线上社交网络访问控制模型综述

Survey on Access Control Models for Online Social Networks

就线上社交网络访问控制模型的研究现状进行了分析、总结,指出当前研究中存在的关键问题和面临的挑战,并对此类模型的发展趋势和未来研究方向做出预测.线上社交网络方兴未艾,数据共享、隐私保护等问题日渐引起公众注意.作为信息安全手段,传统访问控制模型已不适应线上社交网络复杂环境下的安全需求.近年来针对线上社交网络访问控制模型的研究正成为热点问题,多个研究小组均从不同角度提出了新的访问控制模型.

The research status of access control models for online social networks was analyzed and summarized. The key problems and challenges were also pointed out, and some development trends and future research directions was proposed. Along with the explosive development of online social networks, problems such as data sharing and privacy preservation are gradually grabbing the attention of the public. As information security mechanism, traditional access control models are incompetent to meet the security requirements under the complex circumstances of online social networks. Recent years, research on access control models for online social networks is becoming a hot topic and many new access control models have been proposed based on different perspectives.
