Hybrid Techniques for Shared File Security in Cloud Environment Using SHA-256

This research examines file protection in cloud environments using the SHA-256 algorithm. It evaluates secure hash variants in file transfer systems, aiming to improve throughput while meeting security requirements. Data analysis involved gathering and cleaning datasets, measuring encryption times, and applying statistical and graphical methods. Results show SHA-256 as an effective base for encryption, with parallel processing increasing efficiency when real-time speed is essential. The study highlights the value of transformational techniques to boost performance and recommends hybrid systems that combine SHA-256 with other algorithms for stronger security. These outcomes support further work on cryptographic methods to strengthen the safety and reliability of cloud infrastructures.
