A Study on Markov Chain Password using Bayesian Inference

Passwords are the primary line of security against unlawful access to computer. Password security is fundamental to the protection of information systems. It is sound acknowledged truth that user chosen passwords are to some extent predictable. To make it unpredictable user can create Markov chain based passwords. This paper discusses about the analysis on passwords created using Markov Chain and Comparative analysis with common passwords. Bayesian Principle has been successfully used to analyze the strength and weakness of Markov chain passwords.
