Abstract :
The hidden security troubles of 3G network based on SIP is analyzed. In view of the security demand of 3G and the security bug of AKA protocol adopted in 3G network, an enhanced secure access protocol E-AKA is designed with SIP messages. E-AKA protocol not only effectively avoids the security threat, but also realizes the two-way authentication between the user equipment (UE) and home environment (HE) or serving network (SN). Through agreeing the key, the cipher key (CK) and the integrity key (IK) are generated, and the encryption method of one-session-one-key is realized. The analytic results show that E-AKA protocol can satisfy the need of 3G session protocol developing toward SIP; at the same time, it can ensure the access security of 3G network.
