TITLE	Design and Implementation of a Hybrid Database Encryption Model
ABSTRACT	The rapid expansion of digital databases has brought significant concerns regarding the security and confidentiality of stored data. Traditional encryption techniques such as symmetric or asymmetric cryptography provide strong protection, yet each approach has limitations in scalability, computational cost, and secure key distribution. This paper presents the design and implementation of a Hybrid Database Encryption Model (HDEM) combining symmetric Advanced Encryption Standard (AES-256) for data encryption and an asymmetric RSA-4096 mechanism for secure key exchange and management. The proposed hybrid approach enhances data confidentiality, minimizes performance overhead, and strengthens resilience against brute-force and insider attacks. Implementation and experimental validation were performed on a MySQL database using Python-based middleware. Results demonstrate that hybrid encryption improves security efficiency while maintaining acceptable system performance, making it suitable for healthcare, banking, and enterprise applications.
