摘要： The invention relates to techniques for restricting a wireless network access for a mobile device (200). There is provided an additional cross-checking functionality on a comparator (106) of an intermediate node (100). The mobile device (200) receives a user key (88) indicating a general validation to access the WLAN of a third party. The third party operates a key server (300). The key server (300) issues a key pair, consisting of the user key (88) and an operator key (99). The operator key (99) is sent to the intermediate node (100) and is processed by a processor (105). The mobile device (200) applies the received user key (88) to an identification set (200i), identifying the device's user, and sends a reference message (22) to the intermediate node (100) via a second communication channel (2). Thereinafter, the device (200) sends its identification set (200i) via another first communication channel (1) for authentication and for cross checking to the intermediate node (100). The intermediate node (100) in turn applies the received operator key (99) to the received message (22) and compares a validation result (33) thereof with the identification set (200i), received via the first communication channel (1). The WLAN network access for the device is only granted in case of identity.

摘要： The invention relates to a method to process data packets of a vehicle message received by a privacy gateway (100) from a vehicle (10) via a mobile communications network (20). The method comprises the following steps: The vehicle message transmitted by the vehicle (10) is received. A source IP address in the data packets of the vehicle message is identified. The source IP address in the data packets of the vehicle message is replaced by an IP address of a location collecting entity (50) of the mobile communications network (20). Said mobile communications network collects location information of a plurality of vehicles (10) resulting in an adapted vehicle message with adapted data packets containing the IP address of the location collecting entity as source IP address. Then, the adapted vehicle message is transmitted to a service providing entity (40) which is configured to provide location dependent services for the plurality of vehicles.

摘要： A user device (10) provides a subscriber with access to a network service. The user device (10) determines service-specific key material and charging-specific key material. The user device (10) determines a charging record indicating usage of the network service by the subscriber and associates the charging record with first authentication information based on the charging-specific key material. The user device (10) generates at least one message including the charging record and the associated first authentication information. The user device (10) associates the at least one message with second authentication information based on the service-specific key material. The user device (10) sends the at least one message to a first network node (150) which is incapable of relating the charging-specific key material or the service-specific key material to a subscriber identity of the subscriber. The first network node (150) receives the at least one message and the associated second authentication information from the user device (10) and authenticates the at least one message based on the service-specific key material and the second authentication information. In response to authenticating the at least one message, the first network node forwards the charging record and the associated first authentication information to a second network node (120). The second network node (120) is capable of relating the charging-specific key material to the subscriber identity of the subscriber. The second network node (120) receives the charging record and the associated first authentication information from the first network node (150) and authenticates the charging record based on the charging-specific key material and the first authentication information. In response to authenticating the charging record, the second network node (120) controls charging of the network service.

摘要： A network node initiates a multicast transmission of a data item via a cellular network to a plurality of devices. Associated with the multicast transmission, the network node provides a request that at least a subgroup of the devices each send a report indicating whether an action on the basis of the data item received by the device was successfully completed by the device. Depending on the reports, the network node adjusts the repeated multicast transmission of the data item.

摘要： A technique for controlling cryptographic document protection and verification is presented. In one implementation, a device is associated with a device identifier and with a cryptographic key is configured to obtain an electronically processable document representation (EPDR) of content of a document that is to be protected and to apply the cryptographic key to the EPDR to obtain a cryptographically processed document representation (CPDR). The device is further configured to transmit the device identifier and a verification parameter comprising at least one of the EPDR and the CPDR towards a transaction server that is configured to log the device identifier and the verification parameter in a tamper-proof manner. The device is also configured to receive a transaction identifier associated with the device identifier and the verification parameter from the transaction server, and trigger printing of the transaction identifier and the CPDR on a physical document that corresponds to the EPDR.
