A SYSTEMATIC REVIEW OF HYBRID CRYPTOGRAPHIC TECHNIQUES FOR ENHANCING SECURITY IN CLOUD DATA STORAGE
Keywords:
hybrid cryptography, cloud data security, performance metrics, multi-format encryption, data integrityAbstract
Cloud computing has revolutionised modern organisational operations by offering agility and cost-effectiveness. However, declining customer confidence due to frequent data breaches remains a significant barrier to adoption. Reports indicate that 99% of compromised data in recent years was unencrypted, underscoring the inadequacy of traditional security measures. This study explores the transition from single-method cryptographic approaches to hybrid models that combine symmetric and asymmetric algorithms. Through a systematic review of 51 contemporary studies, this paper identifies critical flaws in existing hybrid frameworks, including high computational complexity and limited support for diverse file formats like audio and video. The findings suggest that while hybrid models improve data confidentiality, significant gaps remain in multi-factor authentication and processing efficiency. This research provides a foundation for developing a high-performance hybrid cryptographic framework designed to restore executive and consumer trust in cloud storage environments.References
