| Abstract: | Some problems about unconditionally secure authentication code in the papers 1]and 2]which base on error-correcting code are described. Some uncoditionally secure authentication codes in constructed by using the error-correcting code and finite geometries. One new method of embeding subliminal channel into Cartesian authentication code is proposed. |
