碩士 === 國立臺灣科技大學 === 資訊管理系 === 99 === With the development of information and communication technology, mobile devices can provide more diversified services, such as basic call and short message service (SMS for short), multimedia messaging service (MMS for short), recoding audio, camera and global positioning systems (GPS for short), etc. Therefore, more and more hackers or crackers attempt to develop malicious programs for mobile devices in order to invade, eavesdrop or control users personal mobile devices. It will harm personal privacy. However, most of mobile devices protection mechanisms focus on virus signature detecting and behavior blocking, and few ones provide privacy protection for smart mobile devices (such as contacts). This paper presents a SIM card encryption mechanism for privacy protection of mobile devices with subscriber identity modules. Further, the proposed scheme collocating with Scorgie’s malware detection method can achieve confidentiality and integrity of sensitive information. Furthermore, our proposed scheme meets the existing SIM card structure, and it is easy to implement the proposed scheme in the existing platform (such as android). We adopt the Windows mobile system for demonstrating the proof of concept.
