Elliptic Curve Cryptography (ECC)
Also known as: ECC, Elliptic Curve Crypto, Asymmetric Curve Cryptography
A type of public-key cryptography based on the algebraic structure of elliptic curves over finite fields.

Elliptic Curve Cryptography (ECC) is a form of asymmetric cryptography used extensively in blockchain systems to generate public-private key pairs. ECC provides strong security with shorter key lengths compared to traditional methods like RSA, making it efficient for mobile and embedded devices. In cryptocurrencies, ECC is used for transaction signing and address generation. Bitcoin, for example, uses the secp256k1 curve. ECC's security relies on the difficulty of solving the Elliptic Curve Discrete Logarithm Problem (ECDLP), making it resistant to brute-force and quantum attacks (to some extent).
