Non-linguistic systems as a way to make a password secure but memorable

Abstract:

This article is based on the study of ways to create a secure password by integrating symbols from non-linguistic sign systems, in order to combine cryptographic strength and ease of memorization. This is relevant, as the old ways of complicating the password become obsolete, in view of their triviality and, as a result, susceptibility to hacking. Our research is based on the use of a system of symbols from various fields of interest (chemistry, programming, music, etc.) in the password. We take into account the individual preferences of users, so that it would be easier for them to build an associative chain when remembering a password, and also considered the susceptibility of passwords obtained using the password techniques we proposed to the most common cyber-attacks. The respondents created one password on their own, and the second with the help of the proposed methods. The complexity and security of the password was estimated in terms of entropy, as well as using specialized programs. Using the proposed methods reduced the number of insecure keys.
