Abstract
A very efficient authentication and authorization check in n:m relationships is possible with a method for checking the entitlement of a user of a telecommunication terminal () to a service, whereby an access device () on a telecommunication network () obtains at least one certificate and a proof of identity () from the telecommunication terminal (), whereupon NMT () together with a certification device () carries out a check of whether the certificate giving the identity is valid and has a positive status and whether particular authorization may be obtained from complementary certificates. Should the above be the case, a secret (for example a session key) is transmitted () to the access device () which is also sent () to the telecommunication terminal (), encoded with at least the public key. The access device () is then activated with a policy corresponding to the rights of the telecommunication user.
