I. Introduction
In an era of escalating cyber threats, establishing secure communication channels is imperative. The need for private and secure communication channels between devices is more important than ever in a time of fast technological advancement. Sensitive data must be protected against illegal access and interception as applications continue to infiltrate every aspect of our life [1]. In order to meet this urgent requirement, this research suggests a client-to-client communication system that is strengthened using strong encryption methods, one-time passwords (OTPs), and QR code encryption.
