Authentication Mechanisms in the Cyber Security Domain: Hash Code, OTP, and CAPTCHA

Abstract

Abstract: It is important to integrate security as part of system and software development. A computer can be accessed by anyone. Cyber security acts against hackers. Security begins with authentication. Access to systems, networks, databases, websites, and services are regulated using authentication. The most fundamental category of verification is done with usernames and passwords. In our paper, we propose new approaches to each of these authentication mechanisms, which include hash code message authentication, the Entirely Automated Public Turing Test to Notify Computer systems and Human beings Apart (CAPTCHA), and one-time passwords
