基于秘密分割的区块链安全数据共享模型
Blockchain secure data sharing model based on secret sharing
摘要
Abstract
Under the data sharing application,in view of the problem of data storage security and data overload caused by the distributed sharing and network-wide data synchronization characteristics of the blockchain,secret sharing data sharing model(SSDSM)based on the blockchain security data sharing model based on secret segmentation is proposed.The model randomly groups nodes in the whole network,and the shared data is chunked and saved in different node groups by the se-cret sharing algorithm,reducing data redundancy of a single node under the premise of ensuring that any single node cannot obtain the shared data.Experiments show that with the increase of the threshold,the partition time cost of SSDSM and data redundancy of a single node are significantly reduced,and the time cost of data recovery is maintained at a low level.SS-DSM,which combines security and low data load,is more suitable for a data sharing environment than other data sharing scenarios.关键词
