Elliptic Curve Digital Signature Algorithm (ECDSA)
This post is dedicated to the memory of Dr. Scott Vanstone, inventor of the ECDSA algorithm.
The “Elliptic Curve Digital Signature Algorithm (ECDSA)” is a variant of the ElGamal signature scheme and is considered the elliptic curve equivalent of the “Digital Signature Algorithm (DSA)”.
Elliptic Curve
Consider that Alice has to sign a message M, that needs to be verified by Bob.
The ECDSA has the following steps:
Initialisation
Key-pair generation
Signing
Verification
