Research on Password Reuse Behavior and Multidimensional Password System
摘要
Abstract
The rapid development of the Internet and highly decentralized network services prompts the majority of Internet users to register more accounts,and causes a high incidence of password reuse,which makes the user information leakage risks facing the domino-style. Based on the data of Internet password leak door at the end of 2011 as well as the college students online survey,this paper analyzes the structural characteristics and reuse behavior of netizen passwords in detail,and thus designs a multidimensional password system which infuses into the information dimensions and classified management. This system,based on the structure of"seed-reuse code",includes three dimensions:the content dimension contains multi-independent"information factor",which constitutes the main part of the password,the formal dimension is responsible for conversion formatting,in order to enhance the complexity and security of the password,and space-time dimension is targeted designed to protect the password timeliness and reusability. Through comparative analysis and quantitative analysis,the password system not only has good memorability and convenience,but also can effectively resist the violent attacks and acquaintances attacks.关键词
