Collaborative Trust: A Novel Paradigm of Trusted Mobile Computing

With increasing complexity of modern-day mobile devices, security of these devices in presence of myriad attacks by an intelligent adversary is becoming a major issue. The vast majority of cell phones still remain unsecured from many existing and emerging security threats [1]. There are two major modes of threats for mobile wireless devices hardware and software. In the hardware field, many threats exist. Such threats include vulnerability to system malfunction, weakness of authentication procedures, and increasing threat of hardware Trojans [2-10]. In software, these threats include electronic eavesdropping, location tracking software, and malware [1] (software Trojan horses and viruses). In general, the security attacks in mobile devices – through either hardware or software or combination of both – primarily aim at either leaking personal information or causing system malfunction.
