以下是RSA算法同态验证的Python代码：

导入RSA模块

from Crypto.PublicKey import RSA

生成RSA公钥和私钥

key = RSA.generate(2048)

获取公钥和私钥

public_key = key.publickey() private_key = key

定义加密函数和解密函数

def encrypt(m, pub_key): return pub_key.encrypt(m, 32)[0]

def decrypt(c, pri_key): return pri_key.decrypt(c)

定义乘法同态函数

def homomorphic_multiply(a, b, pub_key): # 加密a和b ea = encrypt(a, pub_key) eb = encrypt(b, pub_key) # 计算eaeb ec = ea * eb % pub_key.n # 解密ec c = decrypt(ec, private_key) # 返回ab和解密后的结果 return a * b, c

测试乘法同态函数

a = 123 b = 456 c, d = homomorphic_multiply(a, b, public_key) print("a*b =", c) print("e(a)*e(b) =", d) print("乘法同态验证结果：", c == d
