Boolean FHE (BinFHE) documentation

Refer to our OpenFHE-Readthedocs for more information. This folder contains implementations of Ducas-Micciancio (FHEW), Chillotti-Gama-Georgieva-Izabachene (TFHE) and [Lee-Micciancio-Kim-Choi-Deryabin-Eom-Yoo(LMKCDEY)] (https://eprint.iacr.org/2022/198).

Binary FHE CryptoContext

• CryptoContext for the boolean circuit FHE scheme
• A CryptoContext is the primary object through which we interact with the various OpenFHE capabilities

Binary FHE CryptoContext Serialization

• Adds serialization support to Bollean Circuit FHE

DM/CGGI Cryptosystem

• The main cryptosystem implementation used for DM/CGGI schemes
• The scheme is described in Bootstrapping in FHEW-like Cryptosystems from Daniele Micciancio and Yuriy Polyakov as published in Cryptology ePrint Archive, Report 2020/086
• The Ring GSW accumulator implementation with AP, GINX and LMKCDEY methods for bootstrapping

Constants for DM/CGGI Cryptosystem

• Defines all options for BINFHE_PARAMSET (security levels for predefined parameter sets), BINFHE_METHOD (bootstrapping method), BINFHE_OUTPUT (type of ciphertext generated by encryption), BINGATE (type of gates supported, either with two or more inputs), and KEYGEN_MODE (secret or public key encryption) enums

Parameters for DM/CGGI Cryptosystem

• The parameters for LWE and Ring GSW schemes

LWE CryptoParameters

• Class for all LWE parameters used for boolean FHE

Ring GSW CryptoParameters

• Class for all RGSW parameters used for boolean FHE bootstrapping

LWE public-key scheme

• Additive LWE scheme with public-key encryption

LWE Ciphertext

• Class for LWE ciphertext for boolean FHE

RLWE Ciphertext

• Class for RLWE ciphertext for boolean FHE

LWE secret key

• Class for the secret key of the LWE scheme

LWE public key

• Class for the public key of the LWE scheme, in the case where asymmetric encryption is desired

LWE Keypair

• Classes for the key pair of private and public key, in the case where asymmetric encryption is desired

LWE switching key

• Class for the switching key of the LWE scheme

Ring GSW accumulator

• The main accumulator class for bootstrapping. The different methods are described in:
• (rgsw-acc-cggi.h) for CGGI method
• (rgsw-acc-dm.h) for DM method
• (rgsw-acc-lmkcdey.h) for LMKCDEY method

Ring GSW accumulator key

• Class for the bootstrapping key

Ring GSW evaluation key

• Class for the internal RGSW scheme used in bootstrapping
