Abstract

Cloud computing is a modern-day infrastructure for millions of applications on the Internet, and migrating to the cloud continues to pose a concern of exposing sensitive information's. Confidential information is susceptible to leak in the public domain if the storage service is misconfigured. So, the Cloud service provider (CSP) encourages organisations to enable encryption, relying primarily on the Advanced Encryption Standard (AES) to secure data. Consequently, the fundamental goal of this research is to undertake an alternative algorithm called XChaCha20 for file encryption in Cloud infrastructure and to evaluate XChaCha20 as compared to AES. The comprehensive experimental evaluation showed that XChaCha20 outperforms AES in terms of metrics such as execution time, keyspace analysis and overall throughput increased by thirty percentage while working with large files.
