11月11日上午10:00-11:00,西安电子科技大学闫峥教授应邀在广州大学行政西前座428会议室给计算机科学网络与工程学院师生们做了一场题为“Digitalizing Trust for Securing Pervasive Social Networking with Privacy Preservation”的学术报告。会议由我院副院长王国军教授主持。 报告中,闫峥教授首先介绍了社交网络(Social Networking)的发展历史,从最初仅具备简单聊天功能的基于web端的社交网络,到今天集各种功能于一身的普适社交网络(Pervasive Social Networking, PSN)。而发展至今,人们越发关注它存在的安全威胁,以及带来的一系列隐私泄露的风险,并且突出信任(Trust)在PSN中起着决定性作用。闫峥教授着重介绍了其在Trust Social Networking项目的一些研究成果,尤其是在社交网络数据访问控制的适应性和匿名认证两个方面。闫峥教授介绍了基于多维信任级别的数据保护和数据访问控制方案设计及实现,以及通过对任意数量的授权信息颁发方进行无证书认证和聚合签名验证,以此来保证PSN节点的可信。最后,就社交网络与区块链,机器学习等技术结合简单阐述了对未来工作的展望。报告开展的过程中,全体师生都非常积极地参与讨论,对报告中涉及到的信任等级(Trust Level)如何评定,各个节点的信任值(Trust Value)怎么计算,以及区块链技术如何应用到PSN等问题进行热烈的讨论。此次报告让在场的师生获益良多。
