Abstract

In order to solve the security issues of each trusted application domain, to ensure cross-domain sharing of private data, this paper proposed a cross-domain sharing model of private data based on the master-slave chain. Firstly, it presented a master-slave chain, and constructed a system architecture based on the master-slave chain. Then it designed a cross-domain access mechanism based on smart contracts, and put forward further the cross-domain secure sharing scheme for private data. Finally, it carried out an experimental analysis for stability, throughput and storage overhead for the proposed model. The experimental results show that, compared with the latest single-chain cross-domain models, the throughput has been improved by about 270 TPS, and the average CPU load and average memory overhead of the node are reduced by 24% and 64% in the proposed model respectively. Compared with the existing multi-chain cross-domain models, the average CPU load and average memory overhead of the node has dropped by 15% and 20%, respectively. The proposed model has provided an effective method for cross-domain secure access and sharing for the Internet of Things privacy data.
