Anti-phishing technology has been a research hotspot in recent years. In this paper, the relationship of domain names, domain name system and phishing is discussed. A novel anti-phishing framework based on trustworthy domain names is put forward with methods to secure the trustworthy factors of domain name from three domains. Key technologies and subsystems are described subsequently, and a comparison is done with an email-based phishing webpage detection system. Analysis shows that address phishing issues from basic resources have the advantage of a wider range of information resources, a faster response time, a more convenient management system and an audit, which is also instructive for bad Internent governance.
