Secure communication and authentication using Raspberry Pi

Secure communication and authentication are two very important factors when it comes to applications such as payments. Since payments involve critical information such as user account number, pin, balance, etc., it becomes very vulnerable to fraudulent elements that want to gain access to this information illegally. Thus, this hardware and algorithm aims at creating a mobile payment terminal through which transactions can be carried out securely using the Transport Layer Security (TLS) protocol through a Raspberry Pi module.
