基于精确再生码的秘密共享方案OA北大核心CSCDCSTPCD
Secret sharing scheme based on exact regenerating codes
为解决云存储系统中数据安全性问题,利用精确再生码构造一种新的(t,n)门限秘密共享方案.方案由子秘密的分发、原始秘密的恢复和子秘密丢失者的数据重建共3种算法组成.子秘密的分发就是将原始秘密先进行分块,再进行纠删编码,最后按一定的规则将编码后的数据块分发给n个分享者.选取t个分享者提供的数据块,按纠删码的译码算法恢复原始秘密.选取t个以上分享者的数据块,按精确再生码的译码算法重建出子秘密丢失者的数据.研究结果表明:访方案是一种信息论安全的门限体制,…查看全部>>
In order to solve data security issues in cloud storage system, a new (t, n) threshold secret sharing scheme was constructed based on exact regenerating codes. The scheme was composed of three algorithms which were distribution of share secret, recovery of the original secret and data reconstruction of lost share secrets. Distribution of share secret means that original secret is firstly split into some pieces, then is erasured codes, and finally is distribu…查看全部>>
