物联网代表了无处不在的计算和通信技术的融合，以及在现实世界中驱动的新兴用途。无处不在的计算系统不再简单地以数字方式感知和响应，现在它们与世界进行物理交互，最终变得具体化和自主化。与此同时，游戏正在从隐私的游戏转变为用户安全的游戏，用户(以及监管机构、政府和其他利益相关者)肯定会关心用户。同样，行业需要意识到，这种转变也改变了公司运营所需的法律基础，从完全不同且往往执法不力的隐私法，转变为产品责任。目前被广泛采用的云服务支撑物联网设备的方法已经引发了重大的隐私问题。重要的是，在一个充满动力的未来，不受限制的通信在正常运营中牵涉到过多的异类在线服务，也带来了弹性挑战。我们必须确保执行系统的完整性，这将需要更大的地方自治权，同时增加对用户的责任。这个问题适用于许多领域：工业控制、自动驾驶汽车、智能城市和建筑，包括家庭的亲密和共享环境。这项研究试图在家庭环境中解决这一挑战，在家庭环境中，网络基础设施保护最少，连接的设备与它们所承载的流量之间几乎没有隔离。从普通公民的角度来看，研究界对家庭网络安全及其可接受性和可用性的关注很少。这项研究也深深植根于实用主义，并认识到物联网附带的“真实世界、实时”条件：--目前为物联网系统定义的网络安全解决方案不会处理遗留问题，永远不会实现100%的采用；-现有企业限制其提供软件和安全更新的时间段(即使它们仍在营业)；-网络安全是一场军备竞赛，未来威胁将继续出现；-公众永远不会成为网络安全专家。

The IoT represents a convergence of ubiquitous computing and communication technologies, with emerging uses that actuate in the real world. No longer do ubiquitous computing systems simply sense and respond digitally, now they physically interact with the world, ultimately becoming embodied and autonomous. At the same time, the game is changing from one of privacy, where it is often (contestably) cited that "users don't care", to one of user safety, where users (along with regulators, governments, and other stakeholders) certainly do care. Likewise, industry needs to become aware that this shift also changes the legal basis under which companies need to operate, from one of disparate and often weakly enforced privacy laws, to one of product liability. The current widely adopted approach in which cloud services underpin IoT devices has already raised major privacy issues. Importantly in an actuated future, untrammelled communications implicating a plethora of heterogeneous online services in their normal operation also brings with it resilience challenges. We must ensure the integrity of actuating systems, which will require greater local autonomy alongside increased situated accountability to users. This problem applies in many areas: industrial control, autonomous vehicles, and smart cities and buildings, including the intimate and shared context of the home.This research seeks to address the challenge in the context of the home, where the network infrastructure protection is minimal, providing little or no isolation between attached devices and the traffic they carry. Scant attention has been paid by the research community to home network security, and its acceptability and usability, from the viewpoint of ordinary citizens.This research is also deeply rooted in pragmatism and recognises the 'real world, real time' conditions that attach to the IoT:- that the cyber security solutions currently being defined for IoT systems will not deal with legacy issues and will never achieve 100% adoption; - that extant businesses limit the period of time for which they will provide software and security updates (if they even remain in business); - that cyber security is an arms race and threats will continue to emerge in future; - and that the public will never become network security experts.
