+ 132% Sample Topics Here are some sample topics. There is no restriction in selecting the topic, you can either choose from one of these topics or select your own. The size of the project should reflect the size of the team. Basically, you must build a desktop/android application that utilizes cryptographic techniques/protocols to secure communication (or data at rest). Try to achieve confidentiality, integrity, availability, authentication, non-repudiation (preferably all of them, otherwise few of them based on the requirement). You must demonstrate the use of these cryptographic techniques by showing some outputs/visualization results or captured traffic such as through Wireshark. 1. Secure Chat Application • Description: Build an encrypted chat application for desktop or Android that ensures confidentiality, integrity, authentication, and non-repudiation. . Features: 0 End-to-end encryption using AES-256 or Signal Protocol. о Digital signatures for non-repudiation. о Message integrity verification using HMAC. O Secure login using two-factor authentication (2FA). O Server-side availability mechanisms (e.g., load balancing, backup storage). Technologies: Python (PyQt + PyCryptodome), Java (Android), Firebase for real-time messaging.
