serialize_eval_bootstrap_key: Serialize the keys CKKS bootstrapping uses

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

Serialize the keys CKKS bootstrapping uses

Description

serialize_eval_bootstrap_key() writes to a file the automorphism keys that bootstrapping with slots slots uses, out of those registered for cc under key_tag. deserialize_eval_bootstrap_key() reads such a file into the registry: with cc and slots, the keys that bootstrapping setup asks for; without cc, the keys with the automorphism indices in index_list.

Usage

serialize_eval_bootstrap_key(filename, cc, key_tag, slots, format = "binary")

deserialize_eval_bootstrap_key(
  filename,
  cc = NULL,
  key_tag,
  slots = NULL,
  index_list = NULL,
  format = "binary"
)

Arguments

filename	Path to the file.
cc	A CryptoContext on which eval_bootstrap_setup() has been called. For deserialize_eval_bootstrap_key(), NULL to select keys by index_list.
key_tag	Character string; the key tag.
slots	Integer; the number of slots.
format	"binary" (default) or "json"
index_list	Integer vector of automorphism indices; used when cc is NULL.

Value

TRUE on success, FALSE otherwise.
