Java-Based Hardware-Oriented Secure Messaging System Using Symmetric Encryption Techniques

Abstract

This paper presents a hardware-oriented implementation of a secure message service leveraging symmetric cryptographic techniques, with development and simulation performed using Java. Symmetric encryption algorithms, particularly the Advanced Encryption Standard (AES), were employed for securing message transmission, optimizing both performance and resource usage. The primary goal is to enhance the energy efficiency of secure data transmission by selecting optimal cryptographic and compression algorithm pairs suitable for hardware implementation. Experimental results reveal that combining AES encryption with lightweight compression algorithms significantly reduces computational overhead and improves transmission efficiency.
