The security concerns in 3G network, especially the core network, is far from being satisfied. As the most important protocol in the 3G core network, GPRS Tunnel Protocol (GTP) is quite vulnerable to attacks in the flat, full IP environment. Solving such a problem properly is very urgent and important for the operation of 3G network. In this paper, we discus the security issues in GTP, and propose...
Nowadays, 3G netowrk plays a very important role in mobile communication system. But the security concern of such network, especially the core network, is far from being satisfied. GPRS Tunnel Protocol(GTP), which is one of the key protocols in the core network, is quite vulnerable to attacks in the flat, full IP environment. Therefore solving such problem properly is very urgent and important for...
IMSI (International Mobile Station Identity) is a unique number associated with all GSM and UMTS network mobile phone user. IMSI filtering-a prefix filtering, is an important function in the 3G firewall. It is an indefinite filtering which affects the efficiency of the security device. This paper brings forward a parallel processing method which uses vector coding and structure of bloom filter. This...
