用于工业物联网的轻量级可搜索加密协议

Lightweight searchable encryption protocol for industrial Internet of Things

工业物联网存在身份认证不充分、网络拓扑不动态等问题,导致数据保密出现漏洞。基于属性的加密方案被视为确保数据传输安全和加密物联网数据细粒度共享的一种解决方案。因此,设计适合物联网应用的轻量级、高效数据共享和搜索方案非常重要。文章提出了一种用于工业物联网的轻量级可搜索加密协议。通过为数据用户提供多关键字搜索,该协议可以显著降低物联网设备的计算成本。同时,文章将LSABE方案扩展到多授权场景,以便在分布式物联网环境中有效生成和管理公钥/密钥。实验结果表明,该方案可以显著保持计算效率并节省物联网设备的计算成本。

The industrial Internet of Things has problems such as insufficient identity authentication and non dynamic network topology,leading to vulnerabilities in data confidentiality.Attribute based encryption schemes are considered a solution to ensure secure data transmission and fine-grained sharing of encrypted IoT data.Therefore,designing lightweight and efficient data sharing and search solutions suitable for IoT applications is crucial.The article proposes a lightweight searchable encryption protocol for industrial Internet of Things.By providing multi-keyword search for data users,this protocol can significantly reduce the computational cost of IoT devices.Meanwhile,the article extends the LSABE scheme to multi-authorization scenarios,in order to effectively generate and manage public keys/keys in a distributed IoT environment.The experimental results show that this scheme can significantly maintain computational efficiency and save the computational cost of IoT devices.
