| Abstract: | By using subspaces of symplectic geometry,we construct one type of non-Cartesion authentication code,and compute its size parameters. Moreover, assuming that the encoding rule is chosen according to a uniform probability distribution,we also compute the probabilities of a successful impersonation attack and of a successful substitution attack respectively. |
