⽤C#实现AES-128CMAC算法公司有个lora项⽬,要⽤到Lora-ns,虽然有其他公司现成的解决⽅案,但是需要有我们⾃⼰的个性化逻辑,因此需要重新⼿写NS的相关代码,根据semtech公司制定的协议标准编写了C#版本的lora-ns。其中⾥⾯有个AES128-CMAC在⽹上⽐较少,我也只在StackOverflow上找到了对应的算法逻辑,...
在C#中实现AES128-CMAC(Cipher-based Message Authentication Code)加密算法,你可以遵循以下步骤: 1. 理解AES128-CMAC的原理 AES128-CMAC是一种基于分组密码(如AES)的消息认证码,用于验证消息的完整性和真实性。它通过对消息进行一系列特定的加密操作,生成一个固定长度的认证码。 2. 查找C#中实现AES128-CMAC的库...

and HMAC is based on a hash function, such as SHA-1, AES-CMAC is appropriate for information systems in which AES is more readily available than a hash function. This memo specifies the authentication algorithm based on CMAC with AES-128. This new authentication algorithm is named AES-CMAC....
This memo specifies an authentication algorithm based on CMAC with the 128-bit Advanced Encryption Standard (AES). This new authentication algorithm is named AES-CMAC. The purpose of this document is to make the AES-CMAC algorithm 展开
