Similarly, if something were uniform, either statistically or computationally, modulo R∨ , then m times it will be uniform modulo mR∨ and thus uniform modulo R, since mR∨ is an additive subgroup of R. This transformation is not completely tight (except in the case that Φm (X) = X m/2 + 1) because we end up with something that is uniform modulo a subgroup of R, whereas we only use the randomness modulo R. This loss of tightness, however, is very small, resulting in the noise being at most m/φ(m) “larger than necessary” (see the discussion after Theorem 2).

Furthermore, if deg gi = di ≤ b for all gi and the underlying monomial ordering is compatible with deg, we have the following alternative sampling algorithm, which gives the same distribution: Let ti ←$ P≤b−di uniformly for i ∈ {1, . . , m} and sample f ∈ I as f = m i=1 ti · gi . Proof. Clearly, both ways of sampling give us polynomials from I≤b . We observe that both f → f mod G and (t1 , . . tm ) → f = m i=1 ti · gi are Fq -linear maps. Since surjective linear maps preserve uniform distributions, both resulting distributions are uniform on their respective supports.

7 By the properties of a monomial order, LT(t · h) = t · H. Since t·H ∈ Q, this is not reduced modulo G, so we have LT((t·h) mod G) = t·H. Since A(t · h) = 0, we have t · h ∈ I≤b ⊕ Q≤k . This implies (t · h) mod G ∈ Q≤k , in particular (t · h) mod G has degree at most k. It follows that H has degree at most k − deg t = k − α − 1. This ﬁnally proves the theorem. Remark 3. Algorithm 5 was optimized for simplicity of analysis. We can get a better running time by using the highly structured nature of the equations on 7 Note that if k < d, any t of degree α + 1 will do without the restriction on n.
