Abstract
Methods for carrying out an authentication check in a mobile telephone system in which an authentic base station serves a plurality of mobile stations. A prior method carried out a unidirectional check from the base to a calling mobile permitting a false base to carry out a false authentication check by collecting a number of so-called RAND-Response pairs. To avoid this problem another unidirectional base-to-mobile authentication check and an authentication check from the mobile to the base are carded out. In one embodiment only the bi-directional authentication check is carried out.
