The security level

Hi, I saw a parameter (n_bits=3) when defining a model. Does it mean the security level? Or when I use it to encrypt inference, does it satisfy 128-bits security?

Hello @Ritian-Li thanks for asking your question here.

By default the concrete backend uses 128 bit of security, there is not possibility to change this for now.

In the context of concrete-ml n_bits defines the number of bits used to do the quantization.
For more resources on quantization you can refer to:
