This probability is used in the analysis of symmetric-key primitives that combine XOR and modular addition, such as the increas-ingly popular Addition-Rotation-XOR (ARX) constructions.

We provide the missing proof for Theorem 3 of the FSE 2004 paper, which states that maxα,β adp⊕ (α, β → γ) = adp⊕ (0, γ → γ) for all γ. Furthermore, we prove that there always exist either two or eight distinct pairs α, β such that adp⊕ (α, β → γ) = adp⊕ (0, γ → γ), and we obtain recurrence formulas for calculating adp⊕ .
