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
