Lightweight cryptography for low cost RFID

Abstract

Security and privacy concerns as well as the need for security services to enable the development of novel applications using low cost RFID have been illustrated in previous Chapters, and in particular various proposals made to address issues regarding information security and end-user privacy have been discussed in Chapter 6. However, some of these ideas are not practicable for secure low-cost RFID on account of their demand for circuit size and operational power while others fail to meet various security and privacy objectives adequately. The solutions presented have not considered: aspects unique to low cost RFID, system performance requirements and consequences and practicability of implementation in a system wide context. This chapter aims to propose a number of practicable solutions based on lightweight cryptography that address the security objectives and privacy goals outlined in Chapter 6 and are based on the low cost RFID framework outlined therein. The proposed solutions are then evaluated for their merits using the evaluation framework developed in Chapter 8. © 2008 Springer-Verlag Berlin Heidelberg.
