摘要
社交网络(social network,SN)具有用户数目多、数据量大、信息开放、用户关系难以管理等特点.如何实现用户隐私保护、身份认证和数据访问控制,已成为社交网络中备受关注的安全问题.本文首先介绍了社交网络的基本概念、发展现状和主要技术,并结合社交网络的特点,从社交网络数据挖掘、传统威胁、身份窃取等方面分析其存在的主要安全威胁,总结其存在的安全风险.然后,阐述了几种较为完善的社交网络安全解决方案,并对其工作原理进行了分析和比较.最后,给出了社交网络安全研究的几个热点研究课题,并讨论了社交网络安全性研究的发展方向.
Social networks（SN） have the characteristics of immensity of data,huge clientele,openness in information sharing,difficult customer relationship management,etc.Security issues,such as privacy protection,identity authentication and data access control have increased enormously on such networks.The basic concept,present development and main technology of SN were introduced.And specific security risks according to its characteristics were also summarized from the aspects of data mining,traditional threats and identity theft on SN.Furthermore,several existing security solutions of SN were described,and their working principles were analyzed and compared.Finally,some hot security research topics were given and the future research directions were discussed.
