virtual void PrecomputeCRTTables(KeySwitchTechnique ksTech, ScalingTechnique scalTech, EncryptionTechnique encTech, MultiplicationTechnique multTech, uint32_t numPartQ, uint32_t auxBits, uint32_t extraBits) override

Computes all tables needed for decryption, homomorphic multiplication and key switching. Even though this is a pure virtual function and must be overriden in all derived classes, PrecomputeCRTTables() has its own implementation in the source file. It should be called from derived classes’ PrecomputeCRTTables() only and must not be called from CryptoParametersRNS::load().

Parameters

  • ksTech – the technique to use for key switching (e.g., BV or GHS).

  • scalTech – the technique to use for scaling (e.g., FLEXIBLEAUTO or FIXEDMANUAL).
