域名解析是互联网信息服务的前提,但目前关于域名信誉评价的相关研究却尚不成熟。针对域名服务的复杂性、恶意攻击的普遍性以及用户需求的多样性等问题,提出了一种个性化域名信誉评价机制。主要贡献在于:(1)提出了基于多元指标的域名信誉评价框架;(2)设计了抵御恶意攻击的信誉计算模型,提高了计算精度和适应能力;(3)参考用户个人偏好区分域名类型,为用户选择偏好域名提供依据,优化用户体验。实验结果表明,该机制能准确反映域名的信誉状况,排除恶意评价的影响,并根据域名信誉值和用户个人偏好选择个性化域名服务,提升用户满意度。
Domain name resolution is the prerequisite of Internet information service, but at present the related research on reputation evaluation of domain name is not yet mature. In view of the complexity of domain name service, the universality of malicious attacks and the diversity of users’ needs, a personalized domain name reputation evaluation mechanism is proposed. The main contributions are as follows: (1) Put forward the domain reputation evaluation framework based on multivariate index; (2) Design a reputation computing model to resist malicious attacks and improve the computing precision and adaptability; (3) For users to choose the preferred domain name to provide a basis for optimizing the user experience. The experimental results show that this mechanism can accurately reflect the reputation status of domain name, exclude the influence of malicious evaluation, and choose personalized domain name service according to reputation value of domain name and personal preferences of users to improve user satisfaction.
