Summary: | The invention relates to a method for using a service of a mobile packet core network in a communication system comprising a mobile device, a node, a mobile packet core network and a wireless radio access network, whereby the mobile device accesses the mobile packet core network via the wireless radio access network, whereby the mobile device during a setup of a connection of the mobile device to the wireless radio access network determines whether the wireless radio access network is a trustworthy wireless radio access network and at least if the wireless radio access network is not trustworthy establishes a secure tunnel connection to the node of the communication system for triggering a usage of the service of communiation system by an authentication entity, which is characterized in that the secure tunnel connection is established by using a token stored within the mobile device and received from the mobile device by the node, whereby the token comprises at least a certificate for authentication to the authentication entity, a MSISDN (MSISDN: Mobile Subscriber Integrated Services Digital Network) respectively a virtual MSISDN (vMSISDN) and an IMSI (IMSI: International Mobile Subscriber Identity) respectively a virtual IMSI (vIMSI) allocated to the user of the mobile device and whereby the token is generated by the node using general security mechanisms, in particular TPM (TPM: Trusted Platform Module) and/or MD5 (MD5: Message-Digest Algorithm 5). |
