Understanding 3G Security Architecture

Before diving into attacks, it's essential to understand the 3G security architecture and its components. This knowledge forms the foundation for effective security testing.

Key Security Components in 3G

Authentication
UMTS AKA (Authentication and Key Agreement) with mutual authentication between network and device.
Encryption
KASUMI block cipher (f8 algorithm) for confidentiality and f9 for integrity protection.
Subscriber Identity
IMSI (permanent identity) and TMSI (temporary identity) with enhanced protection compared to 2G.
Signaling Security
SS7 and Diameter protocols for signaling, with some improvements over 2G but still vulnerable.
USIM Security
Enhanced SIM card (USIM) with improved security features and algorithms.
