A first intermediate modular reduction result is calculated. A value corresponding to four times the first number is added to the first intermediate modular reduction result, generating a second intermediate modular reduction result. A value corresponding to the first number multiplied by a most significant word of the second intermediate modular reduction result plus 1, is subtracted from the second intermediate modular reduction result, generating a third intermediate modular reduction result. A cryptographic operation is performed using a result of the modular reduction calculation."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Protection of a modular reduction calculation","description":"A modular reduction calculation on a first number and a second number is protected from side-channel attacks, such as timing attacks.
