摘　　要：在数字经济时代,异地灾备系统对保障企业数据安全和业务连续性发挥着关键作用。针对异地灾备过程中数据篡改和传输安全问题,提出一种基于区块链与双重加密的安全传输机制。通过构建分布式防篡改模型,实现数据完整性验证;采用非对称加密算法结合动态密钥分配方案,确保数据传输安全。实验结果表明,该方案在数据传输效率、存储成本和安全性方面表现良好,能够有效防御中间人攻击和重放攻击,数据完整性验证准确率达97.8%,传输时延增加约12%。该研究为异地灾备系统的数据安全保护提供了新思路。In the digital economy era,remote disaster recovery systems play a crucial role in ensuring enterprise data security and business continuity.A secure transmission mechanism based on blockchain and dual encryption is proposed to address data tampering and transmission security issues during remote disaster recovery.By constructing a distributed tamper proof model,data integrity verification can be achieved;Adopting asymmetric encryption algorithm combined with dynamic key distribution scheme to ensure data transmission security.The experimental results show that this scheme performs well in terms of data transmission efficiency,storage cost,and security,and can effectively defend against man in the middle attacks and replay attacks.The accuracy of data integrity verification reaches 97.8%,and the transmission delay increases by about 12%.This study provides new ideas for data security protection of remote disaster recovery systems.
