cdma2000 system was commercially deployed actively since 2003 last year
supported by 3GPP2. IMT-2000 cdma system was strengthened with cryptographic
algorithms, information security mechanisms, and additional security services
compared to 2nd generation systems. Especially, cdma2000 is characterized by
mutual authentication between user and network and by using strong cryptographic
algorithms. cdma2000 system uses AKA mechanism suggested by 3GPP as an
authentication mechanism and uses SHA-1 for MAC and randomness. This paper
analysed the information security algorithms and authentication mechanisms suggested
by 3GPP2 and made some remarks on that.
