Systems and methods for provisioning user privacy parameters necessary for network security in 5G telecommunication networks are provided, such as the subscriber permanent identifier (SUPI), the routing indicator, the protection scheme identifier, or the home network key. In order to protect the user privacy parameters, the techniques disclosed herein use private and public key encryption, as well as integrity protection offered by 5G telecommunications protocols. Such techniques use registration response messages, update location requests, or update notification request messages to provide end-to-end or end-to-middle security in the provisioning process. Unlike existing over-the-air (OTA) techniques, the techniques described herein provision user privacy parameters or other similar data in a secure and verifiable manner.
