Здравствуйте, я пытаюсь реализовать программу, которая будет генерировать CSV-файл с банковскими транзакциями и вычислять общее сложение суммы, а затем также вычислять ее с использованием гомоморфного шифрования, но мои выходные данные при гомоморфном шифровании всегда зашифрованы.
Вот код:
import tkinter as tk
from tkinter import filedialog
import csv
import random
import time
from lightphe import LightPHE
def generate_and_write_transactions(filename, num_transactions):
transactions = []
for _ in range(num_transactions):
amount_received = round(random.uniform(10, 500), 2)
transactions.append(("Deposit", amount_received))
with open(filename, "w", newline="") as csvfile:
csvwriter = csv.writer(csvfile)
csvwriter.writerow(["Transaction Type", "Amount"])
csvwriter.writerows(transactions)
def compute_total_amount():
try:
start_time = time.time()
filename = "transaction_history.csv"
total_amount = 0
with open(filename, 'r') as file:
reader = csv.reader(file)
next(reader) # Skip header row
for row in reader:
if row[0] == 'Deposit':
total_amount += float(row[1])
end_time = time.time()
result_label.config(text=f"Total amount (traditional computation): ${total_amount:.2f}\nTime taken: {end_time - start_time:.6f} seconds")
except Exception as e:
result_label.config(text="Error: " + str(e))
def compute_total_amount_homomorphic():
try:
start_time = time.time()
filename = "transaction_history.csv"
cs = LightPHE(algorithm_name="Paillier")
encrypted_values = []
with open(filename, 'r') as file:
reader = csv.reader(file)
next(reader)
for row in reader:
if row[0] == 'Deposit':
encrypted_amount = cs.encrypt(plaintext=float(row[1]))
encrypted_values.append(encrypted_amount)
# Homomorphically add all encrypted values together
total_encrypted_sum = encrypted_values[0]
for encrypted_amount in encrypted_values[1:]:
total_encrypted_sum += encrypted_amount
# Decrypt the total sum
total_sum_decrypted = cs.decrypt(total_encrypted_sum)
total_sum_str = str(total_sum_decrypted) # Represent the decrypted sum as a string
end_time = time.time()
result_text = f"Total amount (homomorphic encryption): {total_sum_str}\nTime taken: {end_time - start_time:.6f} seconds"
result_label.config(text=result_text)
except Exception as e:
result_label.config(text="Error: " + str(e))
generate_and_write_transactions("transaction_history.csv", 10)
root = tk.Tk()
root.title("Bank Account testing")
root.geometry("400x300")
compute_button = tk.Button(root, text="Compute Total Amount (Traditional)", command=compute_total_amount)
compute_button.pack(pady=5)
compute_homomorphic_button = tk.Button(root, text="Compute Total Amount (Homomorphic)", command=compute_total_amount_homomorphic)
compute_homomorphic_button.pack(pady=5)
result_label = tk.Label(root, text="")
result_label.pack()
root.mainloop()
