In LTE, if a NAS packet is going to be sent, the encryption is followed by integrity protection in NAS layer, but in RRC/PDCP layer, When RRC messages are being sent, they are integrity protected first and then encrypted before being sent, unlike NAS messages were. Why the integrity and encryption protection order is different in NAS and AS layer?
