Generating 56-bit passwords using Markov Models (and Charles Dickens)

نویسنده

  • John Clements
چکیده

We describe a password generation scheme based on Markov models built from English text (specifically, Charles Dickens’ A Tale Of Two Cities). We show a (linear-running-time) bijection between random bitstrings of any desired length and generated text, ensuring that all passwords are generated with equal probability. We observe that the generated passwords appear to strike a reasonable balance between memorability and security. Using the system, we get 56bit passwords like The cusay is wither?" t, rather than passwords like tQ$%Xc4Ef.

Adaptive Password-Strength Meters from Markov Models

Measuring the strength of passwords is crucial to ensure the security of password-based authentication. However, current methods to measure password strength have limited accuracy, first, because they use rules that are too simple to capture the complexity of passwords, and second, because password frequencies widely differ from one application to another. In this paper, we present the concept ...
