摘要
随着海外产品在国内市场的推广,做好跨境电商的信任机制和防伪工作成为了新的技术难点。传统的集中式存储方式容易受到信息篡改的威胁,传统的第三方交易平台提供的信任机制无法满足物联网信息高度自动化趋势的需求。基于区块链技术记录交易信息,设计智能合约进行分级授权。利用基于身份的数字签名技术实现信息认证,提出一种授权与存证方案,并且做了相关的仿真实验,实现了一个去中心化、安全可靠的海外入境商品的授权与存证中心化系统。
With the promotion of overseas products in the domestic market,it has become a new technical difficulty to do a good job in the trust mechanism and anti-counterfeiting work of cross-border e-commerce.The traditional centralized storage method is vulnerable to the threat of information tampering,and the trust mechanism provided by the traditional third-party trading platform can not meet the needs of the trend of high automation of Internet of things information.Based on the block chain technology to record the transaction information,the smart contract was designed for hierarchical authorization,and the identity-based digital signature technology was used to realize the information authentication.An authorization and certificate storage scheme was proposed,and the related simulation experiments were done.A decentralized,safe and reliable authorization and certificate centralization system for overseas entry commodities is realized.
