1. A method comprising:
sending, by a base station, a root key to an access node;
identifying, by the base station, an encryption algorithm to be used by the access node;
sending, by the base station, the encryption algorithm of the access node to a user equipment (UE);
receiving, by the base station and from the UE, signaling indicating that the UE has derived an encryption key according to the root key and the encryption algorithm; and
in response to receiving the signaling, indicating, by the base station, the access node to perform downlink encryption and uplink decryption.
