基于纠错码的数据分片传输方案

DATA SEGMENTATION TRANSMISSION SCHEME BASED ON ERROR CORRECTION CODE

切片重组技术是将完整数据分成若干切片来保护其在传输和重组过程中隐私性的方法。为了进一步保证数据的安全,同时提高传输的鲁棒性,提出一种基于纠错码技术的数据分片传输方案。将完整数据切分后采用Reed-Solomon码进行编码,并利用可更新哈希链生成共享密钥对切片顺序进行置换,汇聚节点可利用满足限值的部分切片来恢复原始数据。分析和仿真证明了该方案中数据的隐私性和传输的鲁棒性,并减少了攻击或损坏对数据传输的影响。

Slice recombination technology is one of the main methods for data security transmission in wireless networks,which divides the complete data into several slices and then recombines them.In order to further ensure the security of data and improve the robustness of transmission,this paper proposes a data fragmentation transmission scheme based on error correction code.In this scheme,the complete data were segmented,and Reed-Solomon code was used to encode them.The shared key generated by the updatable hash chain was used to replace the slice order.The aggregation node could recover the original data by using partial slices satisfying the limit.The analysis and simulation show that this scheme not only guarantees the privacy in the process of data transmission,but also improves the robustness of data transmission and reduces the impact of attack or damage on data transmission.
