Generally speaking, this dissertation details the creation of an enhanced hybrid encryption setup. It brings together RSA and ElGamal alongside clustering and lattice-based crypto, aiming to beef up cloud environment security in real-time. The research tackles a serious issue: cloud datas vulnerability to unauthorized peeps and security risks, often due to what traditional encryption can't handle. Data was systematically gathered and looked atthink current encryption performance, user access, and how well hybrid methods do. The study shows a clear boost in data protection, cutting down computational load and boosting resistance to common attacks. Turns out, this framework doesnt just up the security for private healthcare info, keeping it safe during transfer and storage, but it also helps meet regulatory rules. Looking beyond healthcare, this research sets a strong encryption plan, which could help secure cloud systems across different areas, maybe building more trust in our digital setups. Therefore, this beefed-up hybrid encryption thing is pretty important for protecting key data in an increasingly linked-up world, underlining how crucial top-notch security is for keeping privacy alive and sensitive info under wraps.
