WebElliptic curve cryptography makes use of elliptic curves in which the variables and coefficients are all restricted to elements of a finite field. Two families of elliptic curves are used in cryptographic applications: prime curves over Zp and binary curves over GF (2m). For a prime curve over Zp, we use a cubic equation in which the WebThe ElGamal signature scheme is a digital signature scheme which is based on the difficulty of computing discrete logarithms.
