The fast growth of mobile networks has greatly enriched our life by disseminatinginformation and providing communications at anytime and anywhere. However, at thesame time, when people gather and exchange useful information, they also receiveunwanted data and contents, such as spam and unsolicited commercial advertisements.SMS (Short Message Service) spam is one typical example of unwanted contents, whichhas caused a serious problem to mobile users by intruding their devices, occupyingdevice memories and irritating the users. More critically, some of these fraudulentmessages deceive users and cause them incalculable loss. SMS spam control hasbecome a crucial issue that impacts the future success of mobile networks. A number ofresearches have been conducted to control unwanted contents or traffic via trust andreputation mechanisms, but an effective solution is particularly important for SMS spamcontrol. In this paper, we present the design and implementation of an SMS spamcontrol system named TruSMS based on trust management. It can control SMS spamfrom its source to destinations according to trust evaluation by analyzing spam detectionbehaviors and SMS traffic data. We evaluate TruSMS performance under a variety ofintrusions and attacks with a prototype system implementation. The result shows thatTruSMS is effective with regard to accuracy, efficiency and robustness, which impliesits trustworthiness.
