Abstract
In some implementations, a policy control function (PCF) device may receive a PCF device key uniquely associated with a user equipment (UE). The PCF device may generate an integrity key and an encryption key based on the PCF device key and an identifier of the PCF device. The PCF device may generate, based on the integrity key, integrity data associated with policy information related to the UE. The PCF device may encrypt, based on the encryption key, the policy information to generate encrypted policy information. The PCF device may send, for the UE, a UE policy message indicating the integrity data, the encrypted policy information, and the identifier of the PCF device.
