Design and Optimization of Hybrid End-to-End Encryption Architecture for a Secure Web Application System

This project focuses on the design and optimization of a hybrid encryption architecture aimed at enhancing the security of web applications. Leveraging React JS for the frontend, Java with Spring Boot for the backend, and MySQL for the database, the system provides a robust solution for securing data transmissions and ensuring user privacy. The architecture integrates asymmetric elliptic curve encryption (ECC) with AES-GCM symmetric encryption in a hybrid protocol, employing a three-layer protection model. This model covers network-layer packet encryption, application-layer payload security, and session-level key management, providing an optimized key distribution mechanism based on ECDH key exchange. The hybrid encryption system demonstrates a marked improvement in performance over traditional methods, with a 12.3% increase in handshake speed and a 40% reduction in cryptographic latency. This architecture aims to balance computational efficiency with robust data confidentiality, making it suitable for large-scale web applications. Additionally, the system's use of forward confidentiality and real-time security measures positions it as a reliable tool for modern web security needs.
