基于密码的消息认证码(Cipher-based Message Authentication Code,简称CMAC)是一种使用对称加密算法来生成消息认证码(MAC)的技术。它确保了消息的完整性和认证,即接收方可以验证消息在传输过程中是否被篡改,并且确认消息确实来自声称的发送方。 2. CMAC的工作原理 CMAC的工作原理基于分组密码(如AES或3DES)的加密操作。
The performance of cipher based MAC techniques depends on the underlying block cipher that is used to calculate the MAC value. For block cipher based MAC schemes, CBC-MAC/XXTEA has been chosen since it has less energy consumption than AES and RC5 and better security strength than skipjack schem...
