TAILIEUCHUNG - Báo cáo " Mutual authentication between RFID tag and reader using Elliptic curve cryptography "

This paper presents an approach related to authenticate mutually a RFID (Radio Frequency Identification) tag from a RFID reader by using the cryptography based on Elliptic curve. Our proposal mutual authentication lies on the Elliptic curve discrete logarithm problem, which is considered the core in order to fight against all of attacks like replay attack, forgery attack and man-in-the-middle attack. Scientifically, we prove not only the accuracy and the security of our approach, but also its performance in the mutual authentication between a RFID tag and a reader. . | VNU Journal of Science Natural Sciences and Technology 24 2008 36-43 Mutual authentication between RFID tag and reader using Elliptic curve cryptography Nguyen Ngoc Hoa Dang Thu Hien Tran Thuy Trang College of Technology Vietnam National University Hanoi 144 Xuan Thuy Ha Noi Vietnam Received 15 November 2007 Abstract.

The obtained result of our approach is considered a good step toward the enhancement of safety security of biometric passport. Keywords RFID elliptic curve cryptography mutual authentication. 1. Introduction Actually RFID stands for radio-frequency identification is considered as a novel technology dedicated to system for automated identification of both objects and people. In reality human beings are very skilful at identifying objects under a variety of circumstances. For example a bleary-eyed person can easily pick out a pen on a desk while working. However computer vision performs such tasks poorly. Thus RFID may be viewed as a means of explicitly labelling objects people in order to facilitate their perception by computing devices 1 .

E-mail An RFID device - frequently just called an RFID tag - is a small microchip designed for twice objectives wireless data transmission and identification by using an attached antenna in a package resembling an ordinary adhesive sticker. The microchip itself can be as small as a grain of sand some
