WebWhat is elliptical curve cryptography (ECC)? Elliptical curve cryptography (ECC) is a public key encryption technique based on elliptic curve theory that can be used to create faster, smaller and more efficient cryptographic keys. WebSep 20, 2024 · Elliptic Curve Cryptography(ECC) is based on the algebraic structure of elliptic curves over finite fields. The use of elliptic curves in cryptography was independently suggested by Neal Koblitz and Victor Miller in 1985. From a high level, Crypto++ offers a numbers of schemes and alogrithms which operate over elliptic curves.

Its security is based on the difficulty to solve discrete logarithms on the field defined by specific equations computed over a curve. ECC can be used to create digital signatures or to perform a key exchange.

For example, secp160r1 uses a 160-bit prime field. X and Y can be up to 160 bits long. So (X,Y) is 320 bits. The (X,Y) point can be represented in compressed form where only the X value and a bit of information is given, since Y is a function of X.
