In this book, the security algorithms for wireless communications
were discussed. Then different algorithms of global system for
mobile communications (GSM) and their work have been analysed using
qualitative method that we conducted our research which was the
research methodology we used for this study.GSM was one of the
first digital mobile phone systems to follow the analogue era.
Widely known problems with GSM's analogue counter parts were the
possibility of phone fraud through cloning phones and thus calling
in someone else's expense, and the possibility of someone
intercepting the phone call over the air and eavesdropping on the
discussion. The GSM system was supposed to correct these problems
by implementing strong authentication and encryption. A part of the
security in GSM comes from the fact that it is a digital system
employing speech coding and channel coding algorithms, GMSK
(Gaussian Minimum Shift Keying) modulation, slow frequency hopping
and time division multiple access (TDMA) timeslot architecture.
Finally the authentication and encryption algorithms for GSM were
tested using GSM network server and mobile station
