Abstract:
A first cryptographic key (318) and a second cryptographic key (322) are created by a mobile radio terminal (103) and by a computer of the home communications network (108, 109) by using authentication key materials (312). The first cryptographic key (318) is transmitted to the computer of the visited communications network (113), and the second cryptographic key (322) is transmitted to an application server computer (106, 107).
