Elliptic-curve Diffie–Hellman
Okay kiddo, so you know how sometimes we need to keep things a secret and not share them with other people? Well, sometimes when we want to share something with someone else but we don't want anyone else to see it, we can use something called encryption.
Elliptic-curve Diffie-Hellman (ECDH) is a way of doing encryption that uses math to help two people agree on a secret code that no one else knows. It's kind of like having a special language that only the two people who know it can understand.
The math part of ECDH uses something called an elliptic curve. Think of an elliptic curve like a weird-shaped slide at a playground. When we use ECDH, we choose two points on the curve (like starting at the top of the slide and ending at the bottom) and use some special math to figure out a secret code that only the two people who know the points can understand.
This secret code is used to encrypt a message so that only the person who knows the secret code can read it. It's like having a secret password that only the two people who know it can use to unlock a secret message.
ECDH is important because it helps make sure that only the two people who are supposed to be sharing information can see it. It keeps other people from spying on what they're saying or doing. And that's why it's an important part of keeping information safe and secure.
