Abstract:
1. A method for processing data packets in a mobile data network that includes a radio access network coupled to a core network, the method comprising: a plurality of antennas sending and receiving network messages between user equipment and a plurality of basestations in the radio access network, each basestation communicating with a corresponding one of the plurality of antennas; providing a breakout component in one of the plurality of basestations, the breakout component comprising: writing the keys to the non-volatile key storage in the security subsystem during manufacture of the breakout component with each key having a corresponding key identifier and a corresponding secret value; when an application running on a first subsystem system in the breakout component requires access to a key stored in the non-volatile key storage, the application requesting access to the key from the first subsystem using the key identifier and secret value corresponding to the key, and in response to the request by the application to access the key, the first subsystem retrieving the key from the security subsystem and writing the key to a shared memory in the first subsystem; the application accessing the key in the shared memory; detecting tampering of the breakout component; and in response to a detected tampering of the breakout component, erasing the keys in the non-volatile key storage.
