摘要:

物联网(IoT)的日益普及通过将越来越多有吸引力的攻击目标(即嵌入式设备)连接到互联网来扩大攻击面。保护这些设备的一个关键组件是软件完整性检查,通常通过远程证明(RA)实现。RA被实现为交互式协议,由此可信方(验证器)验证潜在受损的远程设备(证明器)的软件完整性。在绝大多数物联网应用中,智能设备以集群方式运行,因此需要高效的集群认证方案。在本文中,我们提出了WISE,第一个智能群认证协议,旨在尽量减少通信开销,同时保持足够的安全性。WISE依赖于一种资源高效的智能广播身份验证方案,其中设备被组织在细粒度的多集群中,并且在需要时,最有可能受到攻击的设备会被证明。考虑到群中每个设备的证明历史和不同特征(和约束),智能地选择候选设备。我们表明,WISE非常适合资源受限的嵌入式设备,在异构物联网网络中具有高效率和可扩展性,并提供可调节的安全级别。

英文摘要:

The growing pervasiveness of Internet of Things (IoT) expands the attack surface by connecting more and more attractive attack targets, i.e. embedded devices, to the Internet. One key component in securing these devices is software integrity checking, which typically attained with Remote Attestation (RA). RA is realized as an interactive protocol, whereby a trusted party, verifier, verifies the software integrity of a potentially compromised remote device, prover. In the vast majority of IoT applications, smart devices operate in swarms, thus triggering the need for efficient swarm attestation schemes. In this paper, we present WISE, the first intelligent swarm attestation protocol that aims to minimize the communication overhead while preserving an adequate level of security. WISE depends on a resource-efficient smart broadcast authentication scheme where devices are organized in fine-grained multi-clusters, and whenever needed, the most likely compromised devices are attested. The candidate devices are selected intelligently taking into account the attestation history and the diverse characteristics (and constraints) of each device in the swarm. We show that WISE is very suitable for resource-constrained embedded devices, highly efficient and scalable in heterogenous IoT networks, and offers an adjustable level of security.
