摘要

物联网中基于网络的部署越来越依赖于云控制的单个网络联盟来配置、授权和管理跨网络边界的设备。虽然这种方法可以方便和可靠地互连网络,但它引起了严重的安全和安全问题。这些问题的范围从好奇的云提供商访问机密数据到恶意的云提供商能够物理控制安全关键设备。为了克服这些问题,我们提出了D-CAM,它可以在基于云的物联网中实现跨网络边界的安全和分布式配置、授权和管理。使用D-CAM,我们将云限制为控制消息的高可用性和可扩展存储。因此,我们实现了跨网络边界的可靠网络控制和强大的安全保障。我们的评估证实,D-CAM只增加了适度的开销,并且可以扩展到大型网络。

Distributed Configuration, Authorization and Management in the Cloud-Based Internet of Things
Network-based deployments within the Internet of Things increasingly rely on the cloud-controlled federation of individual networks to configure, authorize, and manage devices across network borders. While this approach allows the convenient and reliable interconnection of networks, it raises severe security and safety concerns. These concerns range from a curious cloud provider accessing confidential data to a malicious cloud provider being able to physically control safety-critical devices. To overcome these concerns, we present D-CAM, which enables secure and distributed configuration, authorization, and management across network borders in the cloud-based Internet of Things. With D-CAM, we constrain the cloud to act as highly available and scalable storage for control messages. Consequently, we achieve reliable network control across network borders and strong security guarantees. Our evaluation confirms that D-CAM adds only a modest overhead and can scale to large networks.
