Struct ntru::types::NtruProdPoly
[−]
[src]
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
[src]
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
