Abstract

One of the factors that affect the security of a network or system is user authentication, so that at times it can be said to be no longer safe. Brute force attacks on password systems are a dominant (static) potential way to penetrate network security or user authentication systems. One way to overcome these drawbacks is to use the One Time Password (OTP) algorithm. OTP is a password security system using dynamic passwords. The password will be valid for one session only. In this research, the author will analyse the reliability of the OTP algorithm by applying it to a LEGO Mindstorms robot. The robot will be designed as part of a system where the user will be safe to enter the default password, and then the system will change the password every session. The results of the questionnaire showed that 79% of users felt more secure, but more than 60% said it was difficult to do.
