get_bin_cc_for_scheme_switch: The FHEW side of a scheme-switching context

In openfhe.R: R Interface to the 'OpenFHE' Fully Homomorphic Encryption Library

The FHEW side of a scheme-switching context

Description

get_bin_cc_for_scheme_switch() returns the FHEW context that a scheme-switching setup created inside the CKKS context cc, and set_bin_cc_for_scheme_switch() puts one there. get_swk_fc() and set_swk_fc() read and write the switching key from FHEW to CKKS, which is a CKKS ciphertext. The setters are for restoring a context in another session.

Usage

get_bin_cc_for_scheme_switch(cc)

set_bin_cc_for_scheme_switch(cc, bin_fhe_context)

get_swk_fc(cc)

set_swk_fc(cc, switching_key)

Arguments

cc	A CKKS CryptoContext.
bin_fhe_context	A BinFHEContext.
switching_key	A Ciphertext.

Value

get_bin_cc_for_scheme_switch(): a BinFHEContext, or NULL if cc holds none. get_swk_fc(): a Ciphertext, or NULL if cc holds none. The setters: cc, invisibly.
