Square Root Function for the SEAL Ciphertexts

211 views Asked by At

Is there a way to calculate the square root function on Ciphertexts? I didn't see it see it in the evaluator method. If it's not possible with SEAL 2.3.1 will it be possible with future SEAL releases?

This functionality is not in SEAL at the moment. SEAL is a low level library and aims to provide only the most fundamental building blocks; including a high-level function such as sqrt in SEAL is unreasonable since how exactly it is best evaluated (on encrypted data) depends a lot on the context. Therefore, sqrt is unlikely to ever be provided by the SEAL API.
