Internet of Things (IoT) technology is poised to revolutionize a multitude of application sectors in the next few years. IoT refers to networks of autonomous and uniquely identifiable "smart" objects with embedded processors that have sensing, computing, communicating, and service discovery capabilities. IoT promises enormous application benefits in the areas of smart critical infrastructure such as power grids, water supply, nuclear plants, connected health, telecommunications, environment, agriculture and defence. Security, reliability, and trust stand out as three critical research areas in the design of IoT before the technology can be successfully deployed. While there is a broad corpus of independent solutions for addressing security, reliability and trust in IoT networks, an integrated approach has met with limited success due to many inherent challenges. Firstly, IoT devices mainly consist of small sensors with limited computational power, storage and bandwidth which makes the deployment of traditional security algorithms infeasible. Secondly, threat exposure of IoT systems increases due to their integration with different wireless technologies, each with its own vulnerability. Thirdly, nonuniform traffic, unpredictable topology changes, differing node densities, high degree of mobility, and high bit error rates dictate communication among IoT devices. Finally, there is little consensus among trust mechanisms for IoT.      The overarching goal of this research proposal is to build a unified architecture that integrates security, reliability and trust mechanisms in IoT networks. Towards the realization of this objective, this proposal will a) Investigate vulnerabilities, security threats, reliability and trust requirements specific to IoT; b) Perform analytics on IoT traffic data for modelling of attack and reliability vectors; c) Develop a context-aware framework for the design of a unified architecture for secure, reliable and trustworthy delivery of information over IoT networks; d) Experimentally validate the proposed architecture by developing and testing candidate applications on an IoT test bench. The novelty of the proposal is the design of an unified architecture that uses a context-aware framework consisting of three modules, namely, a cognitive module, an adaptive module, and an authentication module.       There is a major demand for the design of mechanisms for secure, reliable and trustworthy information transfer in IoT networks, especially since such networks are being increasingly deployed for business, healthcare, government and defence applications. This would be one of the first research proposals to integrate a set of lightweight mechanisms for security, reliability and trust in IoT. Thus, this research will not only train valuable HQP by giving them the unique combination of knowledge and expertise in this area but also has the potential to pave the way for the design of next generation wireless networks.

物联网（IoT）技术有望在未来几年内彻底改变众多应用领域。物联网是指由自主且可唯一识别的“智能”对象组成的网络，这些对象具有嵌入式处理器，具有传感、计算、通信和服务发现功能，在智能关键基础设施领域（如电网、供水、核电站、互联健康、电信、环境、农业和国防）有望带来巨大的应用效益。在物联网技术成功部署之前，安全性、可靠性和信任是物联网设计中的三个关键研究领域。虽然有广泛的独立解决方案可用于解决物联网网络的安全性，可靠性和信任问题，但由于许多固有的挑战，集成方法的成功有限。首先，物联网设备主要由计算能力、存储和带宽有限的小型传感器组成，这使得传统安全算法的部署不可行。其次，物联网系统的威胁暴露增加，因为它们与不同的无线技术集成，每种技术都有自己的漏洞。第三，不均匀的流量、不可预测的拓扑变化、不同的节点密度、高度的移动性和高误码率决定了物联网设备之间的通信。最后，物联网的信任机制之间几乎没有共识。 该研究提案的总体目标是建立一个统一的架构，在物联网网络中集成安全性，可靠性和信任机制。为实现这一目标，本提案将：a）调查物联网特有的漏洞、安全威胁、可靠性和信任要求; B）对物联网流量数据进行分析，以便对攻击和可靠性向量进行建模; c）开发一个上下文感知框架，用于设计统一架构，以便通过物联网网络安全、可靠和值得信赖地交付信息; d）通过在物联网测试台上开发和测试候选应用程序来实验验证所提出的架构。该提案的新奇在于设计了一个统一的架构，该架构使用由三个模块组成的上下文感知框架，即认知模块，自适应模块和认证模块。 人们对物联网网络中安全、可靠和值得信赖的信息传输机制的设计有很大的需求，特别是因为这些网络越来越多地被部署用于商业、医疗保健、政府和国防应用。这将是第一个整合一套轻量级机制以实现物联网安全性、可靠性和信任的研究提案之一。因此，这项研究不仅将培训有价值的HQP，让他们在这一领域的知识和专业知识的独特组合，但也有可能为下一代无线网络的设计铺平道路。
