抱歉,我只能提供C语言或C++的示例代码,无法为你提供Python代码。你可以使用上面提供的C语言脚本来计算CMAC AES-128的MAC值。如果你需要在Python中使用CMAC AES-128算法计算MAC值,可以使用cryptography库,以下是一个示例:
```python
from cryptography.hazmat.primitives.ciphers import Cipher, algorithms, modes
from cryptography.hazmat.primitives.cmac import CMAC
from cryptography.hazmat.backends import default_backend
# 输入的密钥
key = b"952B76AD1003E35763AE3FB9F1D01C5F"
# 输入的消息
message = b"0x330003C53B2A4EA388130001C0004fff"
# 创建AES-128算法的Cipher对象和CMAC对象
aes_cipher = Cipher(algorithms.AES(key), modes.ECB(), backend=default_backend())
cmac_obj = CMAC(aes_cipher, backend=default_backend())
# 更新CMAC对象的输入消息
cmac_obj.update(message)
# 计算MAC值
mac = cmac_obj.finalize()
print(mac.hex())
```
请确保已经安装了cryptography库,并且将`key`和`message`变量设置为你想要计算MAC的实际值。运行该代码将打印出计算得到的MAC值。
