Webso we have found a base for our dual lattice: B ∨ = ( B − 1 ) T ∈ G L n ( R ) B^\vee = (B^{-1})^T \in GL_n(\mathbb{R}) B ∨ = ( B − 1 ) T ∈ G L n ( R ) n = 5 # lattice dimension WebJan 8, 2024 · Now, the following vector will be inside the lattice generated by this basis: because it’s the sum of: 1 times the first row times the second row times the third row etc. This vector is pretty small! The entries only have 128 bits, compared to what we started with which was 134 bits. tsb bank stafford branch

Our ciphertext is e ≡ rh + m (mod q). Make a new row vector (0 N, e) by prepending N 0’s to the coefficients of e. This is in the same dimensional space as our lattice, but it’s not necessarily a lattice point. However, we can also write it as. (0 N, e) = (0 N, rh + m (mod q)) = (r, rh (mod q)) + (-r, m). tsb bank switch bonus
