By introducing a number of computational statistical techniques and based on fourteen large-scale datasets, which consist of 127.7 million real- world passwords, we for the first time show that Zipf's law natively exists in the popular (and thus vulnerable) part of user- generated passwords. ...
1: Zipf’s Law in Passwords 基于密码的身份验证仍然是互联网上用户身份验证的主要机制。尽管它无处不在,但这种身份验证伴随着生成密码的困境,这对于强大的攻击者来说很难破解,但普通用户很容易记住。 The diversity of password strength meters and rules brings about an enormous variety of requirements between...

Zipf's Law in Passwords 来自 IEEEXplore 喜欢 0 阅读量: 345 作者:W Ding,H Cheng,W Ping,X Huang,G Jian 摘要: Despite three decades of intensive research, it remains an open question as to what is the underlying distribution of user-generated passwords. In this work, we make a ...
Fortunately, researchers recently reveal that user-chosen passwords generally follow the Zipf’s law, a distribution which is vastly different from the uniform one. In this work, we explore a number of foundational security implications of the Zipf-distribution assumption about passwords. Firstly, we...
The paper also examines the existence of Zipf's law on Iranian passwords as the most well-known distribution for passwords. Password analysis of Iranian users shows that the popular password length between Iranian users and users of other countries is not much different, but in terms of the ...
Zipf's Law is commonly observed in lists of chosen words. Using password lists from four different on-line sources, we will investigate if Zipf's law is a good candidate for describing the frequency with which passwords are chosen. We look at a number of standard statistics, used to mea-...
