Computing projective equivalences of planar curves birationally equivalent to elliptic and hyperelliptic curves▪ We present algorithms to find the projective equivalences between two planar curves, birationally equivalent to either elliptic or hyperelliptic curves. The main idea, in both cases, is to find first a corresponding birational mapping...
Projective Equivalences Between Planar Curves Birationally Equivalent to Elliptic or Hyperelliptic Curves
The study of projective equivalences in planar curves that are birationally equivalent to elliptic or hyperelliptic curves is a significant area in cryptography. Our focus is on presenting algorithms that efficiently identify these equivalences. By first determining a birational mapping, we can effectively evaluate these relationships, which has promising implications for secure communications.
Four-Dimensional GLV via the Weil Restriction
The well-known Gallant-Lambert-Vanstone (GLV) algorithm innovatively employs computable endomorphisms to expedite the scalar multiplication of points on an abelian variety. Freeman and Satoh have introduced cryptographic applications for two families of genus 2 curves that leverage this principle. These advancements highlight the increasing efficiency in encrypting and decrypting data, which is vital for modern secure communication systems.
A Note on the Ate Pairing
The Ate pairing has garnered attention for its computational efficiency on ordinary elliptic curves, particularly those with low Frobenius trace values. However, not all elliptic curves suited for pairing have these characteristics. This research extends the efficient computation methods of Ate pairing to a broader range of pairing-friendly elliptic curves, thereby enhancing their applicability and security.
