基于社会信任的恶意网页协防机制

Collaborative defending scheme against malicious Web pages based on social trust

针对恶意网页的威胁,提出了一种基于社会信任的分布式恶意网页协作防御机制:结合第三方专业服务机构提供的恶意网址列表,并利用社会网络中好友间的直接信任和间接信任获取好友对网页的评价信息,集成好友的安全浏览经验形成网页综合评价;每个用户都与其好友进行协作,形成一个网状的防御体系。实验结果表明,该机制能够有效减少恶意网页的访问量,提高社会网络防御恶意网页的能力。

To deal with the threat of malicious Web pages, a distributed defending scheme against malicious Web pages based on social trust was proposed. Besides the malicious URL list from third-party professional organizations, the direct and indirect trust relations between friends in social network were used to obtain evaluations of Web pages. The experiences about Web surfing from a user＇s friends were collected to result in synthetical evaluations on his computer. Each user cooperated with his friends, so that a defending system was formed on the overall perspective, which can improve the defending ability of the social network against malicious Web pages. The experiment results indicate that the visits of malicious Web pages under the scheme decrease obviously than the methods without social trust.
