Secure data uploading scheme for a smart home system

Smart home systems have attracted the attention of users and intelligent device developers because of their convenience, efficiency and other characteristics. Security and privacy protection are major obstacles for the practical application of smart home systems. Home area networks (HANs) are an important part of smart home systems. A large number of researchers have devoted themselves to proposing secure transport strategies and key agreement schemes for HANs. However, there are still many problems with these schemes, such as the inability of the cloud to verify the integrity of uploaded data and the absolute right of home gateways to monitor and modify the data. In this paper, we propose a secure data uploading scheme, which ensures that the cloud validates the data integrity while avoiding malicious home gateways that monitor and modify the data. A security proof and simulations demonstrate that our protocol is secure and efficient.
