HMAC是MAC的一种构造方式,它是基于密码学hash函数的MAC。这意味着还有其它构造MAC的方法,比如基于blockcipher的CMAC。 HMAC的定义: en.wikipedia.org/wiki/H(sometimes,and%20a%20secret%20cryptographic%20key. What is the difference between MAC and HMAC?
Since the attacks on the underlying block cipher can be applied directly to the first block of CMAC, the current security margin is not sufficient compared to what the designers of AES claimed. In this paper, we consider HMAC-DM-AES-128 as an alternative to CMAC-AES-128 and analyze its ...
OPC 统一架构 (OPC UA) 是一个可扩展的 SOA 框架，旨在支持从嵌入式微控制器到云基础设施的各种平台。
当然ssl / tls可以提供保密性和身份验证,但是完整的PKI比hmac或CMAC模式具有更多的开销。 (+1是可靠的建议。) 让Alice生成两个完全随机的密钥进行加密是否更好?即她发送(现在|| K || Ks || Ke),其中Ks和Ke是Alice生成的两个随机的256位密钥,仅用于这样的一次交换。
