Jun Guo · Journal of Hebei Normal University · 2009
Let F(n)q2 be the n-dimensional unitary space over the finite field Fq2 and let P be the m-dimensional tolally isotropic subspace of F(n)q2.The number of r-dimensional tolally isotropic subspaces Q such that dim(P∩Q)=i is computed.Furthermore,some authentication codes are constructed using the subspaces of F(n)q2.
