multi_key_switch_gen: Multi-party key-switch eval-key generation
In openfhe.R: R Interface to the 'OpenFHE' Fully Homomorphic Encryption Library
multi_key_switch_gen R Documentation
Multi-party key-switch eval-key generation
Description
Generates an eval key that switches ciphertexts encrypted
under sk_orig into a form decryptable by sk_new, starting
from an existing eval key that carries the key-switch
auxiliary information. Used by threshold protocols to route
partial decryptions across a re-keyed party set.
Usage
multi_key_switch_gen(cc, sk_orig, sk_new, eval_key)
Arguments
cc
A CryptoContext
sk_orig
The original party's PrivateKey
sk_new
The new party's PrivateKey
eval_key
An EvalKey carrying key-switch auxiliary data
Value
An EvalKey suitable for routing through
multi_add_eval_keys() to combine with other parties'
key-switch shares
