Secure communication mechanisms for GSM networks

With the advance of wireless communications technology, mobile I:ommunication. \ has become lIlure convenient than ever. Hnwcllcr, because of the openness of wireless comlllunication.l, how to prutect the privacy between communicating pa rties is becoming a very important issue. In thi.1 paper, we fucus on the.security of till! Glohal System for Mohile communication (GSM) networks, A secure communication architecture for the GSM ndwork is propused. In the pruposed architecture, we usc public-key cryptography for IHer authentic:ltioll and stream cipher fur message encryption and decryptioll. An authentication protocol and a key gcncnltion method arc presented in conjunction with the propo.sed 'Irchitcctllt·C, Cryptanalysis and operatiollal analysis.Ihnw that the authentication protocol h.WClIfC and efficient. Simulatioll results indicate that the key genuatilln method clIn alway.s produce key striu/;s elf evenly d istrib uted O's and I 's and with int1nitc period
