Abstract
A user equipment (UE) may receive, from a certificate authority, a first onboarding identifier associated with a private key stored on the UE. The UE may transmit, to a wireless network, an attach request based on the first onboarding identifier. The UE may receive, from the wireless network, a signaling message that includes a second onboarding identifier, wherein the signaling message may be encrypted with a public key paired with the private key stored on the UE. The UE may decrypt the signaling message using the private key stored on the UE to obtain the second onboarding identifier. The UE may obtain a permanent identifier from a Remote SIM Provisioning platform based on the UE completing an authentication procedure using an authentication response obtained from the decrypted signaling message. The UE may then connect to the wireless network using the permanent identifier.
