密码猜测的多臂强盗方法

Multi-armed bandit approach to password guessing

Hazel Murray, David Malone

摘要:

多臂强盗是赌徒面对许多不同机器(强盗)时所面临问题的数学解释。赌徒想要探索不同的机器,以发现哪台机器提供最好的回报,但同时想要利用最有利可图的机器。密码猜测者也面临着类似的困境。他们有泄露的密码集列表,单词词典和用户的人口统计信息,但他们不知道哪本词典会获得最好的回报。在本文中,我们提供了一个框架,使用多臂强盗问题的背景下,密码猜测,并使用一些例子来表明,它可以是有效的。

英文摘要:

The multi-armed bandit is a mathematical interpretation of the problem a gambler faces when confronted with a number of different machines (bandits). The gambler wants to explore different machines to discover which machine offers the best rewards, but simultaneously wants to exploit the most profitable machine. A password guesser is faced with a similar dilemma. They have lists of leaked password sets, dictionaries of words, and demographic information about the users, but they don't know which dictionary will reap the best rewards. In this paper we provide a framework for using the multi-armed bandit problem in the context of the password guesser and use some examples to show that it can be effective.
