Abstract
In private cellular Fifth Generation (5G) deployments, where authentication is required to be performed on premise, a home network secret key (also known as home network private key) that is used to decrypt the SUCI (Subscription Concealed Identifier) of all subscribers needs to be provided to edge networks (generally referred to as the 'edge'). Compromise at any edge regarding the home network secret key can lead to loss of privacy of all subscribers at all enterprise locations and edges. Proposed herein is a technique that enables creating enterprise/edge specific public and secret keys and updating these keys on the UE of mobile devices in such a manner that the SIM/eSIM is not impacted. This provides a safeguard against potential edge compromise scenarios involving private 5G deployments without requiring updates to the SIM/eSIM.
