Detailed Description

Defines core enumerations and helper functions for ComputeFHE configuration.

Enumeration Type Documentation

ALUType

enum computefhe::ALUType

Specifies the logic gate implementation strategy.

• ALU_STANDARD: Uses basic FHE gates for logic operations.
• ALU_OPTIMIZED: Uses specialized multi-input gates (like MAJ or XOR3) to reduce the number of bootstrapping operations.

CryptoContextParam

enum computefhe::CryptoContextParam

Supported cryptographic context parameters for OpenFHE.

These values correspond to specific security levels and bootstrapping configurations in OpenFHE.

• GINX: Entries without 'LMKCDEY' use the GINX bootstrapping method (Gama-Izabachène-Nguyen-Xie).
• LMKCDEY: Refers to the bootstrapping scheme proposed by Lee-Micciancio-Kim-Choi-Deryabin-Eom-Yoo.
• 3-input logic: Parameters ending in '_3' enable 3-input gate optimizations.

Function Documentation

ToString() [1/2]

const char * computefhe::ToString ( ALUType  v )

inline

Converts an ALUType value to a human-readable string.

Parameters

v	The ALU type enum.

Returns

A string representation ("STANDARD" or "OPTIMIZED").

ToString() [2/2]

const char * computefhe::ToString ( CryptoContextParam  v )

inline

Converts a CryptoContextParam value to a human-readable string.

Parameters

v	The cryptographic context parameter enum.

Returns

A string representation of the parameter set name.
