number_ciphertext_elements: The ring elements of a ciphertext

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

The ring elements of a ciphertext

Description

A ciphertext is a list of ring elements: two when fresh, three after a multiplication that has not been relinearized.

Usage

number_ciphertext_elements(ct)

get_elements(ct)

get_elements_mutable(ct)

set_elements(ct, elements)

set_elements_move(ct, elements)

remove_element(ct, index)

Arguments

ct	A Ciphertext.
elements	A list of DCRTPoly objects.
index	Integer; which element to remove, counting from 1.

Details

number_ciphertext_elements() counts them. get_elements() returns copies of them as a list of DCRTPoly handles, and set_elements() replaces the elements of a ciphertext with copies of the ones given. remove_element() deletes one. get_elements_mutable() and set_elements_move() are the names openfhe-python gives to the same two operations; in R, as in Python, they exchange copies.

Value

number_ciphertext_elements(): an integer. get_elements() and get_elements_mutable(): a list of DCRTPoly objects. The others return ct, invisibly.
