This paper surveys recent technical researches on the problems of privacy and security for various applications in radio frequency identification (RFID). Most RFID system try to design a high level security, but not all of the RFID applications need it. The cost will increase if the privacy and security simultaneously improve, thus, how to balance the two(More)
S ecurity and privacy concerns present serious challenges in RFID systems. Traditional encryption methods are insufficient in such systems because RFID tags have limited processing and memory capabilities. Each tag has its own ID and is installed in an open environment to help retailers identify and locate trade items, logistical units, and assets. When a(More)
Radio Frequency Identification (RFID) system can be read by radio wave within several metres without having direct contact. Many research focus on improving security and privacy problem. Recently, Rizomiliotis et al. point out that Song-Mitchell protocol is vulnerable to the denial of service attack, since the attacker can easily modify the data to make the(More)
In the past researches, most of the authentication protocols were designed in an effort to solve the RFID security and privacy problem regarding the encrypted communication between the database and readers, and readers and tags. Based on the proposal of mobile agent device for RFID privacy protection (MARP), some security problems have been exposed. Later(More)
Grid computing has contributed to advances in computational and communication technologies, which has made economically feasible the conglomeration of multiple clusters of heterogeneous networked resources and services that, in turn, has lead to the development of large-scale distributed systems. However, available resources may be shortage. We propose a(More)
