The Internet of Things (IoT) is gradually becoming mature and has already entered our daily life, which interconnects more machines and makes communication more convenient and more intelligent. Massive IoT devices produce innumerable data which need to be analyzed in joint cloud computation (JointCloud) with diversified services. However, due to the weak security of IoT devices, the existing JointCloud architecture hardly provides a secure trusted trade environment for users, which affects severely the application in the IoT network. In this article, we propose a hierarchical trust networking architecture based on permissioned blockchain to implement JointCloud (HTJC). The proposed Hyperledger fabric-based architecture has a better performance than those based on Ethereum in latency. By introducing the credit bonus-penalty strategy (CBPS), HTJC can solve the trust problem and provide users with a secure trusted trade environment. The availability of the proposed architecture is evaluated and compared to the existing models. The numerical results show that the HTJC can defend distributed denial-of-service (DDoS) attacks and provide users with a trusted and effective trade platform.

JointCloud的基于区块链的分层信任网络

物联网（IoT）逐渐成熟，已经进入我们的日常生活，它可以互连更多的机器，并使通信更加便捷和智能。大量的物联网设备会产生无数的数据，这些数据需要在具有多种服务的联合云计算（JointCloud）中进行分析。但是，由于物联网设备的安全性较弱，现有的JointCloud架构几乎无法为用户提供安全的可信交易环境，这严重影响了物联网网络中的应用。在本文中，我们提出了一种基于许可区块链的分层信任网络体系结构，以实现JointCloud（HTJC）。所提出的基于Hyperledger架构的架构在延迟方面比基于以太坊的架构具有更好的性能。通过引入信用红利罚金策略（CBPS），HTJC可以解决信任问题，并为用户提供安全的可信交易环境。评估所提出的体系结构的可用性并将其与现有模型进行比较。数值结果表明，HTJC可以防御分布式拒绝服务（DDoS）攻击，并为用户提供值得信赖且有效的交易平台。
