Main constructor for RingGSWCryptoParams

Parameters

  • N – ring dimension for RingGSW/RLWE used in bootstrapping

  • Q – modulus for RingGSW/RLWE used in bootstrapping

  • q – ciphertext modulus for additive LWE

  • baseG – the gadget base used in the bootstrapping

  • baseR – the base for the refreshing key

  • method – bootstrapping method (DM or CGGI or LMKCDEY)

  • std – standar deviation

  • keyDist – secret key distribution

  • signEval – flag if sign evaluation is needed

  • numAutoKeys – number of automorphism keys in LMKCDEY bootstrapping

void PreCompute(bool signEval = false)
