Constructing Multidimensional Differential Addition Chains and their Applications
differential addition chains side channel resistance elliptic curves
2017/4/12
We propose new algorithms for constructing multidimensional differential addition chains and for performing multidimensional scalar point multiplication based on these chains. Our algorithms work in a...
Differential Addition on Edwards Curves

We give two parametrizations of points on Edwards curves
that omit the X coordinate. The first parametrization leads to a differential
addition formula that has the cost 5M+ 4S, a doubling formula
