Milenage Security

A technical overview

Saturn Eclipse provide support to understand and develop the Milenage algorithm set.

In 3rd and 4th generation mobile networks, communications are secured using an algorithm set called ‘Milenage’. Milenage is a collection of cryptographic functions that provide authentication, encryption and integrity between SIM cards and a mobile core network. 

NAS Security

The NAS protocol layer provides signalling between the UE and core network. NAS messages are ciphered and integrity protected between the UE and MME.

AS Security

AS security is used to protect communications over-the–air between UE and eNodeB. RRC messages are integrity protected and ciphered but U-plane data is only ciphered.
