Paillier Encryption Scheme

Install

You need install boost in advance.

cd paillier
pip install -e .

Usage

Key generation

>>> from aijack_paillier import PaillierKeyGenerator
>>> keygenerator = PaillierKeyGenerator(512)
>>> pk, sk = keygenerator.generate_keypair()

>>> pk.get_publickeyvalues()

Encrypt & Decrypt

>>> ct_1 = pk.encrypt(13)
>>> pk.decrypt4int(ct_1)
13

Arithmetic operation

>>> ct_2 = ct_1 * 2
>>> pk.decrypt4int(ct_2)
26

>>> ct_3 = ct_1 + 5.6
>>> sk.decrypt2float(ct_3)
18.6

>>> ct_4 = pk.encrypt(18)
>>> ct_5 = ct_1 + ct_4
>>> sk.decrypt2int(ct_5)
31
