WebThe difficulty of solving the ECDLP is the foundation of the security of elliptic curve cryptography (ECC). A connection between the lifting problem on a curve in Weierstrass form and the ECDLP has been stressed by Silverman. Based on this, in order to study the ECDLP, we compute the exponential map for Edwards curves, which are more efficient … WebAbstract —Since Edwards curves were introduced to elliptic curve cryptography by Bernstein and Lange in 2007, they have receiv ed a lot of attention due to their very fast group law operation.

In mathematics, the Edwards curves are a family of elliptic curves studied by Harold Edwards in 2007. The concept of elliptic curves over finite fields is widely used in elliptic curve cryptography. Applications of Edwards curves to cryptography were developed by Daniel J. Bernstein and Tanja Lange: they … See more The equation of an Edwards curve over a field K which does not have characteristic 2 is: $${\displaystyle x^{2}+y^{2}=1+dx^{2}y^{2}\,}$$ for some See more In the context of cryptography, homogeneous coordinates are used to prevent field inversions that appear in the affine formula. To avoid inversions in the original Edwards … See more Tripling can be done by first doubling the point and then adding the result to itself. By applying the curve equation as in doubling, we obtain See more There is another coordinates system with which an Edwards curve can be represented; these new coordinates are called extended … See more (See also Weierstrass curve group law) Every Edwards curve $${\displaystyle x^{2}+y^{2}=1+dx^{2}y^{2}}$$ over field K with characteristic not equal to 2 with $${\displaystyle d\neq 1}$$ is birationally equivalent to an elliptic curve over the same field: See more Mixed addition is the case when Z2 is known to be 1. In such a case A=Z1 Z2 can be eliminated and the total cost reduces to … See more Bernstein and Lange introduced an even faster coordinate system for elliptic curves called the Inverted Edward coordinates in which the coordinates (X : Y : Z) satisfy the curve (X + Y )Z … See more In public-key cryptography, Edwards-curve Digital Signature Algorithm (EdDSA) is a digital signature scheme using a variant of Schnorr signature based on twisted Edwards curves. It is designed to be faster than existing digital signature schemes without sacrificing security. It was developed by a team including Daniel J. Bernstein, Niels Duif, Tanja Lange, Peter Schwabe, and Bo-Yin Yang. The reference implementation is public-domain software.
