摘要
在数字化教育快速发展的背景下,教学平台数据的安全性和共享效率面临挑战。中心化数据管理系统存在数据泄露风险、单点故障等问题。因此,研究提出了一种基于区块链技术的分布式秘密共享区块链安全模型,通过秘密分割技术和分布式存储提升教学平台数据共享的安全性与效率。实验结果显示,模型数据泄露率仅为0.02%,远低于传统区块链系统的0.15%和Shamir秘密分享方案的0.05%。数据恢复准确率高达98.75%,优于其他方法。此外,数据访问延迟为35 ms,系统扩展性下降率仅为3.5%。在数据传输速度与效率方面,模型在10 GB至100 GB的数据量下,传输速度从25.65 MB/s下降至12.83 MB/s,下降幅度较小。研究为教学平台的数据安全共享提供了一种新型解决方案,具有重要的实践意义和应用价值。
Against the backdrop of the rapid development of digital education,the security and sharing efficiency of data on educational platforms are facing challenges.Centralized data management systems are prone to data leakage risks and single-point failures.Therefore,this study proposes a distributed secret sharing blockchain security model based on blockchain technology,which enhances the security and efficiency of data sharing on educational platforms through secret sharing technology and distributed storage.Experimental results show that the model’s data leakage rate is only 0.02%,significantly lower than the 0.15% of traditional blockchain systems and the 0.05% of Shamir's Secret Sharing scheme.The data recovery accuracy rate is as high as 98.75%,superior to other methods.In addition,the data access latency is 35 ms,and the system scalability decrease rate is only 3.5%.In terms of data transmission speed and efficiency,the model’s transmission speed decreases from 25.65 MB/s to 12.83 MB/s for data volumes from 10 GB to 100 GB,with a relatively small decrease.The study provides a new solution for secure data sharing on educational platforms,which has important practical significance and application value.
