LWE Parameter selection
For the LWE parameter selection we could use the LWE estimator: https://github.com/malb/lattice-estimator Another approach would be to use approximated formulas: https://eprint.iacr.org/2024/1001
Ooh and they have a github repo with the formulas implemented in python: https://github.com/sergirovira/fastparameterselection/
If we are talking about selecting N and Q, the above tools suffices. Another alternative is Homomorphic Encryption Standard which recommended a set of LWE parameters for different security levels, implementation could look up that table as long as Q does not exceed Qmax for a specific N.
OpenFHE select N/Q in this way.
Yet there are still more steps to select other parameters like qi.
Looks also like there is just published a follow up work: https://eprint.iacr.org/2024/1895.pdf
