Internet of things (IoT) plays a key role in enabling smart sustainable cities. Pervasive computing over the IoT platform makes life more convenient by embedding sensors based on context-aware computing devices in the physical environment for the ubiquitous availability of computing resources. The sensors gather contextual information from the physical world and transmit it to receivers as per requirements or in case of environmental changes, such as temperature and humidity. However, the combination of dynamic operation and the need to handle sensitive and private data make the pervasive computing environment and IoT devices vulnerable to numerous attacks. Smart environments require a maximum level of safety assurance, such as trusted context producers and customers, which should protect sensitive information from exposure or monitoring. This paper discusses the major cyber threats in smart environments and proposes a novel lightweight security framework that authenticates and maintains the context providers and receivers. The cloud environment is adopted for user authentication at the user layer to implement access control and role assignment. Finally, the proposed security framework is implemented in the IBM cloud platform with six devices to evaluate its efficiency, sustainability, and secure communication.

面向上下文的轻量级网络安全框架,适用于普适计算环境

物联网(IoT)在实现智能可持续城市方面发挥着关键作用。物联网平台上的普适计算通过在物理环境中嵌入基于上下文感知的计算设备的传感器来实现无处不在的计算资源,从而使生活更加便利。传感器从物理世界中收集上下文信息,并根据要求或在环境变化(例如温度和湿度)的情况下将其传输到接收器。但是,动态操作与处理敏感和私有数据的需求相结合,使得普及的计算环境和IoT设备易受多种攻击。智能环境需要最高级别的安全保证,例如受信任的上下文生产者和客户,应保护敏感信息免遭暴露或监视。本文讨论了智能环境中的主要网络威胁,并提出了一种新颖的轻量级安全框架,该框架对身份提供者和接收者进行身份验证和维护。在用户层采用云环境进行用户认证,以实现访问控制和角色分配。最后,所提出的安全框架在IBM云平台中用六种设备实施,以评估其效率,可持续性和安全通信。
