The Internet of Multimedia Things (IoMT) has become the backbone of innumerable multimedia applications in various fields. The wide application of IoMT not only makes our life convenient but also brings challenges to service discovery. Service discovery aims to leverage location information and trust evidence scattered in a variety of multimedia applications to find trusted IoMT devices that can provide specific service in target areas. However, the eavesdropping and tampering to these sensitive IoMT data during the trust propagation process invalidate the service discovery process. To address these challenges, we propose Secure Service Discovery (SSD) for IoMT using cross-blockchain-enabled fog computing. To resist the tampering and eavesdropping during the trust propagation process, a scalable cross-blockchain structure consisting of multiple parallel blockchains is first proposed based on fog, in which different parallel blockchains can be orchestrated to propagate encrypted location information and trust evidence of different applications. Moreover, to enable a cross-blockchain structure to leverage encrypted location information and trust evidence to find trusted IoMT devices in preset areas, a novel privacy-preserving range query is proposed to query and aggregate trust evidence. Security analysis and simulations are carried out to demonstrate the effectiveness and security of the proposed SSD.

基于雾的多媒体物联网安全服务发现

多媒体物联网(IoMT)已成为各个领域无数多媒体应用的支柱。IoMT 的广泛应用不仅给我们的生活带来了便利,也给服务发现带来了挑战。服务发现旨在利用分散在各种多媒体应用程序中的位置信息和信任证据来寻找可以在目标区域提供特定服务的可信 IoMT 设备。然而,在信任传播过程中窃听和篡改这些敏感的 IoMT 数据会使服务发现过程失效。为了应对这些挑战,我们建议使用支持跨区块链的雾计算为 IoMT 提供安全服务发现 (SSD)。为了抵御信任传播过程中的篡改和窃听,首次基于雾提出了一种由多个并行区块链组成的可扩展跨区块链结构,其中可以编排不同的并行区块链来传播不同应用程序的加密位置信息和信任证据。此外,为了使跨区块链结构能够利用加密的位置信息和信任证据来找到预设区域内的可信物联网设备,提出了一种新颖的隐私保护范围查询来查询和聚合信任证据。进行安全分析和模拟以证明所提出的 SSD 的有效性和安全性。为了使跨区块链结构能够利用加密的位置信息和信任证据在预设区域中找到受信任的 IoMT 设备,提出了一种新颖的隐私保护范围查询来查询和聚合信任证据。进行安全分析和模拟以证明所提出的 SSD 的有效性和安全性。为了使跨区块链结构能够利用加密的位置信息和信任证据在预设区域中找到受信任的 IoMT 设备,提出了一种新颖的隐私保护范围查询来查询和聚合信任证据。进行安全分析和模拟以证明所提出的 SSD 的有效性和安全性。
