The advances of Internet technology has resulted in the rapid and pervasive development of e-commerce, which has not only changed the production and operation mode of many enterprises, but also affected the economic development mode of the whole society. This trend has incurred a strong need to store and process large amounts of sensitive data. The traditional data storage and search solutions cannot meet such requirements. To tackle this problem, in this article, we proposed Consortium Blockchain-based Distributed Secure Search (CBDSS) Scheme over encrypted data in e-Commerce environment. By integrating the blockchain and searchable encryption model, sensitive data can be effectively protected. The consortium blockchain can ensure that only authorized nodes can join the system. To fairly assign nodes for the search tasks, we developed an endorsement strategy in which two agent roles are set up to divide and match the search tasks with the virtual resources according to the load capacity of each node. The security analysis and experiments are conducted to evaluate the performance of our proposed scheme. The evaluation results have proved the reliability and security of our scheme over existing methods.

实现对电子商务加密数据的安全搜索

互联网技术的进步带来了电子商务的迅猛发展，不仅改变了许多企业的生产经营方式，也影响了整个社会的经济发展方式。这一趋势引发了存储和处理大量敏感数据的强烈需求。传统的数据存储和搜索解决方案无法满足这样的需求。为了解决这个问题，在本文中，我们提出了基于联盟区块链的分布式安全搜索（CBDSS）方案，用于电子商务环境中的加密数据。通过整合区块链和可搜索的加密模型，可以有效保护敏感数据。联盟区块链可以确保只有授权的节点才能加入系统。为了公平地为搜索任务分配节点，我们开发了一种背书策略，其中设置了两个代理角色，根据每个节点的负载能力将搜索任务与虚拟资源进行划分和匹配。进行安全分析和实验以评估我们提出的方案的性能。评估结果证明了我们的方案相对于现有方法的可靠性和安全性。
