Ciphering is the process of altering voice or data information with the intention of preventing its consumption or usage by unauthorized recipients . … Without the encryption algorithm and key(s), unauthorized listeners cannot decode the data or messages.
Read moreWhat is ciphering in GSM?
GSM makes use of a ciphering key to protect both user data and signaling on the vulnerable air interface . Once the user is authenticated, the RAND (delivered from the network) together with the KI (from the SIM) is sent through the A8 ciphering key generating algorithm, to produce a ciphering key (KC).

The new 5G system brings high demands on cryptographic algorithms used for air encryption. Ericsson Research together with Lund University have revised the design of SNOW 3G and updated it to a new faster cipher called SNOW-V , which could be used to secure 5G and the coming mobile systems.
Read moreWhat are the ciphering and integrity algorithms available in LTE?
Possible algorithms are: 128-eia0: Null ciphering algorithm (128-EIA0) for LTE integrity as the integrity algorithm for security procedures. 128-eia1: SNOW 3G synchronous stream ciphering algorithm (128-EIA1) for LTE integrity as the integrity algorithm for security procedures.
Read moreWhat is integrity key and ciphering key?
While integrity check is a mandatory function, ciphering is an optional function. NAS security keys, such as integrity key (KNASint) and ciphering key (KNASenc), are derived by UEs and MMEs from K ASME. AS Security. AS security is purposed to ensure secure delivery of data between a UE and an eNB over radio links.

Ciphering Ciphering, also known as encryption, ensures that intruders cannot read the data and signalling messages that the mobile and network exchange . Ciphering can be applied to both U-Plane Data and C-Plane Data (RRC/NAS Message).
