Is there support for BFV bootstrapping in openFHE? I recollect there was support in Palisade.
Also how is leveled BFV different in implementation from leveled BGV scheme?
No, there is no current support for BGV or BFV bootstrapping in OpenFHE. The reason is that the performance is much poorer than for CKKS or FHEW. There is active research into improving the performance of BGV/BFV bootstrapping that looks promising; so in the future we might include it.
To understand how leveled BFV and BGV schemes relate, please read https://eprint.iacr.org/2021/204.pdf.
Thank you. I see the leveled support is present for both but through different operations. This helps. Thanks.
