Elliptic Curve Digital Signature Algorithm
/ˌiː-siː-diː-ɛs-eɪ/
n. “Sign it once, prove it forever.”
ECDSA, or Elliptic Curve Digital Signature Algorithm, is a cryptographic signature scheme built on ECC principles. It allows someone to sign a message, document, or piece of data in a way that anyone else can verify the authenticity using the signer’s public key, while the private key remains secret. Unlike traditional signatures, ECDSA is compact, efficient, and provides strong security even with smaller key sizes.
Elliptic Curve Diffie-Hellman
/ˌiː-siː-diː-eɪtʃ/
n. “Shaking hands securely, without meeting.”
Elliptic Curve Cryptography
/ˌiː-siː-ˈsiː/
n. “Small curves, big security.”
ECC, or Elliptic Curve Cryptography, is a public-key cryptography system that uses the mathematics of elliptic curves over finite fields to create secure keys. Unlike traditional algorithms like RSA, which rely on the difficulty of factoring large integers, ECC relies on the hardness of the elliptic curve discrete logarithm problem. This allows ECC to achieve comparable security with much smaller key sizes, improving performance and reducing computational load.
