Secure Chat Room Application Using AES-GCM Encryption and SHA-256

This research paper investigates the security principles of a chatroom application. The study aims to ensure the security and privacy of user information while maintaining user convenience and ease of use. A literature review and analysis identified potential security vulnerabilities, including unauthorized access to user accounts, insecure transmission and storage of messages, and possible man-in-the-middle attacks or data breaches. To address these challenges, a new secure chatroom application is proposed. It integrates an in-depth security strategy to ensure high communication protection. It includes a) Deployment of user authentication and password security level verification, b) Integration of encryption to ensure secure messaging and user data storage using Advanced Encryption Standard and SHA-256 hashing, respectively, c) Adoption of no message history features to ensure the availability of only current conversation and no older message are retrieved, d) Integration of client handler to manage the interaction between client and server and ensure efficient and smooth chatroom operations, and d) a user-friendly GUI that serve the basic of communication with high-security level and low resource consumption. The research findings suggest that a balance can be achieved between security and user convenience, resulting in a chatroom application that is both secure and easy to use.
