Abstract
A base key that is stored at a device may be received. A network identification may further be received. A device identification key may be generated based on a combination of the network identification and the base key. Furthermore, the device identification key may be used to authenticate the device with a network that corresponds to the network identification.

1-20. (canceled)
A method comprising:
- receiving a base key being stored at a device;
- receiving a mobile communications network identification;
- generating, by a processing device, a device identification key based on a combination of the mobile communications network identification and the base key;
- and
- using the device identification key to authenticate the device with a mobile communications network corresponding to the mobile communications network identification.
A system comprising:
- a memory to store a base key;
- and
- a processing device coupled with the memory to:
- retrieve the base key being stored at the memory;
- receive an identification of the mobile communications network;
- and
- generate a device key based on the base key and the identification of the mobile communications network, wherein the device key is associated with authenticating the device for use with a mobile communications network corresponding to the mobile communications network identification.
A non-transitory computer readable medium including data that, when accessed by a processing device, cause the processing device to perform operations comprising:
- receiving a base key being stored at a device;
- receiving a mobile communications network identification;
- generating a device identification key based on a combination of the mobile communications network identification and the base key;
- and
- using the device identification key to authenticate the device with a mobile communications network corresponding to the mobile communications network identification.
