Abstract

The rapid advancement of information and communication technology has led to an increased use of web applications, but also brought challenges in data security. The widely used HTTP protocol remains vulnerable to threats such as data theft and cyber-attacks. One solution to mitigate these issues is the use of client-side encryption methods, such as the RC5 algorithm, which provides high flexibility in encryption parameter configurations. This research analyzes the implementation of the RC5 algorithm in enhancing web application data security. A web application prototype utilizing RC5 encryption was developed and tested for encryption time, decryption time, and memory consumption. Test results indicate that the RC5 algorithm enhances data security without significantly compromising application performance. However, an increase in processing load was observed on low-specification devices. This study also highlights the importance of adjusting RC5 parameters to balance security and performance
