Quantum-Resistant Cryptography with Malware Resilience for Secure Communication
S Athithian, S Raghavi, Anita Rose J T · 2025
The forthcoming emergence of quantum computing presents significant risks to conventional cryptographic frameworks, including RSA and ECC, which underpin secure communication infrastructures. In response to this challenge, the present study introduces an extensive framework that amalgamates quantum-resistant cryptographic methodologies with improved malware resilience strategies. By utilizing the lattice-based CRYSTALS-Kyber algorithm, this system guarantees strong post-quantum security while preserving computational efficiency. The framework facilitates a secure key exchange protocol that generates AES-256 keys for symmetric encryption and guarantees secured high-speed communications. Apart from that, malware resiliency features such as sandboxed environments and integrity verification strengthen the system against ever-evolving cyber threats. A proof-of-concept chat application demonstrates the effectiveness of the proposed system in terms of depicting real-time secure communication under quantum-resistant encryption. This is an approach towards a scalable and future-proof solution to secure communication in a post-quantum era with both academic research implications and real-world applications. Further enhancements include sophisticated malware detection techniques and broader system optimization.
