A lightweight mutual authentication protocol for RFID networks

Radio frequency identification (RFID) technology is expected to become an important and ubiquitous infrastructure technology of supply chain processes and customer service. The low-cost tag, or so-called passive tag, will be likely the factor for widespread adoption of the technology. It must be noticed that the deployment of such tags may create new threats to user privacy due to the powerful tracking capability of the tags. As a result, some sort of security issues must be imposed on the passive tags for addressing the privacy problem. However, providing security in such tags is a challenging task because they are highly resource constrained and cannot support strong cryptography. This paper provides both discussion on the requirements and restrictions of security implementation of a RFID system. It also examines the features and issues pertinent to several existing RFID security solution. Finally, this paper suggests the use of our proposed lightweight security protocol based on Ohkubos scheme, which protects user privacy using a hash chain mechanism and also provides an analysis of the protocol

SOA-Trust: Towards Developing Trustworthy RFID Enabled Intelligent Service Solutions

In this paper, we will introduce the concept of trustworthy Service Oriented Architecture (SOA) for enabling intelligent and yet trustworthy pervasive service solutions. In pervasive services enabled e- logistics, trustworthiness establishment is usually under resource constraints, presenting challenges for mutual trust establishment as well as system dependability. In this paper we will present a trustworthy service framework. A demonstration of this framework is through realizing a smart marketing solution in a supermarket.

Experimental Analysis of an RFID Security Protocol

Radio frequency identification (RFID) technology is expected to become a critical and ubiquitous infrastructure technology of logistics and supply chain management (SCM) related processes and services. Low-cost has been the key to RFID adoption in many logistics/SCM applications. However, the deployment of such tags may create new threats to user privacy due to the powerful track and trace capabilities of the tags, in addition to tag/reader manufacturing challenges. As a result, some security mechanisms must be imposed on the RFID tags for addressing the privacy problems. This paper provides detailed discussion on our proposal of a lightweight RFID security protocol. It examines the features and issues through experimental analysis pertinent to efficiency and scalability to meet the requirements of the proposed security protocol in metering and payment e-commerce applications

Contextual collaboration: platform and applications

Contextual collaboration refers to people-to-people collaboration from within IT-enabled business operations. We have designed and implemented a middleware platform for enabling contextual collaboration, and built collaborative applications on top of the platform. The platform embodies three main themes: on-demand, adaptive, and integrated. It is on-demand in that it allows collaboration data and services to be accessed from within business applications as the business need arises. It is adaptive in that it brings the right set of collaboration elements to the user, in a manner sensitive to business context. It integrates collaboration elements across multiple sources, multiple modalities, and multiple vendor technologies. In addition, it integrates structured collaborative activities with ad hoc peer collaboration tools, and with the business processes at large. To validate and leverage the contextual collaboration platform, we have developed an eclipse-based collaborative development environment and a browser that enables collaborative Web applications. Our contextual collaboration platform and applications promise to yield a more productive and more satisfying business practice.

A Web serivces community model for services fulfillment [serivces read services]

In this paper we introduce a Web service promotion model - Web services community. This service community supports three types of IT resource management networks - participant network, service network, and resource network. We then analyze a quality of service model for a set-vice request from multi-perspectives for the purpose of evaluating the service fulfillment. Finally an optimization approach based on the three types of networks is developed for optimizing the service fulfillment in this service community.
