Hello! I want to make sure I understand this parameter setting correct:
If I want to work with a ring dimension smaller than 16.384, I need to set HEStd_NotSet = <SecurityLevel.HEStd_NotSet>. My question is does this parameter affect in any way the homorphic encryption- i.e makes the cipher text to not be calculated correctly or it just makes the polynomial coefficients be smaller and consequently be more susceptible to attacks .
Thank you!
That setting only affects the security level of the instantiated scheme. It allows the user to set the crypto parameters freely, like choosing a small ring dimension.
Functionality should not be affected. The ciphertext will look normal and can be used in homomorphic computation as if it were generated under a secure setting.
