在本文中,我们展示了如何划分数据块,这样可以很容易地从任何块中重建,但是即使完全了解k- 1块,也绝对没有揭示关于d的信息。该技术支持为加密系统构建健壮的密钥管理方案,即使不幸破坏了一半的部分,并且安全漏洞暴露了剩下的部分,也可以安全可靠地运行。
In this paper we show how to divide dataDintonpieces in such a way thatDis easily reconstructable from anykpieces, but even complete knowledge ofk- 1 pieces reveals absolutely no information aboutD. This technique enables the construction of robust key management schemes for cryptographic systems that can function securely and reliably even when misfortunes destroy half the pieces and security breaches expose all but one of the remaining pieces.
