ECDSA
Updated: 04/26/2017 by Computer Hope
ECDSA, also known as the Elliptic Curve Digital Signature Algorithm, is a version of the widely-used DSA (Digital Signature Algorithm) algorithm that achieves similar levels of security using a smaller key size. It does this using elliptic curve cryptography, a public key cryptography technique developed in the mid-2000s. Rather than basing its security on a large integer that is the product of multiple large prime factors, it uses an ECDLP (elliptic curve discrete logarithmic problem).
