基于区块链的供应链可信数据管理
|
摘要
为解决传统供应链中贸易数据潜在伪造、篡改等安全问题,提出了一种基于区块链技术的供应链可信数据管理方案.首先,以智能合约将贸易规则代码化,防范履约风险和提高贸易数据处理可信性;其次,采用ZSS04方案和抽样技术交互完成贸易数据完整性检验;再次,设计了适用于供应链的分布式共识机制,以提高贸易数据存储可信性;最后,利用区块链技术所具有的原生特性实现非可信环境下的可信数据管理.分析以及实验结果表明,该方案能够为供应链中贸易数据管理提供新的思路和技术支持.
In order to solve the security problems such as potential tampering and forgery in the traditional supply chain of transaction data, this study proposes a new trusted data management scheme based on blockchain technology. First, an intelligent contract suitable for supply chain is designed to code trade rules in order to prevent performance risks and improve the credibility of trade data processing. Then, ZSS04 scheme and sampling techniques are used to complete transaction data integrity check. Furthermore, a distributed consensus mechanism for supply chain is designed to improve the reliability of trade data storage. Finally, the trusted data management in untrusted environment is realized by using the native characteristics of blockchain. Results show that the scheme can provide new ideas and technical support for transaction data management in supply chain.
