Abstract
At present, GLV/GLS scalar multiplication mainly focuses on finding and constructing more and more efficient computable endomorphisms. We research on the applications of GLV/GLS algorithms on twisted Edwards curves. Firstly, we present the concrete construction of efficiently computable endomorphism for this type of curves over prime field by exploiting birational equivalence between curves, and obtain 2-dimensional GLV method. Using birational equivalence and Frobenius mapping between curves, we present methods to construct efficiently computable endomorphisms of this type of curves and obtain 2-dimensional GLS method. Finally, we obtain the 4-dimensional GLV algorithm by using higher degree twists. The experimental conclusion demanstrates that the speedups of 2-dimensional and 4-dimensional GLV methods than 5-NAF method exceed 37.4% and 104.9% for twisted Edwards curves respectively.
