Abstract
Disclosed herein is a technique for securely provisioning access control entities (e.g., electronic Subscriber Identity Module (eSIM) components) to a user equipment (UE) device. In one embodiment, a UE device is assigned a unique key and an endorsement certificate that can be used to provide updates or new eSIMs to the UE device. The UE device can trust eSIM material delivered by an unknown third-party eSIM vendor, based on a secure certificate transmission with the unique key. In another aspect, an operating system (OS) is partitioned into various sandboxes. During operation, the UE device can activate and execute the OS in the sandbox corresponding to a current wireless network. Personalization packages received while connected to the network only apply to that sandbox. Similarly, when loading an eSIM, the OS need only load the list of software necessary for the current run-time environment. Unused software can be subsequently activated.
