I am trying to use the NTT-based polynomial multiplication implementation in the TFHE-rs library to improve polynomial multiplication time with a 56-bit prime modulus. However, I have found that the TFHE-rs library uses a default q value of 64 bits for computations. I tried to change the modulus q value by calling the function.
CiphertextModulus::try_new(mod_value).unwrap().
Calling the above function only works locally; its value is not reflected globally. I have confirmed the same from the computed result obtained after the modulus operation, which is a 64-bit value calculated using the default value of the TFHE-rs library, not the modulus value I set. So I need some help regarding setting the modulus value in the TFHE-rs library. If anyone point out proper way to set the modulus q value globally that will the be a great help. Also, any suggestion to set modulus q value will be a great help. Thank you for your help.
Hello @Tikaram_Sanyashi
Could you share your code so that we can take a look and see how we can assist ?
