Improving Authentication System Using Dual-Simplex Communication
As the world is becoming more and more connected due to humongous growth of the Internet, the task to secure a communication network is becoming more challenging. The communication system has evolved a lot since its inception to tackle the overgrowing traffic as well as the security challenges that come along with the increased traffic. The one thing that has remained common in all the communication or authentication systems is the use of a two-way communication channel (a channel which can transmit data in both the directions). A two-way communication channel can be a goldmine for an attacker, as it is a single point from where an attacker can grab all the data containing all the challenges and responses and therefore the attacker becomes capable of analyzing the data and plan network attacks. This project tries to design a one-way authentication system to prove this idea as a proof of concept. With protocol design being the major part, the other part of the project is to discuss on the changes required and how can they be achieved in the current infrastructure to make the design backward compatible with the existing communication system. The project analyses the designed protocol against Man-In-The-Middle, spoofing and sniffing attacks using Kali tools. The project is able to successfully conclude that this idea deserves the time and attention of the research community as it shows positive results in defending a network.
