Methods and Apparatuses Generating a Radio Base Station Key in a Cellular Radio System |
| 摘要 |
A Terminal Identity Token is created for identifying a User Equipment (UE) connected to a radio base station in a radio system. The UE communicates with the radio base station via a secure communication associated with an existing cryptographic key. The Terminal Identity Token is created based on a physical cell identity of a target cell known to both the UE and the radio base station, the terminal identity, and the existing key. By using the Terminal Identity Token, a secure communication can be established and enhanced without having to provide for additional security network components or additional signaling. |
