摘　　要：随着区块链的快速发展与广泛应用,如何打通各区块链系统,实现数据资产价值互通,是近年来的研究热点。资产转移是跨链领域中的重要应用之一,因此针对跨链资产转移的身份与资产数据隐私保护需要,构建了一个基于同态加密的跨链资产转移隐私保护技术架构。综合运用同态加密、数字签名、零知识证明等相关技术,保障跨链资产的安全转移,为用户提供更为隐私安全的数字资产交易环境。此外,通过跨链网关与区块链的可溯源性,确保交易的可审计性,为整个系统增添了额外的安全层级,保障用户跨链资产转移的安全性与隐私性。With the rapid development and widespread application of blockchain,how to cross various blockchain systems and achieve the value interoperability of data assets is a hot research topic in recent years.Asset transfer is one of the important applications in the cross-chain field.In view of the identity and asset data privacy protection needs of cross-chain asset transfer,a cross-chain asset transfer privacy protection scheme based on homomorphic encryption is constructed.It comprehensively uses homomorphic encryption,digital signatures,zero-knowledge proof and other related technologies to ensure the safe transfer of cross-chain assets,providing users with a more private and secure digital asset trading environment.In addition,the traceability of cross-chain gateway and blockchain ensures the auditability of the transactions,adding an extra layer of security to the entire system and ensuring the security and privacy of users’cross-chain asset transfers.
