基于B+搜索树算法的区块链跨境电商溯源安全技术研究

Research on Cross-border E-commerce Traceability Security Technology of Blockchain Based on B+Search Tree Algorithm

针对区块链跨境电商在云存储中不可信、密文检索效率低、溯源准确率不足等问题,将B+搜索树与区块链跨境电商系统相结合,构建出基于B+搜索树的区块链跨境电商溯源系统,通过采用B+树索引结构提高了区块链跨境电商密文交易的加密和检索速度。实验证明,该方案在区块链跨境电商溯源中实现了高效交易密文检索,具有较高的溯源准确率和安全性。

In order to solve the problems of untrustworthy,low efficiency of ciphertext retrieval and insufficient traceability accuracy of blockchain cross-border e-commerce in cloud storage,a blockchain cross-border e-commerce traceability system based on B+search tree is constructed by combining B+search tree with blockchain cross-border e-commerce system.By using B+tree index structure,the encryption and retrieval speed of blockchain cross-border e-commerce ciphertext transaction is improved.Experimental results show that the scheme achieves efficient transaction ciphertext retrieval in cross-border e-commerce traceability of blockchain,and has high traceability accuracy and security.
