Normally, all data and signaling is encrypted. However, under some circumstances (e.g. emergency calls, when the UE is not registered in the serving network), no encryption keys can be derived and so no encryption is applied—in this case the algorithm is called NULL. \r\n\r\nSeveral procedures and interfaces can be implemented incorrectly or misused and may result in use of the NULL encryption algorithm to protect user signaling -- Non-Access Stratum (NAS) or Access Stratum (AS) Control Plane (CP) -- ; or user data -- AS User Pane (UP) -- over the radio interface. These can be followed by another adversarial behavior whereby eavesdropping can be done over the air interface for data and signaling.",
