Abstract:

The smart home has developed rapidly but its communication privacy problem has not been solved well. The anonymous communication model in the Internet environment cannot be directly used in smart home environment due to the limited computing power and bandwidth of smart home devices. The proposed method is aimed at the communication privacy problem of smart home when transmitting audio and video data. The method combines identity-based encryption and onion routing strategy, re-orders the file fragments before transmits them. Theoretical analysis and simulation prove that the proposed method reduces the computational power requirements, while still having good anonymity, security and anti-collusion attack capabilities.

Key words: identity based encryption, anonymous communication, smart home, audio and vide

摘要：

智能家居发展迅速但其通信隐私问题尚未得到较好解决，互联网环境下的匿名通信模型因智能家居设备受限的算力和带宽无法直接迁移到智能家居设备上。提出的方法针对智能家居在传输音视频数据时的通信隐私问题，融合基于身份的加密和洋葱路由策略，并对文件分片重新排序后按特定序列进行传输。理论分析和仿真证明提出的方法降低了算力需求，同时具有较好的匿名性、安全性和一定的抗合谋攻击能力。
