Abstract
A device may receive, from a network device, a user equipment (UE) parameter update request notification indicating an update to a UE parameter of a universal subscriber identity module (USIM), and may generate an encrypted UE parameter update request. The device may cause the encrypted UE parameter update request to be provided to the USIM to cause the USIM to update the UE parameter and to generate an encrypted UE parameter update response. The device may receive, from the network device, the encrypted UE parameter update response, and may verify an authenticity of content of the encrypted UE parameter update response based on whether the encrypted UE parameter update response is signed by the USIM. The device may provide, to the network device, a result indicating whether the UE parameter is updated and whether the authenticity of the content of the encrypted UE parameter update response is verified.
