptic curve: 1. User a selects an elliptic curve EP (a, b), and takes a point on the elliptic curve as the base point G. 2. User a selects a private key K and generates a public key K = kg. 3. User a transmits EP (a, b) and points K, G to user B. 4. After receiving the message, user B encodes the plaintext to be transmitted to a point m on EP (a, b)
