WebDealing with this noise has led to two different approaches in FHE. The first approach, called “leveled” (e.g. BGV and CKKS) tries to do just enough computation to avoid noise overflowing the data; the second approach called “bootstrapped” (e.g. TFHE) applies a special operation called bootstrapping to reduce noise as needed.
