Some Anzahl Formulas in Finite Unitary Spaces and Their Applications
摘要/Abstract
摘要:
设F(n)q2)是一个Fq2上的n维酉空间,P是任一个给定的m维全迷向子空间。计算了F(n)q2中满足dim(P∩Q)=i的r维全迷向子空间Q的个数,给出了用子空间构作认证码的例子。
Abstract:
Let F(n)q2 be the n -dimensional unitary space over the finite field Fq2 and let P be the m-dimen -sional tolally isotropic subspaceofF(n)q2 . The number of r-dimensional tolally isotropic subspaces Q such that dim(P H Q)= i is computed. Furthermore, some authentication codes are constructed using the subspaces ofF(n)q2
