Equidistribution Among Cosets of Elliptic Curve Points in Intervals
Journal of Mathematical Cryptology, 2020 In a recent paper devoted to fault analysis of elliptic curve-based signature schemes, Takahashi et al. (TCHES 2018) described several attacks, one of which assumed an equidistribution property that can be informally stated as follows: given an elliptic ...

On Pythagorean Triples and the Primitive Roots Modulo a Prime
Journal of Mathematics, 2021 In this paper, we use the elementary methods and the estimates for character sums to study a problem related to primitive roots and the Pythagorean triples and prove the following result: let p be an odd prime large enough.
