Abstract :
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 method is realized in Intel network processor-IXP 2850. The features of parallel multithreads and hash unit in network processor are taken advantages. The experiments show the excellent performance of the method in 3G firewall.
