Abstract
The invention describes a method for transmission of a DHCP message between a telecommunication network, especially a telecommunication network according to the WiMAX-standard, and an Internet Protocol (IP) subscriber (SS/MS; MN) to the telecommunication network. Therein, an information secured with an encryption key is added to the DHCP message. The encryption key is derived from a basic key being provided by a network component of the telecommunication network.
Claims18
A method for transmission of a dynamic host configuration protocol message between a dynamic host configuration protocol server of a telecommunication network and an Internet protocol subscriber device connected to the telecommunication network, the method comprising:
- adding information secured with an encryption key to the dynamic host configuration protocol message by the dynamic host configuration protocol server or by a dynamic host configuration protocol relay arranged between the Internet protocol subscriber device and the dynamic host configuration protocol server, the dynamic host configuration protocol relay configured to relay the dynamic host configuration protocol message from the Internet protocol subscriber device to the dynamic host configuration protocol server;
- wherein the encryption key is derived from a basic key provided by a further server of the telecommunication network, and
- wherein the basic key is a specific key to the dynamic host configuration protocol server.
A telecommunication network component for transmission of a dynamic host configuration protocol message between a dynamic host configuration protocol server of a telecommunication network and an Internet protocol subscriber device connected to the telecommunication network, the telecommunication network component configured to
- add information secured with an encryption key to the dynamic host configuration protocol message received from the Internet protocol subscriber device or to the dynamic host configuration protocol message transmitted to the Internet protocol subscriber device, and
- derive the encryption key from a basic key provided by a further server of the telecommunication network,
- wherein the basic key is a specific key to the dynamic host configuration protocol server.
