摘要
分析了数据起源需要满足的完整性要求和可能遭受到的完整性威胁,制定了通过电子签名和哈希图等技术手段来保证数据起源完整性的方案.阐述了该方案的安全性,并提出了安全起源的下一步研究内容.
Provenance can locate the mistakes in the process of data derived, it also can verify the credibility of the current data object. Both the needed integrity requirements and potential integri- ty threats of data provenance are analyzed. The integrity scheme is formulated mainly through the electronic signature and hash graph to ensure the integrity of provenance. Finally, we expound the safety of the scheme and put forward next study of securing provenance.
