A scheme to create secured random password using Markov chain

Abstract

Habitually, access to computer systems is based on the use of alphanumeric passwords. Password affords the foremost line of protection against illicit access to computer. Password security is of course only one factor of overall system security. Even though it is an essential component, passwords are measured as the fragile link in computer security. Most users will make use of simple passwords. Simple passwords are easy to memorize, but in the same sense easy to crack!! However, the common user is likely to use simple password and more often the same password for different login. This makes them vulnerable to various types of cyber attacks. To create/generate secured random passwords, in this paper, we describe a new scheme of creation/generation of passwords using Markov chain technique. The tree structure of creation/generation of passwords using Markov chain technique is also specified.
