ELLIPTIC CURVES

Abstract

Using Elliptic curves as asubstitute to RSA for signcryption , technique which accomplishes digital signature and encryption in single procedure.

Key takeaways

  • Thus the set of the multiples of P is a cyclic subgroup of the group formed by the elliptic curve.
  • ➢ The order of P is linked to the order of the elliptic curve by Lagrange's theorem which states that the order of a subgroup is a divisor of the order of the parent group.
  • Let P and Q be two known points on an elliptic curve over a finite field .
  • Note that both Alice and Bob are using the same domain parameters: the same base point G on the same elliptic curve on the same finite field.
  • In the initialization phase, system generates and publishes domain parameters of elliptic curve, and each user generates his own private key and the related public key.
