Performance and security of AES, DES, and RSA in hybrid systems: An empirical analysis of triple encryption

Abstract

This study evaluates the performance and security of three cryptographic algorithms— AES, DES, and RSA—individually and in hybrid combinations. It aims to enhance information security through a novel three-step hybrid encryption method. Initially, each algorithm's execution time, memory usage, CPU usage, and data usage were analyzed separately. Subsequently, binary hybrid and triple hybrid techniques were assessed. The results indicate that AES is the fastest in terms of encryption speed, while RSA significantly increases memory usage in hybrid methods. DES exhibited the highest CPU usage. The triple hybrid method (AES + DES + RSA) demonstrated lower CPU and memory resource utilization, making it a viable option for applications requiring high security. This empirical analysis suggests that the triple hybrid method optimizes both performance and security, offering a balanced solution for secure data transmission. The findings contribute to the development of more effective data security methods and highlight the potential for further optimization and application in various contexts.
