WebDec 26, 2024 · Issue 1: In BGV and BFV, you have to keep track of what is called the plaintext modulus p. Simply, imagine you have p =9 and that you do enc(4) + enc(8) = enc(3) (mod 9). Webwhich avoids bootstrapping. If one wants to use the bootstrapped version then the best method requires to evaluate 7nMux gates, where each gate takes around 26 millisecond to be evaluated, which makes a total of 182nmillisecond. Schemes from the second category (BGV and BFV) can use SIMD techniques

WebJan 4, 2024 · Bootstrapping using the BGV or BFV schemes requires assuming that lattice problems are computationally hard to approximate within factors that grow superpolynomially in the lattice dimension n. This is a stronger assumption than the inapproximability within polynomial factors required by standard (non-homomorphic) … WebMar 2, 2024 · The BFV scheme is good for representing lots of integers inside a polynomial and we can even operate on them individually relatively fast. However, bootstrapping on BFV is infeasible, such that no library even implements it.
