Title

Secure file storage for shared hosting using multi-layered cryptography algorithm

Abstract

This study focuses on the implementation and evaluation of a secure file storage system for shared hosting services using a multi-layered cryptography algorithm. The primary objectives were to assess the efficacy of hybrid/multi-layered cryptography in protecting cloud-based data, develop a cloud-based file system with AES, DES, and blowfish encryption algorithms, and evaluate the algorithm's performance in terms of speed, efficiency, and key distribution. The prototyping software development model was employed to create a functional system that utilizes multiple encryption algorithms. Functional requirements included robust security during file transfer, resistance against attacks, and consideration of speed and efficiency. The evaluation revealed that the system successfully provided robust security for file-sharing, with longer key lengths enhancing resistance to attacks. However, file size affected encryption and decryption speed. The study's findings align with previous research, emphasizing the importance of strong encryption algorithms, long key lengths, and the trade-off between security and speed. The results affirm the effectiveness of the multi-layered cryptography algorithm in file encryption for shared hosting services. Future work should explore integrating advanced cryptographic techniques, optimizing performance, conducting real-world testing, and implementing continuous monitoring for enhanced security.
