摘要
消息认证码(Message Authentication Code,MAC)是密码学中一个重要的研究方向,它是保证消息完整性的基本算法,被广泛应用于各种安全系统中。本文研究了各种消息认证码,对当前流行的MAC进行了分类,介绍了它们各自的构造方法及优缺点,并对某些MAC进行了比较,最后提出了进一步可做的工作。
In modern cryptography, Message Authentication Codes are very important, which provide data integrity and are used in all kinds of security systems. In this paper, we have divided popular MACs into two classes. Their constructions and performances are introduced. Finally, future research and promising research prospect are indicated.
