摘要: 在物联网(IoT)技术领域,通过云计算与边缘计算的协同,构建云边协同IoT可以显著减少核心网络中的流量负载以及IoT业务的服务时延。然而,传统密码学技术无法抗衡量子计算机的攻击,IoT的数据传输安全倍受威胁。量子密钥分发技术的应用,能够增强云边协同IoT安全能力。为了提升云边协同IoT的安全,基于量子密钥分发设计了一种云边协同光量子IoT安全体系架构,以及内嵌量子密钥服务的IoT网关模型与工作流程。同时,在该架构下,为了承载IoT业务并为其分发密钥,提出了面向业务密钥需求的节点密钥供应能力属性,以及节点密钥供应能力感知的密钥资源分配方法。仿真实验结果在密钥供应成功率、业务平均密钥消耗量和网络密钥利用率方面验证了所提方法的性能。与对比方法相比,所提方法能够显著提升密钥供应成功率。

Abstract: In the field of Internet of things (IoT) technology, by collaborating the cloud computing and the edge computing, building the cloud-edge collaboration based IoT can significantly reduce the traffic load in the core network and the service latency of IoT services. However, traditional cryptography technology cannot resist the attacks from quantum computers, which challenges the data transmission security of IoT. To tackle this challenge, quantum key distribution (QKD) can be applied to enhance the security of the cloud-edge collaboration based IoT. A security architecture of cloud-edge collaboration is designed that based optical-quantum IoT with QKD, an IoT gateway model and a workflow with quantum key service embedded. Additionally, in the architecture, to carry the IoT services and distribute keys for them, the key supply capability attribute of nodes oriented to the key demands of services and the key-supply-capability-aware resource allocation method is proposed. The performance of the proposed method in terms of key distribution success ratio, average key consumption of services and key resource utilization ratio is verified by simulation. The simulation results show that compared with the baseline, the proposed method can significantly improve the key distribution success ratio.

Key words: cloud-edge collaboration, optical-quantum Internet of things, quantum key distribution, resource allocation
