ECC
Definition
ECC, or Elliptic Curve Cryptography, is a public key cryptography approach that provides strong security using smaller key sizes than many older asymmetric algorithms.
Examples
- A mobile app uses ECC-based key exchange to help create a secure encrypted session without heavy processing overhead.
- A digital certificate uses an elliptic curve algorithm for public key operations instead of RSA.

Modern encryption must do two things well. It must be strong enough to resist attack, and it must work efficiently on real devices. That second point matters more than many beginners realize. Security is not useful if it is so heavy that it slows systems down too much or drains battery life on small devices. ECC became important because it helps solve that balance.
Elliptic Curve Cryptography provides strong public key security with smaller keys than many older approaches. That does not mean it is simple, but it does mean it is often practical. In environments where speed, storage, and power matter, ECC can be a very attractive choice.
