(Q,o)是一个拟群.如果对(Q,o)中任何两个不同元素x,y皆有x o y≠y o x,则称(Q,o)是反交换的.本文给出一种基于反交换拟群的消息认证码,并讨论反交换拟群的构造方法.
Let(Q,o)be a quasigroup.If for any two different elements x,y in Q,we always have x o y≠y o x,then we say that(Q,o)is anti-commutative.In this paper,we give a new kind of message authentication code based on anti-commutative quasigroups and discuss the constructions of such quasigroups.
