201849日,英国萨里大学梁开泰副教授访问网络安全与密码技术重点实验室,并于当日下午在成功楼603作了题为可保护隐私的外包数据分享和搜索”的学术报告。

在报告中,梁开泰副教授先介绍了报告背景,并指出在云/大数据时代,个人和行业可以将他们的数据外包到“未知”云,以消除本地数据存储和管理的成本。云支持的远程数据存储和检索服务允许用户随时随地访问数据。然而,由于数据超出了“物理控制”,它们会为用户带来安全和隐私问题。进而引出解决问题的办法,因此他详细介绍了基于云的数据搜索与共享。在讲述加密过的外包数据分享之后,他着重介绍了代理重加密技术和可搜索加密技术的研究发展历史和相关应用。最后,他对可保护隐私的外包数据分享和搜索作出简单的总结与工作展望。

报告之后,梁开泰副教授耐心解答了老师和同学们所提出的许多有趣的问题,大家对此次报告好评如潮,收获颇丰。
