Abstract
A method for reducing calculation time for processing fully homomorphic encrypted (FHE) data comprises pre-calculating a second half of a key-switching key, storing the second half of the key-switching key in memory, and receiving FHE data. After the FHE data is received, the method determines a first half of the key-switching key by randomly generating a first half of the key-switching key. The key-switching key is then constructed by retrieving the second half of the key-switching key from the memory and appending the second half of the key-switching key to the first half of the key-switching key. After the key has been constructed, a key-switching operation is performed on the FHE data using the key-switching key.
