Elliptic Curve Cryptography uses the algebraic structure of elliptic curves over finite fields for asymmetric encryption and digital signatures. ECC achieves the same security strength as RSA with much smaller key sizes (256-bit ECC roughly equals 3072-bit RSA), resulting in faster operations and lower resource usage.
ECC is increasingly preferred over RSA for TLS certificates, mobile devices, and IoT where computational resources are limited. Security architects choose between RSA and ECC based on compatibility and performance requirements. Understanding ECC is important for evaluating post-quantum migration strategies, since ECC is also vulnerable to quantum attacks.
