Pairing-based cryptography
Hey there kiddo, do you remember how we use secret codes to keep our messages private? Paired-based cryptography is another way of doing just that, but it involves some pretty complicated maths!
So, in normal, everyday secret codes, we use a key to encrypt a message, making it unreadable to anyone who doesn't know the key. But in pairing-based cryptography, instead of using a single key, we use two keys that are linked together.
Let’s imagine that we have two lockers next to each other. The keys that open each locker are not the same, but they have a special relationship between them. When you put the two keys together, they unlock a third secret locker that nobody knows about.
That’s kind of what happens with pairing-based cryptography. You have two keys that work together to unlock a secret code that nobody else can access. These two keys are called public and private keys.
The public key is made available to everyone and is used to encrypt messages. You can think of this key as a lock. When someone wants to send you an encrypted message, they use your public key to lock it.
The private key, on the other hand, is like the key that unlocks the lock. Only the person who owns the private key can use it to decrypt the message that was locked with the corresponding public key.
This is a very good way to keep our messages completely private even if somebody else gets their hands on our public key because without the private one, they can't break the code.
Pairing-based cryptography is a really powerful tool that is used for all sorts of things like secure communication, digital signatures, and even online shopping. So you see kiddo, by keeping our secrets safe, we can do a lot of amazing things!
