摘要: 自“数据+业务”的双中台架构被提出以来, 中台间数据进行安全交互的效能显得尤为重要. 基于此, 本研究提出了一种高效的交互式协议, 在借助区块链双链结构保证数据安全可信的情况下, 改善了内生性 数据在中台间交互效率低的问题. 对新协议中核心的门限签名技术进行实验模拟的结果表明新协议在链 下签名、链上验签过程中比传统单一链上签名及验签的方法节省了 42.1% 的时间成本. 新协议对中台融合 区块链技术、加快中台与区块链的广泛实践均具有积极推动作用.

Abstract: Since dual-middle platform architecture of “data and business” was first proposed, the efficiency of secure data interaction between middle platforms has become particularly important. This paper proposes an efficient interaction protocol, while ensuring data security and credibility with the help of a blockchain dual-chain structure, to optimize the efficiency of endogenous data interaction between middle platforms. By extracting the core threshold signature technology in the new protocol, the simulation experiment showed that the protocol reduced 42.1% of the overhead time used in the off-chain signature and on-chain verification processes compared with the method for traditional single signature and on-chain verification. The new protocol will have a positive impact on the integration of blockchain technology in the middle platform and on accelerating the overall adoption of the middle platform and blockchain.
