METHOD FOR PROTECTING AN INTERNET SUPPLEMENTARY SERVICE

摘要

The invention relates to a method for improving the security of an Internet supplementary service. When access to the IP server network of a network operator is sought for an ISS message from the Internet, a service-independent authorisation procedure is carried out by a purpose-built security server, a service-independent identification being used to obtain said authorisation. A service-related authorisation procedure is subsequently carried out by a service access server, by means of a user password.
