摘　　要：Cartesian认证码在通讯中有重要应用.利用奇异酉空间F(2ν+δ+l)q2构作了一个Cartesian认证码,并计算了这个码的参数、模仿攻击与替换攻击的概率.Cartesian authentication codes have important application in the communication. In this paper,we construct a Cartesian authentication code from subspaces of singular unitary space Fq（2/2v＋δ＋l） and compute its parameters. We also compute the probabilities of impersonation attack and substitution attack under the assumption that impersonation attack and substitution attack are successful.
