Define elliptic curve cryptography

WebThe reason elliptic curves are used in cryptography is the strong one-way function they enable. Any two points on an elliptic curve can be “dotted” (“multiplied”) together to get a new point on the curve. ... It is known that if P=(x,y) is on the elliptic curve E, it is possible to define a “product” or “scalar multiplication ... WebThe DDH assumption does not hold on elliptic curves over () with small embedding degree (say, less than ⁡ ()), a class which includes supersingular elliptic curves. This is because the Weil pairing or Tate pairing can be used to solve the problem directly as follows: given P , a P , b P , c P {\displaystyle P,aP,bP,cP} on such a curve, one ...
