About the decryption correctness problem

[Sherry-user]

Hello, I tried to run the code, but the decryption result is not correct, I don't know why, maybe my understanding is wrong, mainly because the output of "msg" and "phi" in the following part of the code is different, may I ask if you know the specific reason？I wonder if it is caused by too much noise. msg = random.getrandbits(f) phi = np.array([1 & msg >> i for i in range(f)]) print(phi) cipher = timeit(lambda: user.Encrypt(phi, aa.A, aa.b_plus, aa.b_minus), 'Encryption') msg = timeit(lambda: aa.Decrypt(cipher, user.F, user.W), 'Decryption') print(msg)

phi in the result is [0 1 0 1 0 1 1 0 1 1 0 1 0 1 1 1 1 1 1 0 1 0 1 1 0 0 1 0 1 0 0 0 0 1 1 1 1 0 0 1 1 1 0 1 0 1 0 0 0 1 0 1 1 0 0 1 0 1 1 0 0 1 1 1 1 0 1 1 0 1 1 1 1 0 1 0 1 0 1 1 0 1 1 0 1 0 0 1 1 1 0 0 1 0 0 1 1 0 1 1 1 0 0 1 0 0 0 0 0 0 1 0 1 1 0 1 1 1 0 1 1 0 0 0 0 0 1 1 1 0 0 1 1 0 1 1 0 1 0 1 1 0 0 1 1 0 0 1 0 0 0 1 0 0 0 1 1 0 1 1 1 0 1 0 1 0 1 0 0 1 1 1 0 1 1 1 1 1 1 0 1 1 1 1 1 1 0 0 1 1 1 1 0 0 1 0 0 1 1 0 0 0 0 0 1 0 0 0 0 1 1 0 0 1 0 1 1 0 0 1 0 1 1 1 1 1 0 1 0 1 1 1 1 1 0 1 0 0 0 0 1 0 1 1 0 0 1 0 0 0 1 0 1 1 1 0 1 0 1 1 0 1 0 0 1 0 1 1 0 0 0 0 0 0 1 0 0 0 0 1 1 1 0 0 1 0 1 1 1 1 1 0 0 0 0 1 1 1 1 1 0 0 0 0 1 0 1 1 0 1 1 0 1 1 1 0 1 0 0 0 0 0 1 0 1 1 0 0 1 0 0 1 1 1 1 1 0 0 1 1 0 0 1 1 0 1 0 1 0 0 1 0 0 0 1 0 1 0 1 1 1 1 0 1 0 0 1 0 0 0 0 1 0 0 0 1 1 1 1 0 0 1 0 0 1 0 0 1 1 0 0 0 1 0 1 0 1 1 1 0 0 1 1 0 1 1 0 0 1 1 0 1 1 1 0 0 0 1 0 1 1 1 1 1 0 0 1 0 0 1 1 1 1 0 0 0 1 0 0 0 1 0 0 0 0 1 0 1 1 0 0 1 0 0 1 1 1 1 0 1 0 1 1 0 0 0 1 0 1 1 1 1 0 0 0 0 1 1 1 0 0 0 0 0 1 1 0 0 1 0 1 0 1 0 1 0 1 0 1 0 0 0 0 0 1 1 0 0 1 1 1 0] But msg in the run result is [0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 0, 1, 0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0, 1, 0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 1, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 1, 0, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0]
