摘要:

针对现有数据共享方案效率低及联盟链存储压力大的问题,文章提出一种基于联盟链和Asmuth-Bloom秘密共享算法的数据共享方案。该方案通过细粒度访问控制解决敏感数据泄露问题,并提高共享过程中的秘密重构效率;同时通过星际文件系统实现共享数据的安全存储,有效降低联盟链各节点的存储压力。安全性分析及实验结果表明,该方案具有正确性、安全性和高效性。

Abstract:

Aiming at the problems of low efficiency of data sharing scheme and high storage pressure on the consortium blockchain, an attribute-encrypted data-sharing scheme based on Asmuth-Bloom secret sharing algorithm is proposed. The scheme solves the leakage problem of sensitive data through fine-grained access control and improves the efficiency of secret reconstruction in the sharing process. At the same time, it realizes the secure storage of through interstellar file system and effectively reduces the storage pressure on the consortium blockchain network. Meanwhile, it realizes the secure storage of data through the inter planetary file system and effectively reduces the storage pressure of each node on the consortium blockchain network. The analysis and experimental results show that the scheme is correct, safe and efficient.

Key words: consortium blockchain, Asmuth-Bloom, attribute-based encryption, data sharing
