一种个性化域名信誉评价机制

A Customized Reputation Evaluation Mechanism for Domain Names

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 a foundation of the Internet, yet there is still no appropriate reputation evaluation mechanism for it. Considering the complexity of domain name service and the pervasiveness of malicious attacks, a customized reputation evaluation mechanism for domain names was presented. The main contributions are：（1） a domain reputation evaluation framework based on multi-index evaluation;（2） a variety of mechanisms that resist malicious attacks and improve the precision and adaptability of the reputation computation model;（3） theoretical support for users to choose their desired service with improved experience, taking into account the users＇ personal preferences. Results show that the proposed customized mechanism can accurately refl ect the reputation of domain names, fi ght against malicious evaluation attacks and improve user satisfaction.
