A Study of Security Vulnerabilities in Mobile environment

Abstract

Now day's application had focus more on the security and Radio Frequency Identification (RFID) had become one of the major technologies that become important for security. RFID devices are going to be ubiquitous applications that are used in different areas especially in the business because it simplifies many business transactions. However, security and privacy issues and risks are introduced by pervasiveness of RFID systems. In RFID systems, communication between tag and reader usually takes place via wireless communication. As the nature of radio frequency signal, it can go everywhere and everyone can receive this signal, which is an insecure channel. The computational resources in RFID tag are constrained and it is a big limitation that forces researcher to apply different mitigations compared to common security solutions. At the first part of this research, RFID architecture is introduced briefly. In this paper, the researcher explains existing security challenges in RFID networks then the effects of these threats on security and privacy of RFID are discussed. After analyzing security challenges of RFID networks, different countermeasures that are proposed by other researchers are discussed. At the end of this paper, future security challenges are discussed.
