Radio frequency identification (RFID) tag delegation enables a centralized back-end server to delegate the right to identify
and authenticate a tag to specified readers. This should be used to mitigate the computational load on the server side and
also to solve the issues in terms of latency and dependency on network connectivity. In this study, we describe a basic RFID
delegation architecture and then under this model, we investigate the security of an RFID delegation protocol: Song Mitchell
delegation (SMD), which is recently proposed by Song and Mitchell. We point out security flaws that have gone unnoticed in
the design and present two attacks namely, a tag impersonation attack and a desynchronization attack against it. We also discover
a subtle flaw by which a delegated entity can still keep its delegation rights after the expire of them—this infringes security
policy of the scheme. More precisely, we show that the protocol will be still vulnerable to previously mentioned attacks,
even if the back-end server ends the delegation right of a delegated reader and update the secrets of the delegated tags.
To counteract such flaws, we improve the SMD protocol with a stateful variant so that it provides the claimed security properties. 相似文献

The Internet of Things (IoT) concept is being widely presented as the next revolution toward massively distributed information,
where any real-world object can automatically participate in the Internet and thus be globally discovered and queried. Despite
the consensus on the great potential of the concept and the significant progress in a number of enabling technologies, there
is a general lack of an integrated vision on how to realize it. This paper examines the technologies that will be fundamental
for realizing the IoT and proposes an architecture that integrates them into a single platform. The architecture introduces
the use of the Smart Object framework to encapsulate radio-frequency identification (RFID), sensor technologies, embedded
object logic, object ad-hoc networking, and Internet-based information infrastructure. We evaluate the architecture against
a number of energy-based performance measures, and also show that it outperforms existing industry standards in metrics such
as network throughput, delivery ratio, or routing distance. Finally, we demonstrate the feasibility and flexibility of the
architecture by detailing an implementation using Wireless Sensor Networks and Web Services, and describe a prototype for
the real-time monitoring of goods flowing through a supply chain. 相似文献

We study feedback tracking problems for the planar vertical takeoff and landing (PVTOL) aircraft dynamics, which is a benchmark model in aerospace engineering. We provide a survey of the literature on the model. Then we construct new feedback stabilizers for the PVTOL tracking dynamics. The novelty of our work is in the boundedness of our feedback controllers and their applicability to cases where the velocity measurements may not be available, coupled with the uniform global asymptotic stability and uniform local exponential stability of the closed‐loop tracking dynamics and the input‐to‐state stable performance of the closed‐loop tracking dynamics with respect to actuator errors. Our proofs are based on a new bounded backstepping result. We illustrate our work in a tracking problem along a circle. Copyright © 2011 John Wiley & Sons, Ltd. 相似文献

The least-squares linear estimation problem (including prediction, filtering and fixed-point smoothing) from measurements transmitted by different sensors subject to random packet dropouts is addressed. For each sensor, a different Bernoulli sequence is used to model the packet dropout process. Under the assumption that the signal evolution model is unknown, recursive estimation algorithms are derived by an innovation approach, requiring only information about the covariances of the processes involved in the observation equation, as well as the knowledge of the dropout probabilities at each sensor. 相似文献
