A lightweight multi-party authentication in insecure reader-server channel in RFID-based IoT

Abstract: The rapid proliferation of Radio Frequency Identification (RFID) tags in the past decade has made tremendous impact on our daily lives. As part of Internet of Things (IoT), RFID technology ensures an efficient, secure and reliable system to identify tagged objects in supply chain environment such as manufacturing, automotive and healthcare. Several lightweight authentication solutions have been proposed to satisfy optimal security and privacy features of RFID communication. Hopper-Blum (HB) family of protocols that rely on the hard problem of Learning Parity with Noise (LPN) is a series of lightweight authentication protocol used to identify RFID tags. Our study shows that recent RFID authentication protocols from HB family that mostly focus on two party authentication such as tag-reader authentication, in general, cannot be applied directly to a three party authentication such as tag-reader-server authentication. In contrast to typical RFID authentication system, we consider the channel between the reader and back-end server insecure. We focus HB protocol and its variants and propose a modified protocol where the entire system is authenticated under LPN-based scheme.

Political Theory by Other Means: An Introduction

Abstract: The articles in this issue explore political theory by means other than is common in the discipline. More typical activities involve the reconstruction of the thought of our predecessors; clarification of the languages and concepts we alternately take for granted and debate as citizens and scholars; and the evaluation of the performance and justification of public policies, political institutions and their leaders in light of

Productivity Growth in Canadian and U.S. Regulated Industries

Abstract: This paper compares the productivity growth of a set of Canadian and U.S. regulated industries. Using data from Statistics Canada’s KLEMS database and the U.S. Bureau of Economic Analysis, the paper examines productivity growth in transportation services (which includes air and rail), broadcasting and telecommunications, and financial services (which includes financial intermediation and insurance), over the period from 1977 to 2003. The majority of these provide the foundational networks on which other industries rely. These sectors were quite heavily regulated in Canada at the beginning of the period of study (1977), experienced partial deregulation during the period and still faced various types of regulation at the end (2003). Deregulation also occurred in the United States, but regulation has generally been less restrictive there over most of the period.The evidence shows that many of the Canadian industries that underwent deregulation experienced faster labour productivity growth and multifactor productivity growth than did the aggregate Canadian business sector and had similar or higher productivity growth than did their counterparts in the United States over the 1977-to-2003 period. Those industries include rail transportation, broadcasting and telecommunications, financial intermediation and insurance carriers. The airline industry had slower productivity growth in Canada than in the United States over the 1977 to 2003 period.

Looking Back: State Fragility and a Generation of Conflict

Abstract: Having endured a generation of devastating conflict under Saddam Hussein and in the chaos following his overthrow in 2003, Iraq may now be gearing up for another generation of violence. The potential consequences for Iraq, the region, and the world are incalculable. What drives this conflict? Where do the sources of this ongoing instability lie? What options do Iraqis have to bring stability to their country? What levers does the international community have to help them? These are the questions this volume seeks to address.
