### Understanding FHE bootstrapping: value of $q$ fed to lattice estimator

I am implementing OpenFHE. In the implementation I'm generating the modulus chain as shown in the example here. I am trying to run Lattice estimator for the same parameters in this example. I wanted ...

### Urgent help with R-LWE Parameters Choice

I am trying to understand CKKS bootstrap algorithm and wanted to understand how is p (plaintext modulo) and q (ciphertext modulo) related in determining the size of the modulus chain. Suppose my ring ...

### Definition of Dual Lattice: $\vec{v}\in span_{\mathbb{R}}(\mathcal{L}(\mathbf{B}))$

Consider the definition of the dual lattice for a lattice $\mathcal{L}(\mathbf{B}_{m\times n})\in\mathbb{R}^{m}$ where $\mathbf{B}\in\mathbb{R}^{m\times n}$ and $n\leq m$ [sp2 Seminar, Luxembourg 2019,...

### Definition of Dual Lattice

1- Can someone explain why we have the definition of dual of a lattice like $\Lambda^*=\{\vec{v}\in span(\textbf{B}): \langle \vec{v},\vec{x} \rangle \in \mathbb{Z}, \forall \vec{x} \in \Lambda\}$. 2-...
