为了物联网环境下数据传输和信息的安全,在对现有经典的物联网认证协议进行分析研究的基础上,提出了一种新的混合双向匿名认证协议。新协议是利用可信计算技术,采用基于双线性对的一次性公钥和散列函数相结合的方法。通过对安全性和效率的分析,新协议能够很好地满足物联网环境对存储和运算开销的要求,有效地保证终端与服务器端通信的隐私和数据安全,实现了双向认证和匿名认证。 相似文献

This paper describes the use of vision for navigation of mobile robots floating in 3D space. The problem addressed is that of automatic station keeping relative to some naturally textured environmental region. Due to the motion disturbances in the environment (currents), these tasks are important to keep the vehicle stabilized relative to an external reference frame. Assuming short range regions in the environment, vision can be used for local navigation, so that no global positioning methods are required. A planar environmental region is selected as a visual landmark and tracked throughout a monocular video sequence. For a camera moving in 3D space, the observed deformations of the tracked image region are according to planar projective transformations and reveal information about the robot relative position and orientation w.r.t. the landmark. This information is then used in a visual feedback loop so as to realize station keeping. Both the tracking system and the control design are discussed. Two robotic platforms are used for experimental validation, namely an indoor aerial blimp and a remote operated underwater vehicle. Results obtained from these experiments are described. 相似文献

The application of Internet-enabled devices in the real world for the development of Smart Cities, environmental monitoring, bus tracking, and parking requires scalability, extensibility, and integration of emerging resources to reach a suitable ecosystem for data acquisition and interaction with citizens. Internet of things needs to offer efficient support for global communications and access to services and information. It needs to enable homogeneous and seamless machine-to-machine communication for different solutions and applications. This work presents an homogeneous and suitable mechanism for global resource discovery, device access for deployed smart objects in different scenarios, and sensors and devices from end users (participative sensing). The integration of legacy and sensors already available from smart buildings and smart objects is presented. For this purpose, a resolution infrastructure called “digcovery” is defined for maximizing efficiency and sustainability of deployments. Digcovery architecture offers the framework to allow users to register/include their own sensors into a common infrastructure and access/discover the available resources through mobile digcovery. Mobile digcovery exploits the context-awareness, geo-location, and identification technologies available in mobile platforms such as smartphones to discover, interact, and access the resources through its ElasticSearch engine. 相似文献

With the advent of the information and related emerging technologies, such as RFID, small size sensors and sensor networks or, more generally, product embedded information devices (PEID), a new generation of products called smart or intelligent products is available in the market.Although various definitions of intelligent products have been proposed, we introduce a new definition of the notion of Intelligent Product inspired by what happens in nature with us as human beings and the way we develop intelligence and knowledge. We see an intelligent product as a product system which contains sensing, memory, data processing, reasoning and communication capabilities at four intelligence levels. This future generations of Intelligent Products will need new Product Data Technologies allowing the seamless interoperability of systems and exchange of not only Static but of Dynamic Product Data as well. Actual standards for PDT cover only lowest intelligence of today’s products. In this context, we try to shape the actual state and a possible future of the Product Data Technologies from a Closed-Loop Product Lifecycle Management (C-L PLM) perspective.Our approach is founded in recent findings of the FP6 IP 507100 project PROMISE and follow-up research work. Standards of the STEP family, covering the product lifecycle to a certain extend (PLCS) as well as MIMOSA and ISO 15926 are discussed together with more recent technologies for the management of ID and sensor data such as EPCglobal, OGC-SWE and relevant PROMISE propositions for standards.Finally, the first efforts towards ontology based semantic standards for product lifecycle management and associated knowledge management and sharing are presented and discussed. 相似文献
