The design of AES-DN embedded cryptographic processor for the RFID/USN environment

Abstract

With the widespread use of embedded system based ubiquitous system, there is a rapid increase of the RFID/USN environment.. However, the security for the RFID/USN environment has been far behind the speed of rising security threats. In this regard, this study proposed a AES-DN embedded encryption system for RFID/USN. Compared to the existing AES, the proposed AES-DN processes 120% faster and is equipped with the DN-R method reducing node loads, which is most important for the RFID/USN environment. Therefore AES-DN is considered to be an ideal algorithm to address limited resources of the RFID/USN environment. © 2011 Springer-Verlag.
