摘要
文章总结了消息鉴别码和数字签名方案之间的关联,比较了两者之间在方案定义、安全定义,通用构造方法的相似之处和区别。这些对比有利于学习者对这两种密码学方案的学习和领会,也有利于教学者讲授这两种方案。
This article summarizes the relations between message authentication code and digital signature. The similarity and distinction between both are compared such as scheme definition, security definition, and general construction methods. The review helps learners to understand two schemes, and it also facilitates instructors to teach two schemes.
