The active RFID 125Khz technique and authentication in micro location

Abstract

In this paper, we provide an overview of active RFID (Radio Frequency Identification) technique at low frequency band LF 125kHz for identification and authentication in micro location application. Section 1 describes about working principle of RFID technology, the advantages and disadvantages of both passive and active RFID techniques are also taken into account. Following sections, the problem of identification and authentication for vehicle’s owner is considered. The current solutions for this problem are being used, nowadays. Section 3, we propose an active RFID system with OTP and data encryption scheme that encrypts OTP to protect data, avoid hacking and anti-counterfeit authentication. The detail of hardware architecture and software algorithm are described in section 4. In section 5, the experimental results emphasize the advantage of active RFID system in reading distance. It also provides an estimation of coin battery life-time about 3,5 years in a system with low power RF receiver chip AS3933. With benefits of proposed solution, it can be applied for UWB (Ultra Wideband) devices which going to be the main topic of real time location applications in very near future.
