摘要:

构造了两种基于可调分组密码的MAC:TXOR和TPMAC,分别对其带状态的、随机的和确定的算法进行了研究,并且用具体的界刻画了其安全性。

关键词: 分组密码, 可调分组密码, 消息认证码, 工作模式

Abstract:

Two MACs which are based on tweakable block ciphers are constructed:TXOR and PMAC.Then their corresponding stateful,randonmized,and determined algorithms are studied respectively and the concrete security bounds are given.

Key words: block cipher, tweakable block cipher, MAC, mode of operation
