一种改进的云存储平台权限管理机制设计
Improved design of cloud-storage privilege revoking management mechanism
摘要
Abstract
In order to effectively solve overhead computing and bandwidth, high complexity problems about user access privileges revoking of cloud-storage service, this paper designs a cloud-storage Privilege Revoking Optimizing mechanism based on Dynamic Re-encryption(DR-PRO). Firstly, DR-PRO uses (k'n) threshold algorithm of secret sharing scheme, the data information is divided into a number of blocks, and it achieves re-encryption to a data block. Secondly, it succes-sively achieves user access privilege revoking by data cutting, data reconstructing, data publishing, data extracting and data revoking sub-algorithms. Theoretical analysis and experimental evaluation show that, DR-PRO ensures high data security, effectively reduces the computing and bandwidth overhead, further optimizes and improves the performance.关键词
