基于适配器签名和盲混技术的电子资源交易方案设计与实现

Design and Implementation of An Electronic Resource Transation Scheme Using Adaptor Signature and Blind-Mixing

为解决第三方电子商务平台存在信用风险、交易不确定以及监管体系不完善的问题,出现许多利用区块链技术实现去中心化的方案,然而区块链交易透明且可追踪导致出现隐私泄露的新问题。针对该问题,采用适配器签名技术与盲混合技术,提出一种新颖的电子资源交易方案,解决了无可信第三方公平交易问题,保护了交易双方的隐私安全。经过安全性论证,该方案具有公平性、原子性和不可链接性。仿真实现表明,该方案具有良好的执行效率。

To solve the problems of credit risk,transaction uncertainty and imperfect regulatory system in third-party e-commerce platforms,many schemes using blockchain technology to achieve decentralization have emerged.However,blockchain transactions are transparent and traceable leading to the new problem of privacy leakage.To address the problem,a novel electronic resource transaction scheme is proposed using adaptor signature technology and blind-mixing technology,which solves the problem of fair transaction without a trusted third party and protects the privacy and security of both sides of the transaction.After the security demonstration,the scheme is fair,atomic and unlinkability.The simulation implementation shows that the solution has good execution efficiency.
