Secure and Trusted Interoperability Scheme of Heterogeneous Blockchains Platform in IoT Networks
CHINA COMMUNICATIONS(2023)
Abstract
With the rapid development of the Internet of Things (IoT), there is an increasing need for interac-tion between different networks. In order to improve the level of interconnection, especially the interoper-ability of users/devices between different nodes is very important. In the IoT heterogeneous blockchain sce-nario, how to ensure the legitimacy of the chain and how to confirm the identity of cross-chain informa-tion users/devices become the key issues to be solved for blockchain interoperability. In this paper, we pro-pose a secure and trusted interoperability mechanism for IoT based on heterogeneous chains to improve the security of blockchain interoperability. In this mecha-nism, a primary sidechain architecture supporting au-thentication at both ends of the heterogeneous chain is designed. In addition, a distributed gateway archi-tecture is proposed for cross-chain authentication and protocol conversion. The security and performance analysis shows that our scheme is feasible and effec-tive in improving the security of cross-chain opera-tions in IoT.
