Despite the common usage, GSM has some security problems that seriously threaten information security. Lack of mutual authentication between base station and mobile terminal becomes prominent among security leaks of GSM and causes man-in-the middle attacks. In addition, by using fake base station attacks, attackers can get mobile terminal identity and eavesdropping, impersonation of mobile terminal and base station and other types of man-in-the-middle attacks can be taken place. Therefore, detection of fake base station attacks and warning mobile terminal users and GSM operators would be pretty important. In this work, fake base station attacks are analyzed. Then, fake base station attack detection algorithm is developed. Besides, by the help of proposed algorithm, feasibility of fake base station attack detection has been shown by simulation which is based on real GSM network values.
