Abstract

This research aims to improve security when every time a user logs in or makes a transaction, an OTP (One time pad) will be sent via email, the OTP code is generated randomly and can only be accessed by the account party that has a valid and valid OTP key at that time. certain. Using the one time pad algorithm provides a very high level of security, because the resulting OTP is unique for each transaction. However, its implementation requires strict discipline in key management and proper encryption or decryption processes so that it can function optimally. This system is designed for account user security to prevent data leaks, thereby minimizing the potential for crimes such as identity theft and fraud. The research results show that not a single OTP was repeated in the 10 transactions carried out. Each OTP code generated is unique and different from previous OTPs, both on successful and failed transactions, proving the effectiveness of the system. This website was created using Visual Studio Code to ensure a stable and efficient system implementation

Abstract

Currently, technological developments are increasingly advanced and developing, technological developments that are very rapid with the development of the times to meet human needs. One of them is the need for safe and comfortable home technology. The application of technology in the house is to use the concept of smart home by using firewall network security. Firewall on a smart home network is a concept where Internet of Things devices are safe from hacking by unknown people and cannot be controlled by other smartphone devices. Simulation is an important part of the application of the concept that will be carried out, especially to find out that research and studies are carried out using the simulation method as a way to solve problems. Cisco Packet Tracer 7.3 is an application that can help in terms of simulating Internet of Things devices. The results obtained from the firewall security concept simulation are that in the use of IoT devices such as house doors, windows, garages, lights, webcams and air conditioners are guaranteed to be secure because the devices that have permissions that can be connected.
