The invention relates to a method for distributing keys to subscribers in communications networks, in particular digital mobile radio networks. These keys are required, for example, for access to added value services. In this case, there is a problem in distributing the keys securely and, above all, in an uncomplicated manner, to the subscribers. According to the invention, this is achieved by the keys being generated, and possibly stored if required, in a security device provided at the mobile radio network end and, on request by a subscriber, by at least one key being requested from the security device, being allocated to the subscriber, and being transmitted via the mobile radio network to the subscriber's mobile station. |
