Third Generation (3G) wireless networks are now increasingly being deployed throughout the world. Because of their complex signaling and relatively limited bandwidth, these 3G networks are generally more vulnerable than their wire-line counterparts, thus making them fertile ground for some new attacks. In this paper, we propose a novel AKA Protocol scheme of 3G, which is based on Diffie-Hellman Algorithm. This scheme improves the transmission security between ME, VLR and HLR, it also provides message freshness, forward secrecy, robust message confidentiality and message integrity. Man-in-the-middle attack and replay attack are also prevented. However, it cannot prevent the key compromise impersonation because of the shared key scheme.
