What are security protocols?

Security protocols are like secret handshakes that help friends keep their messages safe from sneaky eavesdroppers.

Imagine you and your best friend want to send each other notes during class, but the teacher is watching. You both agree on a special way to write your notes, maybe you use only bold words or draw little stars at the end of every message. This special way is like a security protocol, it helps you send messages without anyone else understanding them.

How It Works

Think of the internet as a big playground where everyone can see everything. A security protocol is like putting up a fence and a lock around your messages so only the person you're talking to can read them. They might even use a secret code or a special key to open it.

Why It Matters

Without these secret handshakes, sneaky people could read all your messages, just like how someone might sneak up behind you in the playground and hear everything you say. But with security protocols, only your friend can understand what you're saying, and that’s pretty cool!
