get_n: Parameters of a BinFHE context

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

Parameters of a BinFHE context

Description

The LWE parameters of a context. OpenFHE names them by letter case, which R function names do not carry: get_n() is the lattice dimension n and get_big_n() the ring dimension N; get_q() is the small ciphertext modulus q and get_big_q() the large modulus Q (the C++ Getn(), GetN(), Getq() and GetQ()). get_beta() is the bound beta in the plaintext space q / (2 * beta).

Usage

get_n(ctx)

get_big_n(ctx)

get_q(ctx)

get_big_q(ctx)

get_beta(ctx)

Arguments

ctx	A BinFHEContext.

Value

get_n() and get_big_n(): an integer. The others: a number, or a string of decimal digits if the value is above 2^53.

Examples

ctx <- bin_fhe_context(BinFHEParamSet$TOY)
c(n = get_n(ctx), N = get_big_n(ctx), q = get_q(ctx), Q = get_big_q(ctx))
