Latest Patents
Ralf Berger holds a patent for "Access control for a wireless network." This invention relates to techniques for restricting access to a wireless network for mobile devices. The patent introduces an additional cross-checking functionality on a comparator of an intermediate node. The mobile device receives a user key that indicates general validation to access the WLAN of a third party. The third party operates a key server that issues a key pair, consisting of the user key and an operator key. The operator key is sent to the intermediate node and processed by a processor. The mobile device applies the received user key to an identification set, identifying the device's user, and sends a reference message to the intermediate node via a second communication channel. Subsequently, the device sends its identification set via another first communication channel for authentication and cross-checking to the intermediate node. The intermediate node applies the received operator key to the received message and compares a validation result with the identification set received via the first communication channel. The WLAN network access for the device is granted only in case of identity verification.
