Abstract
Mobile network services are performed in a mobile data network in a way that is transparent to most of the existing equipment in the mobile data network. The mobile data network includes a radio access network and a core network. A breakout component in the radio access network breaks out data coming from a basestation, and performs one or more mobile network services at the edge of the mobile data network based on the broken out data. These services may require the use of keys. Keys are stored and retrieved from a non-volatile key storage in a way that assures subsystems that need the keys have access to the keys. The keys retrieved from the non-volatile key storage are stored in a shared memory in the requesting subsystem, which allows any applications that requires access to the keys to directly access the keys in the shared memory.
