Function masked_multiply_public 

pub fn masked_multiply_public(
    masked: &MaskedPoly,
    public: &[i16; 256],
    out: &mut MaskedPoly,
)

Multiply a masked polynomial by a public polynomial in NTT domain.

Computes (s0 + s1) * p = s0*p + s1*p by multiplying each share independently. This is secure because p is public data – there is no secret-times-secret interaction that would require second-order masking.

Arguments

• masked - The masked secret polynomial (NTT domain).
• public - A public polynomial (NTT domain).
• out - Output masked polynomial for the product.
