virtual void ModReduceInternalInPlace(Ciphertext<DCRTPoly> &ciphertext, size_t levels) const override

Method for scaling in-place.

cipherText will have modulus reduction performed in-place.

Parameters

• cipherText – is the ciphertext to perform modreduce on.

• levels – the number of towers to drop.

virtual void LevelReduceInternalInPlace(Ciphertext<DCRTPoly> &ciphertext, size_t levels) const override

Method for in-place Level Reduction in the CKKS scheme. It just drops “levels” number of the towers of the ciphertext without changing the underlying plaintext.

Parameters

• cipherText1 – is the ciphertext to be level reduced in-place

• levels – the number of towers to drop.
