About Elliptic Curve Cryptography

Elliptic Curve Cryptography (ECC) is an approach to public-key cryptography based on the algebraic structure of elliptic curves over finite fields. ECC requires smaller keys compared to non-EC cryptography to provide equivalent security.

  • ECC uses elliptic curves over finite fields to create cryptographic keys.
  • It offers the same level of security as RSA but with much smaller key sizes.
  • A 256-bit ECC key provides comparable security to a 3072-bit RSA key.
  • ECC is widely used in mobile devices and IoT applications due to its efficiency.
Key Advantages of ECC:
  • Smaller Key Size: ECC keys are much smaller than RSA keys for the same security level.
  • Faster Computation: ECC operations are generally faster than equivalent RSA operations.
  • Lower Resource Usage: ECC requires less memory and CPU power, making it ideal for constrained devices.
  • Future-Proof: As key sizes need to increase for security, ECC scales better than RSA.
Common ECC Curves:
  • NIST P-256 (secp256r1): A 256-bit prime field curve standardized by NIST.
  • NIST P-384 (secp384r1): A 384-bit prime field curve offering higher security.
  • NIST P-521 (secp521r1): A 521-bit prime field curve for maximum security.
  • secp256k1: The curve used by Bitcoin and many other cryptocurrencies.
