摘要
阐述了密钥集中管理的数据安全删除、密钥分散管理的数据安全删除和数据定时发布兼自毁等三方面的研究进展,围绕数据自毁、细粒度访问控制、抵抗攻击能力等因素,分析了相关的各种技术方法的优势和不足,并探讨未来的研究方向。
The paper overviewed the research progress in three aspects such as the data secure deletion of key centralized management, key dispersion management and timed-release with data self-destruction. Then it analyzed the advantages and disadvantages of various technical methods according to the factors of data self destruction, fine-grained access control, resistance to attack ability. At last, it also gave some direction for the future research.
