Abstract: To enhance the security and privacy of cross-chain data exchange, a data exchange and security management protocol based on blockchain is proposed. It utilises a cross-chain channel matching model, employing communication protocols between relay chains and licensed blockchains. A communication protocol based on payment script hashes is designed. Experimental verification demonstrated that the peer matched consensus mechanism of this model has advantages in energy efficiency, decentralisation, and scalability. The proposed communication protocol completed calculations within 3 ms with 10 participants, using a maximum communication overhead of 6 KB. The cross-chain data protection protocol reduced the average exchange time by 9.08% at different problem nodes, achieving a 79% protection effect. Results indicate that the proposed model achieves data information protection during cross-chain exchange, while the communication exchange protocol enhances information security through decentralisation. The data security management protocol reinforces privacy and security in cross-chain exchange processes.
