hadamard_multiply

GLEngine.hadamard_multiply(x, y, hadamard_multiplication_key)

두 3차원 행렬의 아다마르 곱셈을 수행한 암호문을 반환합니다. 레벨을 소모합니다.

• 인풋:
  • x: double 혹은 complex double의 3차원 행렬, GLPlaintext, 혹은 GLCiphertext
  • y: double 혹은 complex double의 3차원 행렬, GLPlaintext, 혹은 GLCiphertext
  • 인풋 둘 중 하나는 암호문이어야 합니다.
  • HadamardMultiplicationKey, optional
    • 두 인자가 모두 암호문인 경우에 필요합니다.
• 아웃풋:
  • GLCiphertext

Examples

암호문 간 아다마르 곱셈

import numpy as np

from desilofhe import GLEngine

engine = GLEngine()
shape = engine.shape
secret_key = engine.create_secret_key()
hadamard_multiplication_key = engine.create_hadamard_multiplication_key(
    secret_key
)

message1 = np.ones(shape, dtype=np.float64)
ciphertext1 = engine.encrypt(message1, secret_key)

message2 = np.ones(shape, dtype=np.float64) * 2
ciphertext2 = engine.encrypt(message2, secret_key)

multiplied = engine.hadamard_multiply(
    ciphertext1, ciphertext2, hadamard_multiplication_key
)

암호문과 3차원 행렬의 아다마르 곱셈

import numpy as np

from desilofhe import GLEngine

engine = GLEngine()
shape = engine.shape
secret_key = engine.create_secret_key()

message1 = np.ones(shape, dtype=np.float64)
ciphertext1 = engine.encrypt(message1, secret_key)

message2 = np.ones(shape, dtype=np.float64) * 2
ciphertext2 = engine.encrypt(message2, secret_key)

multiplied1 = engine.hadamard_multiply(ciphertext1, message2)
multiplied2 = engine.hadamard_multiply(message1, ciphertext2)

암호문과 평문간 아다마르 곱셈

import numpy as np

from desilofhe import GLEngine

engine = GLEngine()
shape = engine.shape
secret_key = engine.create_secret_key()

message1 = np.ones(shape, dtype=np.float64)
plaintext1 = engine.encode(message1)
ciphertext1 = engine.encrypt(plaintext1, secret_key)

message2 = np.ones(shape, dtype=np.float64) * 2
plaintext2 = engine.encode(message2)
ciphertext2 = engine.encrypt(plaintext2, secret_key)

multiplied1 = engine.hadamard_multiply(ciphertext1, plaintext2)
multiplied2 = engine.hadamard_multiply(plaintext1, ciphertext2)
