The security of archival privacy data in the cloud has become the main obstacle to the application of cloud computing in archives management. To this end, aiming at XML archives, this paper aims to present a privacy protection approach that can ensure the security of privacy data in the untrusted cloud, without compromising the system availability.,The basic idea of the approach is as follows. First, the privacy data before being submitted to the cloud should be strictly encrypted on a trusted client to ensure the security. Then, to query the encrypted data efficiently, the approach constructs some key feature data for the encrypted data, so that each XML query defined on the privacy data can be executed correctly in the cloud.,Finally, both theoretical analysis and experimental evaluation demonstrate the overall performance of the approach in terms of security, efficiency and accuracy.,This paper presents a valuable study attempting to protect privacy for the management of XML archives in a cloud environment, so it has a positive significance to promote the application of cloud computing in a digital archive system.

一种云环境中基于 XML 的档案管理的隐私保护方法

云端档案隐私数据的安全性已成为云计算在档案管理中应用的主要障碍。为此，本文针对XML档案，提出一种隐私保护方法，可以在不影响系统可用性的前提下，保证隐私数据在不可信云中的安全。该方法的基本思想如下。首先，隐私数据在提交到云端之前，应该在可信客户端上进行严格的加密，以确保安全。然后，为了高效查询加密数据，该方法为加密数据构造了一些关键特征数据，使得定义在隐私数据上的每个 XML 查询都可以在云端正确执行。，最后，
