[Dive into 5G] Ciphering and Integrity Protection over the 5G Air Interface:
1 Purpose
This document answers the following questions:
What are the major security threats to the 5G air interface, for example, data eavesdropping or tampering?
What measures can be taken to prevent data from being eavesdropped on or tampered with, for example, ciphering and integrity protection over the air interface?
What are the key technologies of ciphering and integrity protection over the air interface, for example, key lifecycle management and security algorithms?
Why do we need to perform hierarchy generation and mobility management of keys?
What are the differences between and priorities of ciphering and integrity protection algorithms over the air interface?
