Im not a cryptography expert but from what i've learnt about homomorphic encryption in my courses its nowhere close to being usable at reasonable speeds

- Joker_vD 6y agoYeah, turning 1 bit of plaintext into 20 MB of ciphertext kills any hope for "reasonable speed". I have a toy functional language implementation that has no built-in data structures whatsoever, and even it in the end represents a bit only as an 8-byte closure.
- ssmiler 6y agoMaybe in batched HE schemes. In https://github.com/tfhe/tfhe https://github.com/tfhe/tfhe the ratio is much smaller, 2.5kB per plaintext bit.
