Advanced Techniques in Dynamic Key Management and Multilayered Security for Securing Cloud Infrastructures Using Key-Aggregate Encryption Method

Effective security protocols and dynamic key management are crucial for robust cloud infrastructure protection. This study compares the Key-Aggregate Encryption Scheme (KAC) with traditional methods, highlighting KAC's streamlined approach to reducing complexity and enhancing performance. By analyzing delegation ratios across One-to-One, Tree-Based, and Proposed System methods, the research highlights the proposed system's ability to maintain a fixed number of aggregate keys, simplifying management and improving efficiency. Furthermore, it examines the relationship between file size and encryption duration, showing that larger files require more time, and investigates how content types, such as text and images, affect encryption processes. These findings underscore the importance of adaptive security protocols and efficient key management in optimizing cloud security, offering insights into advancing secure data handling and transmission in cloud environments.
