What is an embedding degree?
In the context of Algebraic Geometry and Cryptography, the embedding degree is a value associated with an algebraic curve, more precisely with a cyclic subgroup of the abelian group associated with the curve.Given an elliptic curve (or an hyperelliptic curve), we can consider its associated abelian group - in the case of an elliptic curve corresponds to the set of points - and a cyclic subgroup G, typically its largest.Using pairings (more notably, the Tate pairing or Weil pairing), we can map G to a subgroup of a finite field.More precisely, if the curve was defined over a finite field of size q, G is mapped to a subgroup of a finite field of size qk for some integer k. The smallest such integer k is called the embedding degree.Moreover, if G has size n it satisfies n | qk - 1 (n divides qk - 1).In Cryptography, the embedding degree most notably appears in security constraints for Elliptic Curve Cryptography and in the more recent area of Pairing Based Cryptography. Pairings allow us to "map" problems over elliptic curves to problems over finite fields and vice-versa with the security and efficiency issues of each side.For example, given the known attacks for the Discrete Logarithm Problem over elliptic curves and over finite fields, in Elliptic Curve Cryptography curves with a very small embedding degree (lower than 6, say) are usually avoided. On the other hand, because in Pairing Based Cryptography operations are often done on both groups, curves with too high embedding degrees are avoided.
Is there a simple test for determining whether an elliptic curve has an infinite number of rational solutions?
Equations of the form y2 = x3 + ax + b are powerful mathematical tools. The Birch and Swinnerton-Dyer conjecture tells how to determine how many solutions they have in the realm of rational numbers-information that could solve a host of problems, if the conjecture is true.
How the sine curve related to a curve?
Basically, it IS a curve.
What is the name of 3 types of non-Euclidean geometries?
Hyperbolic, elliptic, projective are three possible answers.
Bell-shaped curve used to illustrate data signifies a curve?
It's true: a curve is a curve. Did you really need me to tell you that?
What is the formula structure for EDDHSA?
EDDSA (Elliptic Curve Digital Signature Algorithm) is a digital signature algorithm based on elliptic curve cryptography. It uses a specific elliptic curve equation (y^2 = x^3 + ax + b) to generate key pairs and perform digital signature operations. The security of EDDSA relies on the difficulty of solving the elliptic curve discrete logarithm problem.
What is the Eliptic?
The elliptic curve is a type of mathematical curve defined by an equation of the form y^2 = x^3 + ax + b, where a and b are constants. Elliptic curves have applications in cryptography, number theory, and other areas of mathematics. They play a fundamental role in elliptic curve cryptography, a widely used method for secure communication.
A java code for Elliptic Curve Cryptography?

When did Riemann create elliptic geometry?
Riemann created elliptic geometry in 1854.
Is the word achoo alliterative onomatopoeic lyrical or elliptic?
The word "achoo" is an onomatopoeic word, representing the sound of a sneeze. It is not alliterative, lyrical, or elliptic.
