以下是Python代码实现RSA算法同态验证：

导入RSA模块

from Crypto.PublicKey import RSA from Crypto.Cipher import PKCS1_v1_5

定义RSA密钥

key = RSA.generate(2048)

获取公钥和私钥

public_key = key.publickey() private_key = key

加密函数

def encrypt(msg): cipher = PKCS1_v1_5.new(public_key) ciphertext = cipher.encrypt(msg.encode()) return ciphertext

解密函数

def decrypt(ciphertext): cipher = PKCS1_v1_5.new(private_key) message = cipher.decrypt(ciphertext, None) return message.decode()

定义a,b,c的值

a = 123 b = 456 c = a * b

对a,b,c进行加密

e_a = encrypt(str(a)) e_b = encrypt(str(b)) e_c = encrypt(str(c))

对e_c进行解密，验证乘法同态的正确性

if c == int(decrypt(e_a)) * int(decrypt(e_b)): print("验证成功") else: print("验证失败"
