Struct ntru::types::NtruProdPoly

pub struct NtruProdPoly {
    // some fields omitted
}

A product-form polynomial, i.e. a polynomial of the form f1*f2+f3 where f1,f2,f3 are very sparsely populated ternary polynomials.

Methods

impl NtruProdPoly

fn new(n: u16, f1: NtruTernPoly, f2: NtruTernPoly, f3: NtruTernPoly) -> NtruProdPoly

fn rand(n: u16, df1: u16, df2: u16, df3_ones: u16, df3_neg_ones: u16, rand_ctx: &NtruRandContext) -> Option<NtruProdPoly>

Random product-form polynomial

Generates a random product-form polynomial consisting of 3 random ternary polynomials. Parameters:

• N: the number of coefficients, must be NTRU_MAX_DEGREE or less
• df1: number of ones and negative ones in the first ternary polynomial
• df2: number of ones and negative ones in the second ternary polynomial
• df3_ones: number of ones ones in the third ternary polynomial
• df3_neg_ones: number of negative ones in the third ternary polynomial
• rand_ctx: a random number generator
